-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>;
- };
