Device Tree Clock bindings for arch-moxart This binding uses the common clock binding[1]. [1] Documentation/devicetree/bindings/clock/clock-bindings.txt MOXA ART SoCs allow to determine PLL output and APB frequencies by reading registers holding multiplier and divisor information. PLL: Required properties: - compatible : Must be "moxa,moxart-pll-clock" - #clock-cells : Should be 0 - reg : Should contain registers location and length - clocks : Should contain phandle + clock-specifier for the parent clock Optional properties: - clock-output-names : Should contain clock name APB: Required properties: - compatible : Must be "moxa,moxart-apb-clock" - #clock-cells : Should be 0 - reg : Should contain registers location and length - clocks : Should contain phandle + clock-specifier for the parent clock Optional properties: - clock-output-names : Should contain clock name For example: clk_pll: clk_pll@98100000 { compatible = "moxa,moxart-pll-clock"; #clock-cells = <0>; reg = <0x98100000 0x34>; }; clk_apb: clk_apb@98100000 { compatible = "moxa,moxart-apb-clock"; #clock-cells = <0>; reg = <0x98100000 0x34>; clocks = <&clk_pll>; };
