| 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,<chip>-pmc", "syscon" or | |
| "microchip,sam9x60-pmc" | |
| <chip> 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"; | |
| }; |
