Subject: [PATCH 7/8] ARM: dts: AM33XX: Add PWMSS device tree nodes
Add PWMSS device tree nodes in relation with ECAP & EHRPWM DT nodes to
AM33XX SoC family. Also populates device tree nodes for ECAP & EHRPWM by
adding necessary properties like pwm-cells, base reg & set disabled as
status.
Signed-off-by: Philip, Avinash <avinashphilip@...com>

Second version
- Combined with HWMOD changes & DT bindings.
- Handling Parent<-> child relation ship for PWM subsystem
