Device Tree Clock bindings for arch-at91 This binding uses the common clock binding[1]. [1] Documentation/devicetree/bindings/clock/clock-bindings.txt Slow Clock controller: Required properties: - compatible : shall be one of the following: "atmel,at91sam9x5-sckc", "atmel,sama5d3-sckc", "atmel,sama5d4-sckc" or "microchip,sam9x60-sckc": at91 SCKC (Slow Clock Controller) - #clock-cells : shall be 1 for "microchip,sam9x60-sckc" otherwise shall be 0. - clocks : shall be the input parent clock phandle for the clock. Optional properties: - atmel,osc-bypass : boolean property. Set this when a clock signal is directly provided on XIN. For example: sckc@fffffe50 { compatible = "atmel,at91sam9x5-sckc"; reg = <0xfffffe50 0x4>; clocks = <&slow_xtal>; #clock-cells = <0>; }; Power Management Controller (PMC): Required properties: - compatible : shall be "atmel,-pmc", "syscon" or "microchip,sam9x60-pmc" can be: at91rm9200, at91sam9260, at91sam9261, at91sam9263, at91sam9g45, at91sam9n12, at91sam9rl, at91sam9g15, at91sam9g25, at91sam9g35, at91sam9x25, at91sam9x35, at91sam9x5, sama5d2, sama5d3 or sama5d4. - #clock-cells : from common clock binding; shall be set to 2. The first entry is the type of the clock (core, system, peripheral or generated) and the second entry its index as provided by the datasheet - clocks : Must contain an entry for each entry in clock-names. - clock-names: Must include the following entries: "slow_clk", "main_xtal" Optional properties: - atmel,osc-bypass : boolean property. Set this when a clock signal is directly provided on XIN. For example: pmc: pmc@f0018000 { compatible = "atmel,sama5d4-pmc", "syscon"; reg = <0xf0018000 0x120>; interrupts = <1 IRQ_TYPE_LEVEL_HIGH 7>; #clock-cells = <2>; clocks = <&clk32k>, <&main_xtal>; clock-names = "slow_clk", "main_xtal"; };
