1 TI SOC based PWM Subsystem
4 - compatible: Must be "ti,<soc>-pwmss".
5 for am33xx - compatible = "ti,am33xx-pwmss";
6 for am4372 - compatible = "ti,am4372-pwmss","ti,am33xx-pwmss";
7 for dra746 - compatible = "ti,dra746-pwmss", "ti,am33xx-pwmss"
9 - reg: physical base address and size of the registers map.
10 - address-cells: Specify the number of u32 entries needed in child nodes.
12 - size-cells: specify number of u32 entries needed to specify child nodes size
13 in reg property. Should set to 1.
14 - ranges: describes the address mapping of a memory-mapped bus. Should set to
15 physical address map of child's base address, physical address within
16 parent's address space and length of the address map. For am33xx,
17 3 set of child register maps present, ECAP register space, EQEP
18 register space, EHRPWM register space.
20 Also child nodes should also populated under PWMSS DT node.
