+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").
+
+USB PHY clocks
+--------------
+Required properties:
+- 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.
+
+eHRPWM Time Base Clock (TBCLK)
+------------------------------
+Required properties:
+- compatible: shall be "ti,da830-tbclksync".
+- #clock-cells: from common clock binding; shall be set to 0.
+- clocks: phandle to the parent clock
+- clock-names: shall be "fck"
+
+PLL DIV4.5 divider
+------------------
+Required properties:
+- compatible: shall be "ti,da830-div4p5ena".
+- #clock-cells: from common clock binding; shall be set to 0.
+- clocks: phandle to the parent clock
+- clock-names: shall be "pll0_pllout"
+
+EMIFA clock source (ASYNC1)
+---------------------------
+Required properties:
+- compatible: shall be "ti,da850-async1-clksrc".
+- #clock-cells: from common clock binding; shall be set to 0.
+- clocks: phandles to the parent clocks corresponding to clock-names
+- clock-names: shall be "pll0_sysclk3", "div4.5"
+
+ASYNC3 clock source
+-------------------
+Required properties:
+- compatible: shall be "ti,da850-async3-clksrc".
+- #clock-cells: from common clock binding; shall be set to 0.
+- clocks: phandles to the parent clocks corresponding to clock-names
+- clock-names: shall be "pll0_sysclk2", "pll1_sysclk2"
+
+Examples:

+ compatible = "ti,da830-cfgchip", "syscon", "simple-mfd";
+ reg = <0x1417c 0x14>;

+ #clock-cells = <1>;
+ clocks = <&psc1 1>, <&usb_refclkin>, <&pll0_auxclk>;
+ clock-names = "fck", "usb_refclkin", "auxclk";
+ };
+ ehrpwm_tbclk: ehrpwm_tbclk {
+ compatible = "ti,da830-tbclksync";
+ #clock-cells = <0>;
+ clocks = <&psc1 17>;
+ clock-names = "fck";
+ };
+ div4p5_clk: div4.5 {
+ compatible = "ti,da830-div4p5ena";
+ #clock-cells = <0>;
+ clocks = <&pll0_pllout>;
+ clock-names = "pll0_pllout";
+ };
+ async1_clk: async1 {
+ compatible = "ti,da850-async1-clksrc";
+ #clock-cells = <0>;
+ clocks = <&pll0_sysclk 3>, <&div4p5_clk>;
+ clock-names = "pll0_sysclk3", "div4.5";
+ };
+ async3_clk: async3 {
+ compatible = "ti,da850-async3-clksrc";
+ #clock-cells = <0>;
+ clocks = <&pll0_sysclk 2>, <&pll1_sysclk 2>;
+ clock-names = "pll0_sysclk2", "pll1_sysclk2";
