+* APM X-Gene 15Gbps Multi-purpose PHY nodes
+
+PHY nodes are defined to describe on-chip 15Gbps Multi-purpose PHY. Each
+PHY (pair of lanes) has its own node.
+
+Required properties:
+- compatible : Shall be "apm,xgene-phy".
+- reg : PHY memory resource is the SDS PHY access resource.
+- #phy-cells : Shall be 1 as it expects one argument for setting
+ the mode of the PHY. Possible values are 0 (SATA),
+ 1 (SGMII), 2 (PCIe), 3 (USB), and 4 (XFI).
+
+Optional properties:
+- status : Shall be "ok" if enabled or "disabled" if disabled.
+ Default is "ok".
+- clocks : Reference to the clock entry.
+- apm,tx-eye-tuning : Manual control to fine tune the capture of the serial
+ bit lines from the automatic calibrated position.
+ Two set of 3-tuple setting for each (up to 3)
+ supported link speed on the host. Range from 0 to
+ 127 in unit of one bit period. Default is 10.
+- apm,tx-eye-direction : Eye tuning manual control direction. 0 means sample
+ data earlier than the nominal sampling point. 1 means
+ sample data later than the nominal sampling point.
+ Two set of 3-tuple setting for each (up to 3)
+ supported link speed on the host. Default is 0.
+- apm,tx-boost-gain : Frequency boost AC (LSB 3-bit) and DC (2-bit)
+ gain control. Two set of 3-tuple setting for each
+ (up to 3) supported link speed on the host. Range is
+ between 0 to 31 in unit of dB. Default is 3.
+- apm,tx-amplitude : Amplitude control. Two set of 3-tuple setting for
+ each (up to 3) supported link speed on the host.
+ Range is between 0 to 199500 in unit of uV.
+ Default is 199500 uV.
+- apm,tx-pre-cursor1 : 1st pre-cursor emphasis taps control. Two set of
+ 3-tuple setting for each (up to 3) supported link
+ speed on the host. Range is 0 to 273000 in unit of
+ uV. Default is 0.
+- apm,tx-pre-cursor2 : 2st pre-cursor emphasis taps control. Two set of
+ 3-tuple setting for each (up to 3) supported link
+ speed on the host. Range is 0 to 127400 in unit uV.
+ Default is 0x0.
+- apm,tx-post-cursor : Post-cursor emphasis taps control. Two set of
+ 3-tuple setting for Gen1, Gen2, and Gen3. Range is
+ between 0 to 0x1f in unit of 18.2mV. Default is 0xf.
+- apm,tx-speed : Tx operating speed. One set of 3-tuple for each
+ supported link speed on the host.
+ 0 = 1-2Gbps
+ 1 = 2-4Gbps (1st tuple default)
+ 2 = 4-8Gbps
+ 3 = 8-15Gbps (2nd tuple default)
+ 4 = 2.5-4Gbps
+ 5 = 4-5Gbps
+ 6 = 5-6Gbps
+ 7 = 6-16Gbps (3rd tuple default)
+
+NOTE: PHY override parameters are board specific setting.
+
+Example:
+ phy1: phy@1f21a000 {
+ compatible = "apm,xgene-phy";
+ reg = <0x0 0x1f21a000 0x0 0x100>;
+ #phy-cells = <1>;
+ };

+ phy2: phy@1f22a000 {
+ compatible = "apm,xgene-phy";
+ reg = <0x0 0x1f22a000 0x0 0x100>;
+ #phy-cells = <1>;
+ };
+
+ phy3: phy@1f23a000 {

