+
+	  This framework is designed to provide a generic interface for PHY
+	  devices present in the kernel. This layer will have the generic
+	  API by which phy drivers can create PHY using the phy framework and
+	  phy users can obtain reference to the PHY. All the users of this
+	  framework should select this config.

+      Say 'Y' here to add support for MediaTek T-PHY driver,
+      it supports multiple usb2.0, usb3.0 ports, PCIe and
+	  SATA, and meanwhile supports two version T-PHY which have
+	  different banks layout, the T-PHY with shared banks between
+	  multi-ports is first version, otherwise is second veriosn,
+	  so you can easily distinguish them by banks layout.

+	  USB3.1 GEN2 controllers on MediaTek chips. The driver supports
+	  multiple USB2.0, USB3.1 GEN2 ports.

+ * The APM X-Gene PHY consists of two PLL clock macro's (CMU) and lanes.
+ * The first PLL clock macro is used for internal reference clock. The second
+ * PLL clock macro is used to generate the clock for the PHY. This driver
+ * configures the first PLL CMU, the second PLL CMU, and programs the PHY to
+ * operate according to the mode of operation. The first PLL CMU is only
+ * required if internal clock is enabled.
+ *
+ * Logical Layer Out Of HW module units:
+ *
+ * -----------------
+ * | Internal      |    |------|
+ * | Ref PLL CMU   |----|      |     -------------    ---------
+ * ------------ ----    | MUX  |-----|PHY PLL CMU|----| Serdes|
+ *                      |      |     |           |    ---------
+ * External Clock ------|      |     -------------
+ *                      |------|
+ *
+ * The Ref PLL CMU CSR (Configuration System Registers) is accessed
+ * indirectly from the SDS offset at 0x2000. It is only required for
+ * internal reference clock.
+ * The PHY PLL CMU CSR is accessed indirectly from the SDS offset at 0x0000.
+ * The Serdes CSR is accessed indirectly from the SDS offset at 0x0400.
+ *
+ * The Ref PLL CMU can be located within the same PHY IP or outside the PHY IP
+ * due to shared Ref PLL CMU. For PHY with Ref PLL CMU shared with another IP,
+ * it is located outside the PHY IP. This is the case for the PHY located
+ * at 0x1f23a000 (SATA Port 4/5). For such PHY, another resource is required
+ * to located the SDS/Ref PLL CMU module and its clock for that IP enabled.
+ *
+ * Currently, this driver only supports Gen3 SATA mode with external clock.

+ *
+ * The ROCKCHIP Type-C PHY has two PLL clocks. The first PLL clock
+ * is used for USB3, the second PLL clock is used for DP. This Type-C PHY has
+ * 3 working modes: USB3 only mode, DP only mode, and USB3+DP mode.
+ * At USB3 only mode, both PLL clocks need to be initialized, this allows the
+ * PHY to switch mode between USB3 and USB3+DP, without disconnecting the USB
+ * device.
+ * In The DP only mode, only the DP PLL needs to be powered on, and the 4 lanes
+ * are all used for DP.
+ *
+ * This driver gets extcon cable state and property, then decides which mode to
+ * select:
+ *
+ * 1. USB3 only mode:
+ *    EXTCON_USB or EXTCON_USB_HOST state is true, and
+ *    EXTCON_PROP_USB_SS property is true.
+ *    EXTCON_DISP_DP state is false.
+ *
+ * 2. DP only mode:
+ *    EXTCON_DISP_DP state is true, and
+ *    EXTCON_PROP_USB_SS property is false.
+ *    If EXTCON_USB_HOST state is true, it is DP + USB2 mode, since the USB2 phy
+ *    is a separate phy, so this case is still DP only mode.
+ *
+ * 3. USB3+DP mode:
+ *    EXTCON_USB_HOST and EXTCON_DISP_DP are both true, and
+ *    EXTCON_PROP_USB_SS property is true.
+ *
+ * This Type-C PHY driver supports normal and flip orientation. The orientation
+ * is reported by the EXTCON_PROP_USB_TYPEC_POLARITY property: true is flip
+ * orientation, false is normal orientation.
