-Device Tree Clock bindings for arch-at91
-
-This binding uses the common clock binding[1].

-
-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";