+Device tree binding for NVIDIA Tegra XUSB pad controller
+========================================================
+
+The Tegra XUSB pad controller manages a set of I/O lanes (with differential
+signals) which connect directly to pins/pads on the SoC package. Each lane
+is controlled by a HW block referred to as a "pad" in the Tegra hardware
+documentation. Each such "pad" may control either one or multiple lanes,
+and thus contains any logic common to all its lanes. Each lane can be
+separately configured and powered up.
+
+Some of the lanes are high-speed lanes, which can be used for PCIe, SATA or
+super-speed USB. Other lanes are for various types of low-speed, full-speed
+or high-speed USB (such as UTMI, ULPI and HSIC). The XUSB pad controller
+contains a software-configurable mux that sits between the I/O controller
+ports (e.g. PCIe) and the lanes.
+
+In addition to per-lane configuration, USB 3.0 ports may require additional
+settings on a per-board basis.
+
+Pads will be represented as children of the top-level XUSB pad controller
+device tree node. Each lane exposed by the pad will be represented by its
+own subnode and can be referenced by users of the lane using the standard
+PHY bindings, as described by the phy-bindings.txt file in this directory.
+
+The Tegra hardware documentation refers to the connection between the XUSB
+pad controller and the XUSB controller as "ports". This is confusing since
+"port" is typically used to denote the physical USB receptacle. The device
+tree binding in this document uses the term "port" to refer to the logical
+abstraction of the signals that are routed to a USB receptacle (i.e. a PHY
+for the USB signal, the VBUS power supply, the USB 2.0 companion port for
+USB 3.0 receptacles, ...).
+
+Required properties:
+--------------------
+- compatible: Must be:

+Pad nodes:
+==========
+
+A required child node named "pads" contains a list of subnodes, one for each
+of the pads exposed by the XUSB pad controller. Each pad may need additional
+resources that can be referenced in its pad node.
+
+The "status" property is used to enable or disable the use of a pad. If set
+to "disabled", the pad will not be used on the given board. In order to use
+the pad and any of its lanes, this property must be set to "okay".
+
+For Tegra124 and Tegra132, the following pads exist: usb2, ulpi, hsic, pcie
+and sata. No extra resources are required for operation of these pads.
+
+For Tegra210, the following pads exist: usb2, hsic, pcie and sata. Below is

+This document explains only the device tree data binding. For general
+information about PHY subsystem refer to Documentation/driver-api/phy/phy.rst
+
+PHY device node
+===============
+
+Required Properties:
+#phy-cells: Number of cells in a PHY specifier; The meaning of all those
+ cells is defined by the binding for the phy node. The PHY
+ provider can use the values in cells to find the appropriate
+ PHY.
+
+Optional Properties:
+phy-supply: Phandle to a regulator that provides power to the PHY. This
+ regulator will be managed during the PHY power on/off sequence.
+
+For example:
+
+phys: phy {
+ compatible = "xxx";
+ reg = <...>;
+ .
+ .
+ #phy-cells = <1>;
+ .
+ .
+};
+
+That node describes an IP block (PHY provider) that implements 2 different PHYs.
+In order to differentiate between these 2 PHYs, an additional specifier should be
+given while trying to get a reference to it.
+
+PHY user node
+=============
+
+Required Properties:
+phys : the phandle for the PHY device (used by the PHY subsystem; not to be
+ confused with the Ethernet specific 'phy' and 'phy-handle' properties,
+ see Documentation/devicetree/bindings/net/ethernet.txt for these)
+phy-names : the names of the PHY corresponding to the PHYs present in the
+ *phys* phandle
+
+Example 1:
+usb1: usb_otg_ss@xxx {
+ compatible = "xxx";
+ reg = <xxx>;
+ .
+ .
+ phys = <&usb2_phy>, <&usb3_phy>;
+ phy-names = "usb2phy", "usb3phy";
+ .
+ .
+};
+
+This node represents a controller that uses two PHYs, one for usb2 and one for
+usb3.
+
+Example 2:
+usb2: usb_otg_ss@xxx {
+ compatible = "xxx";
+ reg = <xxx>;
+ .
+ .
+ phys = <&phys 1>;
+ phy-names = "usbphy";
+ .
+ .
+};
+
+This node represents a controller that uses one of the PHYs of the PHY provider
+device defined previously. Note that the phy handle has an additional specifier
+"1" to differentiate between the two PHYs.

