+Binding for TI DA8XX/OMAP-L13X/AM17XX/AM18XX CFGCHIP clocks
+
+TI DA8XX/OMAP-L13X/AM17XX/AM18XX SoCs contain a general purpose set of
+registers call CFGCHIPn. Some of these registers function as clock
+gates. This document describes the bindings for those clocks.
+
+All of the clock nodes described below must be child nodes of a CFGCHIP node
+(compatible = "ti,da830-cfgchip").

+- compatible: shall be "ti,da830-usb-phy-clocks".
+- #clock-cells: from common clock binding; shall be set to 1.
+- clocks: phandles to the parent clocks corresponding to clock-names
+- clock-names: shall be "fck", "usb_refclkin", "auxclk"

+This node provides two clocks. The clock at index 0 is the USB 2.0 PHY 48MHz
+clock and the clock at index 1 is the USB 1.1 PHY 48MHz clock.

+Binding for TI DaVinci PLL Controllers
+
+The PLL provides clocks to most of the components on the SoC. In addition
+to the PLL itself, this controller also contains bypasses, gates, dividers,
+an multiplexers for various clock signals.
+
+Required properties:
+- compatible: shall be one of:
+ - "ti,da850-pll0" for PLL0 on DA850/OMAP-L138/AM18XX
+ - "ti,da850-pll1" for PLL1 on DA850/OMAP-L138/AM18XX
+- reg: physical base address and size of the controller's register area.
+- clocks: phandles corresponding to the clock names
+- clock-names: names of the clock sources - depends on compatible string
+ - for "ti,da850-pll0", shall be "clksrc", "extclksrc"
+ - for "ti,da850-pll1", shall be "clksrc"
+
+Optional properties:
+- ti,clkmode-square-wave: Indicates that the the board is supplying a square
+ wave input on the OSCIN pin instead of using a crystal oscillator.
+ This property is only valid when compatible = "ti,da850-pll0".
+
+
+Optional child nodes:
+
+pllout
+ Describes the main PLL clock output (before POSTDIV). The node name must
+ be "pllout".
+
+ Required properties:
+ - #clock-cells: shall be 0
+
+sysclk
+ Describes the PLLDIVn divider clocks that provide the SYSCLKn clock
+ domains. The node name must be "sysclk". Consumers of this node should
+ use "n" in "SYSCLKn" as the index parameter for the clock cell.
+
+ Required properties:
+ - #clock-cells: shall be 1
+
+auxclk
+ Describes the AUXCLK output of the PLL. The node name must be "auxclk".
+ This child node is only valid when compatible = "ti,da850-pll0".
+
+ Required properties:
+ - #clock-cells: shall be 0
+
+obsclk
+ Describes the OBSCLK output of the PLL. The node name must be "obsclk".
+
+ Required properties:
+ - #clock-cells: shall be 0
+

+Binding for TI DaVinci Power Sleep Controller (PSC)
+
+The PSC provides power management, clock gating and reset functionality. It is
+primarily used for clocking.
+
+Required properties:
+- compatible: shall be one of:
+ - "ti,da850-psc0" for PSC0 on DA850/OMAP-L138/AM18XX
+ - "ti,da850-psc1" for PSC1 on DA850/OMAP-L138/AM18XX
+- reg: physical base address and size of the controller's register area
+- #clock-cells: from common clock binding; shall be set to 1
+- #power-domain-cells: from generic power domain binding; shall be set to 1.
+- clocks: phandles to clocks corresponding to the clock-names property
+- clock-names: list of parent clock names - depends on compatible value
+ - for "ti,da850-psc0", shall be "pll0_sysclk1", "pll0_sysclk2",
+ "pll0_sysclk4", "pll0_sysclk6", "async1"
+ - for "ti,da850-psc1", shall be "pll0_sysclk2", "pll0_sysclk4", "async3"
+
+Optional properties:
+- #reset-cells: from reset binding; shall be set to 1 - only applicable when
+ at least one local domain provides a local reset.
+
+Consumers:
+
+ Clock, power domain and reset consumers shall use the local power domain
+ module ID (LPSC) as the index corresponding to the clock cell. Refer to
+ the device-specific datasheet to find these numbers. NB: Most local
+ domains only provide a clock/power domain and not a reset.
