* ARM Primecell Peripherals

ARM, Ltd. Primecell peripherals have a standard id register that can be used to

identify the peripheral type, vendor, and revision. This value can be used for

driver matching.

Required properties:

- compatible : should be a specific name for the peripheral and

               "arm,primecell".  The specific name will match the ARM

               engineering name for the logic block in the form: "arm,pl???"

Optional properties:

- arm,primecell-periphid : Value to override the h/w value with

- clocks : From common clock binding. First clock is phandle to clock for apb

	pclk. Additional clocks are optional and specific to those peripherals.

- clock-names : From common clock binding. Shall be "apb_pclk" for first clock.

- dmas : From common DMA binding. If present, refers to one or more dma channels.

- dma-names : From common DMA binding, needs to match the 'dmas' property.

              Devices with exactly one receive and transmit channel shall name

              these "rx" and "tx", respectively.

- pinctrl-<n> : Pinctrl states as described in bindings/pinctrl/pinctrl-bindings.txt

- pinctrl-names : Names corresponding to the numbered pinctrl states

- interrupts : one or more interrupt specifiers

- interrupt-names : names corresponding to the interrupts properties

Example:

serial@fff36000 {

	compatible = "arm,pl011", "arm,primecell";

	arm,primecell-periphid = <0x00341011>;

	clocks = <&pclk>;

	clock-names = "apb_pclk";

	dmas = <&dma-controller 4>, <&dma-controller 5>;

	dma-names = "rx", "tx";	

	pinctrl-0 = <&uart0_default_mux>, <&uart0_default_mode>;

	pinctrl-1 = <&uart0_sleep_mode>;

	pinctrl-names = "default","sleep";

	interrupts = <0 11 0x4>;