+STMicroelectronics STi MIPHY28LP PHY binding
+============================================
+
+This binding describes a miphy device that is used to control PHY hardware
+for SATA, PCIe or USB3.
+
+Required properties (controller (parent) node):
+- compatible : Should be "st,miphy28lp-phy".
+- st,syscfg : Should be a phandle of the system configuration register group
+ which contain the SATA, PCIe or USB3 mode setting bits.
+
+Required nodes : A sub-node is required for each channel the controller
+ provides. Address range information including the usual
+ 'reg' and 'reg-names' properties are used inside these
+ nodes to describe the controller's topology. These nodes
+ are translated by the driver's .xlate() function.
+
+Required properties (port (child) node):
+- #phy-cells : Should be 1 (See second example)
+ Cell after port phandle is device type from:
+ - PHY_TYPE_SATA
+ - PHY_TYPE_PCI
+ - PHY_TYPE_USB3
+- reg : Address and length of the register set for the device.
+- reg-names : The names of the register addresses corresponding to the registers
+ filled in "reg". It can also contain the offset of the system configuration
+ registers used as glue-logic to setup the device for SATA/PCIe or USB3
+ devices.
+- st,syscfg : Offset of the parent configuration register.
+- resets : phandle to the parent reset controller.
+- reset-names : Associated name must be "miphy-sw-rst".
+
+Optional properties (port (child) node):
+- st,osc-rdy : to check the MIPHY0_OSC_RDY status in the glue-logic. This
+ is not available in all the MiPHY. For example, for STiH407, only the
+ MiPHY0 has this bit.
+- st,osc-force-ext : to select the external oscillator. This can change from
+ different MiPHY inside the same SoC.
+- st,sata_gen : to select which SATA_SPDMODE has to be set in the SATA system config
+ register.
+- st,px_rx_pol_inv : to invert polarity of RXn/RXp (respectively negative line and positive
+ line).
+- st,scc-on : enable ssc to reduce effects of EMI (only for sata or PCIe).
+- st,tx-impedance-comp : to compensate tx impedance avoiding out of range values.
+
+example:
+
+ miphy28lp_phy: miphy28lp@9b22000 {

+MediaTek Universal Flash Storage (UFS) M-PHY binding
+--------------------------------------------------------
+
+UFS M-PHY nodes are defined to describe on-chip UFS M-PHY hardware macro.
+Each UFS M-PHY node should have its own node.
+
+To bind UFS M-PHY with UFS host controller, the controller node should
+contain a phandle reference to UFS M-PHY node.
+
+Required properties for UFS M-PHY nodes:
+- compatible : Compatible list, contains the following controller:
+ "mediatek,mt8183-ufsphy" for ufs phy
+ persent on MT81xx chipsets.
+- reg : Address and length of the UFS M-PHY register set.
+- #phy-cells : This property shall be set to 0.
+- clocks : List of phandle and clock specifier pairs.
+- clock-names : List of clock input name strings sorted in the same
+ order as the clocks property. Following clocks are
+ mandatory.
+ "unipro": Unipro core control clock.
+ "mp": M-PHY core control clock.
+
+Example:
+
+ ufsphy: phy@11fa0000 {
+ compatible = "mediatek,mt8183-ufsphy";
+ reg = <0 0x11fa0000 0 0xc000>;

+Microsemi Ocelot SerDes muxing driver
+-------------------------------------
+
+On Microsemi Ocelot, there is a handful of registers in HSIO address
+space for setting up the SerDes to switch port muxing.
+
+A SerDes X can be "muxed" to work with switch port Y or Z for example.
+One specific SerDes can also be used as a PCIe interface.
+
+Hence, a SerDes represents an interface, be it an Ethernet or a PCIe one.
+
+There are two kinds of SerDes: SERDES1G supports 10/100Mbps in
+half/full-duplex and 1000Mbps in full-duplex mode while SERDES6G supports
+10/100Mbps in half/full-duplex and 1000/2500Mbps in full-duplex mode.
+
+Also, SERDES6G number (aka "macro") 0 is the only interface supporting
+QSGMII.
+
+This is a child of the HSIO syscon ("mscc,ocelot-hsio", see
+Documentation/devicetree/bindings/mips/mscc.txt) on the Microsemi Ocelot.
+
+Required properties:
+
+- compatible: should be "mscc,vsc7514-serdes"
+- #phy-cells : from the generic phy bindings, must be 2.
+ The first number defines the input port to use for a given
+ SerDes macro. The second defines the macro to use. They are
+ defined in dt-bindings/phy/phy-ocelot-serdes.h
+
+Example:
+
+ serdes: serdes {
+ compatible = "mscc,vsc7514-serdes";
+ #phy-cells = <2>;
+ };
+

