-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 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
-
-
-Examples:
-
-	pll0: clock-controller@11000 {
-		compatible = "ti,da850-pll0";
-		reg = <0x11000 0x1000>;
-		clocks = <&ref_clk>, <&pll1_sysclk 3>;
-		clock-names = "clksrc", "extclksrc";
-		ti,clkmode-square-wave;
-
-		pll0_pllout: pllout {
-			#clock-cells = <0>;
-		};
-
-		pll0_sysclk: sysclk {
-			#clock-cells = <1>;
-		};
-
-		pll0_auxclk: auxclk {
-			#clock-cells = <0>;
-		};
-
-		pll0_obsclk: obsclk {
-			#clock-cells = <0>;
-		};
-	};
-
-	pll1: clock-controller@21a000 {
-		compatible = "ti,da850-pll1";
-		reg = <0x21a000 0x1000>;
-		clocks = <&ref_clk>;
-		clock-names = "clksrc";
-
-		pll0_sysclk: sysclk {
-			#clock-cells = <1>;
-		};
-
-		pll0_obsclk: obsclk {
-			#clock-cells = <0>;
-		};
-	};
