1STMicroelectronics PWM driver bindings
2--------------------------------------

4Required parameters:
5- compatible :		"st,pwm"
6- #pwm-cells : 		Number of cells used to specify a PWM. First cell
7			specifies the per-chip index of the PWM to use and the
8			second cell is the period in nanoseconds - fixed to 2
9			for STiH41x.
10- reg :			Physical base address and length of the controller's
11			registers.
12- pinctrl-names: 	Set to "default".
13- pinctrl-0: 		List of phandles pointing to pin configuration nodes
14			for PWM module.
15			For Pinctrl properties, please refer to [1].
16- clock-names: 		Set to "pwm".
17- clocks: 		phandle of the clock used by the PWM module.
18			For Clk properties, please refer to [2].
19
20Optional properties:
21- st,pwm-num-chan:	Number of available channels. If not passed, the driver
22			will consider single channel by default.

33	pinctrl-names = "default";
34	pinctrl-0 = <&pinctrl_pwm1_chan0_default
35		     &pinctrl_pwm1_chan1_default
36		     &pinctrl_pwm1_chan2_default
37		     &pinctrl_pwm1_chan3_default>;
38	clocks = <&clk_sysin>;
39	clock-names = "pwm";
40	st,pwm-num-chan = <4>;
