1STMicroelectronics PWM driver bindings
2--------------------------------------
3
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: 		Valid entries are "pwm" and/or "capture".
17- clocks: 		phandle of the clock used by the PWM module.
18			For Clk properties, please refer to [2].
19- interrupts:		IRQ for the Capture device
20
21Optional properties:
22- st,pwm-num-chan:	Number of available PWM channels.  Default is 0.
23- st,capture-num-chan:	Number of available Capture channels.  Default is 0.
