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>; }; }; Also see: - Documentation/devicetree/bindings/clock/clock-bindings.txt |
