1 * Rockchip Audio PWM controller
5 - compatible: "rockchip,audio-pwm-v1"
6 - reg: physical base address of the controller and length of memory mapped
8 - dmas: DMA specifiers for tx dma. See the DMA client binding,
10 - dma-names: should include "tx".
11 - clocks: a list of phandle + clock-specifer pairs, one for each entry in clock-names.
12 - clock-names: should contain following:
13    - "clk" : clock for Audio PWM controller
14    - "hclk": clock for AHB BUS
15 - pinctrl-names: Must contain a "default" entry.
16 - pinctrl-N: One property must exist for each entry in
17 	     pinctrl-names. See ../pinctrl/pinctrl-bindings.txt
22 - rockchip,sample-width-bits: Output sampling data width,the value ranges from 8 to 11 bits.
23 - rockchip,interpolat-points-cfg: Interpolation rate,the value must be 1/3/7/15 points,
25 - spk-ctl-gpios: The gpio of speak controller.
27 Example for Audio PWM controller:
30 	compatible = "rockchip,audio-pwm-v1";
33 	clock-names = "clk", "hclk";
35 	dma-names = "tx";
36 	pinctrl-names = "default";
37 	pinctrl-0 = <&audpwmm0_pins>;
38 	rockchip,sample-width-bits = <11>;
39 	rockchip,interpolat-points = <1>;
40 	spk-ctl-gpios = <&gpio0 RK_PC0 GPIO_ACTIVE_HIGH>;