+* Renesas R-Car generation 2 USB PHY
+
+This file provides information on what the device node for the R-Car generation
+2 USB PHY contains.
+
+Required properties:
+- compatible: "renesas,usb-phy-r8a7742" if the device is a part of R8A7742 SoC.
+ "renesas,usb-phy-r8a7743" if the device is a part of R8A7743 SoC.
+ "renesas,usb-phy-r8a7744" if the device is a part of R8A7744 SoC.
+ "renesas,usb-phy-r8a7745" if the device is a part of R8A7745 SoC.
+ "renesas,usb-phy-r8a77470" if the device is a part of R8A77470 SoC.
+ "renesas,usb-phy-r8a7790" if the device is a part of R8A7790 SoC.
+ "renesas,usb-phy-r8a7791" if the device is a part of R8A7791 SoC.
+ "renesas,usb-phy-r8a7794" if the device is a part of R8A7794 SoC.
+ "renesas,rcar-gen2-usb-phy" for a generic R-Car Gen2 or
+ RZ/G1 compatible device.
+
+ When compatible with the generic version, nodes must list the
+ SoC-specific version corresponding to the platform first
+ followed by the generic version.
+
+- reg: offset and length of the register block.
+- #address-cells: number of address cells for the USB channel subnodes, must
+ be <1>.
+- #size-cells: number of size cells for the USB channel subnodes, must be <0>.
+- clocks: clock phandle and specifier pair.
+- clock-names: string, clock input name, must be "usbhs".
+
+The USB PHY device tree node should have the subnodes corresponding to the USB
+channels. These subnodes must contain the following properties:
+- reg: the USB controller selector; see the table below for the values.
+- #phy-cells: see phy-bindings.txt in the same directory, must be <1>.
+
+The phandle's argument in the PHY specifier is the USB controller selector for
+the USB channel other than r8a77470 SoC; see the selector meanings below:
+
++-----------+---------------+---------------+
+|\ Selector | | |
++ --------- + 0 | 1 |
+| Channel \| | |
++-----------+---------------+---------------+
+| 0 | PCI EHCI/OHCI | HS-USB |
+| 2 | PCI EHCI/OHCI | xHCI |
++-----------+---------------+---------------+
+
+For r8a77470 SoC;see the selector meaning below:
+
++-----------+---------------+---------------+
+|\ Selector | | |
++ --------- + 0 | 1 |
+| Channel \| | |
++-----------+---------------+---------------+
+| 0 | EHCI/OHCI | HS-USB |

+ - "samsung,exynos5420-mipi-video-phy"
+ - "samsung,exynos5433-mipi-video-phy"
+- #phy-cells : from the generic phy bindings, must be 1;

+ - samsung,cam1-sysreg - phandle to the CAM1 system registers controller
+
+For "samsung,s5pv210-mipi-video-phy" compatible PHYs the second cell in
+the PHY specifier identifies the PHY and its meaning is as follows:
+ 0 - MIPI CSIS 0,
+ 1 - MIPI DSIM 0,
+ 2 - MIPI CSIS 1,
+ 3 - MIPI DSIM 1.
+"samsung,exynos5420-mipi-video-phy" and "samsung,exynos5433-mipi-video-phy"

