1 TI SOC based PWM Subsystem
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.
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.
16 Also child nodes should also populated under PWMSS DT node.
