For example:

	sckc: sckc@fffffe50 {

		compatible = "atmel,sama5d3-pmc";

		reg = <0xfffffe50 0x4>

		#size-cells = <0>;

		#address-cells = <1>;

		/* put at91 slow clocks here */

	};

Required properties for internal slow RC oscillator:

- #clock-cells : from common clock binding; shall be set to 0.

- clock-frequency : define the internal RC oscillator frequency.

Optional properties:

- clock-accuracy : define the internal RC oscillator accuracy.

For example:

	slow_rc_osc: slow_rc_osc {

		clock-frequency = <32768>;

		clock-accuracy = <50000000>;

	};

Required properties for slow oscillator:

- #clock-cells : from common clock binding; shall be set to 0.

- clocks : shall encode the main osc source clk sources (see atmel datasheet).

Optional properties:

- atmel,osc-bypass : boolean property. Set this when a clock signal is directly

  provided on XIN.

For example:

	slow_osc: slow_osc {

		compatible = "atmel,at91rm9200-clk-slow-osc";

		#clock-cells = <0>;

		clocks = <&slow_xtal>;

	};

Required properties for slow clock:

- #clock-cells : from common clock binding; shall be set to 0.

- clocks : shall encode the slow clk sources (see atmel datasheet).

For example:

	clk32k: slck {

		compatible = "atmel,at91sam9x5-clk-slow";

		#clock-cells = <0>;

		clocks = <&slow_rc_osc &slow_osc>;

	};

Required properties for PMC node:

- reg : defines the IO memory reserved for the PMC.

- #size-cells : shall be 0 (reg is used to encode clk id).

		/* put at91 clocks here */

	};

Required properties for main clock internal RC oscillator:

- interrupt-parent : must reference the PMC node.

- interrupts : shall be set to "<0>".

- clock-frequency : define the internal RC oscillator frequency.

Optional properties:

- clock-accuracy : define the internal RC oscillator accuracy.

For example:

	main_rc_osc: main_rc_osc {

		compatible = "atmel,at91sam9x5-clk-main-rc-osc";

		interrupt-parent = <&pmc>;

		interrupts = <0>;

		clock-frequency = <12000000>;

		clock-accuracy = <50000000>;

	};

Required properties for main clock oscillator:

- interrupt-parent : must reference the PMC node.

- interrupts : shall be set to "<0>".

- #clock-cells : from common clock binding; shall be set to 0.

- clocks : shall encode the main osc source clk sources (see atmel datasheet).

Optional properties:

- atmel,osc-bypass : boolean property. Specified if a clock signal is provided

  on XIN.

  clock signal is directly provided on XIN pin.

For example:

	main_osc: main_osc {

		compatible = "atmel,at91rm9200-clk-main-osc";

		interrupt-parent = <&pmc>;

		interrupts = <0>;

		#clock-cells = <0>;

		clocks = <&main_xtal>;

	};

Required properties for main clock:

- interrupt-parent : must reference the PMC node.

- interrupts : shall be set to "<0>".

- #clock-cells : from common clock binding; shall be set to 0.

- clocks (optional if clock-frequency is provided) : shall be the slow clock

	phandle. This clock is used to calculate the main clock rate if

	"clock-frequency" is not provided.

- clock-frequency : the main oscillator frequency.Prefer the use of

	"clock-frequency" over automatic clock rate calculation.

- clocks : shall encode the main clk sources (see atmel datasheet).

For example:

	main: mainck {

		compatible = "atmel,at91rm9200-clk-main";

		compatible = "atmel,at91sam9x5-clk-main";

		interrupt-parent = <&pmc>;