+ - "samsung,exynos5420-dp-video-phy"
+- samsung,pmu-syscon: phandle for PMU system controller interface, used to
+ control pmu registers for power isolation.
+- #phy-cells : from the generic PHY bindings, must be 0;
+
+Samsung S5P/Exynos SoC series USB PHY
+-------------------------------------------------
+
+Required properties:
+- compatible : should be one of the listed compatibles:
+ - "samsung,exynos3250-usb2-phy"
+ - "samsung,exynos4210-usb2-phy"
+ - "samsung,exynos4x12-usb2-phy"
+ - "samsung,exynos5250-usb2-phy"
+ - "samsung,s5pv210-usb2-phy"
+- reg : a list of registers used by phy driver
+ - first and obligatory is the location of phy modules registers
+- samsung,sysreg-phandle - handle to syscon used to control the system registers
+- samsung,pmureg-phandle - handle to syscon used to control PMU registers
+- #phy-cells : from the generic phy bindings, must be 1;
+- clocks and clock-names:
+ - the "phy" clock is required by the phy module, used as a gate
+ - the "ref" clock is used to get the rate of the clock provided to the
+ PHY module
+
+Optional properties:
+- vbus-supply: power-supply phandle for vbus power source
+
+The first phandle argument in the PHY specifier identifies the PHY, its
+meaning is compatible dependent. For the currently supported SoCs (Exynos 4210
+and Exynos 4212) it is as follows:
+ 0 - USB device ("device"),
+ 1 - USB host ("host"),
+ 2 - HSIC0 ("hsic0"),
+ 3 - HSIC1 ("hsic1"),
+Exynos3250 has only USB device phy available as phy 0.
+
+Exynos 4210 and Exynos 4212 use mode switching and require that mode switch
+register is supplied.
+
+Example:
+
+For Exynos 4412 (compatible with Exynos 4212):
+
+usbphy: phy@125b0000 {
+ compatible = "samsung,exynos4x12-usb2-phy";
+ reg = <0x125b0000 0x100>;
+ clocks = <&clock 305>, <&clock 2>;
+ clock-names = "phy", "ref";
+ #phy-cells = <1>;
+ samsung,sysreg-phandle = <&sys_reg>;
+ samsung,pmureg-phandle = <&pmu_reg>;
+};
+
+Then the PHY can be used in other nodes such as:
+
+phy-consumer@12340000 {
+ phys = <&usbphy 2>;
+ phy-names = "phy";
+};
+
+Refer to DT bindings documentation of particular PHY consumer devices for more
+information about required PHYs and the way of specification.
+
+Samsung SATA PHY Controller
+---------------------------
+
+SATA PHY nodes are defined to describe on-chip SATA Physical layer controllers.
+Each SATA PHY controller should have its own node.
+
+Required properties:
+- compatible : compatible list, contains "samsung,exynos5250-sata-phy"
+- reg : offset and length of the SATA PHY register set;
+- #phy-cells : must be zero
+- clocks : must be exactly one entry
+- clock-names : must be "sata_phyctrl"
+- samsung,exynos-sataphy-i2c-phandle : a phandle to the I2C device, no arguments
+- samsung,syscon-phandle : a phandle to the PMU system controller, no arguments
+
+Example:
+ sata_phy: sata-phy@12170000 {
+ compatible = "samsung,exynos5250-sata-phy";
+ reg = <0x12170000 0x1ff>;
+ clocks = <&clock 287>;
+ clock-names = "sata_phyctrl";
+ #phy-cells = <0>;
+ samsung,exynos-sataphy-i2c-phandle = <&sata_phy_i2c>;
+ samsung,syscon-phandle = <&pmu_syscon>;
+ };
+
+Device-Tree bindings for sataphy i2c client driver
+--------------------------------------------------
+
+Required properties:
+compatible: Should be "samsung,exynos-sataphy-i2c"
+- reg: I2C address of the sataphy i2c device.
+
+Example:
+
+ sata_phy_i2c:sata-phy@38 {
+ compatible = "samsung,exynos-sataphy-i2c";
+ reg = <0x38>;
+ };
+
+Samsung Exynos5 SoC series USB DRD PHY controller
+--------------------------------------------------
+
+Required properties:
+- compatible : Should be set to one of the following supported values:
+ - "samsung,exynos5250-usbdrd-phy" - for exynos5250 SoC,
+ - "samsung,exynos5420-usbdrd-phy" - for exynos5420 SoC.
+ - "samsung,exynos5433-usbdrd-phy" - for exynos5433 SoC.
+ - "samsung,exynos7-usbdrd-phy" - for exynos7 SoC.
+- reg : Register offset and length of USB DRD PHY register set;
+- clocks: Clock IDs array as required by the controller
+- clock-names: names of clocks correseponding to IDs in the clock property;
+ Required clocks:
+ - phy: main PHY clock (same as USB DRD controller i.e. DWC3 IP clock),
+ used for register access.
+ - ref: PHY's reference clock (usually crystal clock), used for
+ PHY operations, associated by phy name. It is used to
+ determine bit values for clock settings register.
+ For Exynos5420 this is given as 'sclk_usbphy30' in CMU.
+ - optional clocks: Exynos5433 & Exynos7 SoC has now following additional
+ gate clocks available:
+ - phy_pipe: for PIPE3 phy
+ - phy_utmi: for UTMI+ phy
+ - itp: for ITP generation
+- samsung,pmu-syscon: phandle for PMU system controller interface, used to
+ control pmu registers for power isolation.
+- #phy-cells : from the generic PHY bindings, must be 1;
+
+For "samsung,exynos5250-usbdrd-phy" and "samsung,exynos5420-usbdrd-phy"
+compatible PHYs, the second cell in the PHY specifier identifies the
+PHY id, which is interpreted as follows:
+ 0 - UTMI+ type phy,
+ 1 - PIPE3 type phy,
+
+Example:
+ usbdrd_phy: usbphy@12100000 {

