[PATCH v4 09/11] ARM: dts: AM33XX: Add PWMSS device tree nodes

Wed Nov 21 08:11:06 EST 2012
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.
