1* ARM Primecell Peripherals
2
3ARM, Ltd. Primecell peripherals have a standard id register that can be used to
4identify the peripheral type, vendor, and revision. This value can be used for
5driver matching.
6
7Required properties:
8
9- compatible : should be a specific name for the peripheral and
10               "arm,primecell".  The specific name will match the ARM
11               engineering name for the logic block in the form: "arm,pl???"
12
13Optional properties:
14
15- arm,primecell-periphid : Value to override the h/w value with
16- clocks : From common clock binding. First clock is phandle to clock for apb
17	pclk. Additional clocks are optional and specific to those peripherals.
18- clock-names : From common clock binding. Shall be "apb_pclk" for first clock.
19- dmas : From common DMA binding. If present, refers to one or more dma channels.
20- dma-names : From common DMA binding, needs to match the 'dmas' property.
21              Devices with exactly one receive and transmit channel shall name
22              these "rx" and "tx", respectively.
23- pinctrl-<n> : Pinctrl states as described in bindings/pinctrl/pinctrl-bindings.txt
24- pinctrl-names : Names corresponding to the numbered pinctrl states
25- interrupts : one or more interrupt specifiers
26- interrupt-names : names corresponding to the interrupts properties

30serial@fff36000 {
31	compatible = "arm,pl011", "arm,primecell";
32	arm,primecell-periphid = <0x00341011>;
33
34	clocks = <&pclk>;
35	clock-names = "apb_pclk";
36
37	dmas = <&dma-controller 4>, <&dma-controller 5>;
38	dma-names = "rx", "tx";
39
40	pinctrl-0 = <&uart0_default_mux>, <&uart0_default_mode>;
41	pinctrl-1 = <&uart0_sleep_mode>;
42	pinctrl-names = "default","sleep";
43
44	interrupts = <0 11 0x4>;