+- aliases: For SoCs like Exynos5420 having multiple USB 3.0 DRD PHY controllers,
+ 'usbdrd_phy' nodes should have numbered alias in the aliases node,
+ in the form of usbdrdphyN, N = 0, 1... (depending on number of
+ controllers).
+Example:
+ aliases {
+ usbdrdphy0 = &usb3_phy0;
+ usbdrdphy1 = &usb3_phy1;
+ };
+
+Samsung Exynos SoC series PCIe PHY controller
+--------------------------------------------------
+Required properties:
+- compatible : Should be set to "samsung,exynos5440-pcie-phy"
+- #phy-cells : Must be zero
+- reg : a register used by phy driver.
+ - First is for phy register, second is for block register.
+- reg-names : Must be set to "phy" and "block".
+
+Example:
+ pcie_phy0: pcie-phy@270000 {
+ #phy-cells = <0>;
+ compatible = "samsung,exynos5440-pcie-phy";
+ reg = <0x270000 0x1000>, <0x271000 0x40>;

+TI AM654 SERDES
+
+Required properties:
+ - compatible: Should be "ti,phy-am654-serdes"
+ - reg : Address and length of the register set for the device.
+ - #phy-cells: determine the number of cells that should be given in the
+ phandle while referencing this phy. Should be "2". The 1st cell
+ corresponds to the phy type (should be one of the types specified in
+ include/dt-bindings/phy/phy.h) and the 2nd cell should be the serdes
+ lane function.
+ If SERDES0 is referenced 2nd cell should be:
+ 0 - USB3
+ 1 - PCIe0 Lane0
+ 2 - ICSS2 SGMII Lane0
+ If SERDES1 is referenced 2nd cell should be:
+ 0 - PCIe1 Lane0
+ 1 - PCIe0 Lane1
+ 2 - ICSS2 SGMII Lane1
+ - power-domains: As documented by the generic PM domain bindings in
+ Documentation/devicetree/bindings/power/power_domain.txt.
+ - clocks: List of clock-specifiers representing the input to the SERDES.
+ Should have 3 items representing the left input clock, external
+ reference clock and right input clock in that order.
+ - clock-output-names: List of clock names for each of the clock outputs of
+ SERDES. Should have 3 items for CMU reference clock,
+ left output clock and right output clock in that order.
+ - assigned-clocks: As defined in
+ Documentation/devicetree/bindings/clock/clock-bindings.txt
+ - assigned-clock-parents: As defined in
+ Documentation/devicetree/bindings/clock/clock-bindings.txt
+ - #clock-cells: Should be <1> to choose between the 3 output clocks.
+ Defined in Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+ The following macros are defined in dt-bindings/phy/phy-am654-serdes.h
+ for selecting the correct reference clock. This can be used while
+ specifying the clocks created by SERDES.
+ => AM654_SERDES_CMU_REFCLK
+ => AM654_SERDES_LO_REFCLK
+ => AM654_SERDES_RO_REFCLK
+
+ - mux-controls: Phandle to the multiplexer that is used to select the lane
+ function. See #phy-cells above to see the multiplex values.
+
+Example:
+
+Example for SERDES0 is given below. It has 3 clock inputs;
+left input reference clock as indicated by <&k3_clks 153 4>, external
+reference clock as indicated by <&k3_clks 153 1> and right input
+reference clock as indicated by <&serdes1 AM654_SERDES_LO_REFCLK>. (The
+right input of SERDES0 is connected to the left output of SERDES1).
+
+SERDES0 registers 3 clock outputs as indicated in clock-output-names. The
+first refers to the CMU reference clock, second refers to the left output
+reference clock and the third refers to the right output reference clock.
+
+The assigned-clocks and assigned-clock-parents is used here to set the
+parent of left input reference clock to MAINHSDIV_CLKOUT4 and parent of
+CMU reference clock to left input reference clock.

+ TI am335x/am437x/dra7(am5)/dm814x CPSW3G Ethernet Subsystem supports
+ two 10/100/1000 Ethernet ports with selectable G/MII, RMII, and RGMII interfaces.
+ The interface mode is selected by configuring the MII mode selection register(s)
+ (GMII_SEL) in the System Control Module chapter (SCM). GMII_SEL register(s) and
+ bit fields placement in SCM are different between SoCs while fields meaning
+ is the same.
