1TI SOC based PWM Subsystem
2
3Required properties:
4- compatible: Must be "ti,am33xx-pwmss";
5- reg: physical base address and size of the registers map.
6- address-cells: Specify the number of u32 entries needed in child nodes.
7		  Should set to 1.
8- size-cells: specify number of u32 entries needed to specify child nodes size
9		in reg property. Should set to 1.
10- ranges: describes the address mapping of a memory-mapped bus. Should set to
11	   physical address map of child's base address, physical address within
12	   parent's address  space and length of the address map. For am33xx,
13	   3 set of child register maps present, ECAP register space, EQEP
14	   register space, EHRPWM register space.
15
16Also child nodes should also populated under PWMSS DT node.

19pwmss0: pwmss@48300000 {
20	compatible = "ti,am33xx-pwmss";
21	reg = <0x48300000 0x10>;
22	ti,hwmods = "epwmss0";
23	#address-cells = <1>;
24	#size-cells = <1>;
25	status = "disabled";
26	ranges = <0x48300100 0x48300100 0x80   /* ECAP */
27		  0x48300180 0x48300180 0x80   /* EQEP */
28		  0x48300200 0x48300200 0x80>; /* EHRPWM */

30	/* child nodes go here */
