To handle resource sharing & IP integration 1. Rework on parent child relation between PWMSS and ECAP, EQEP & EHRPWM child devices to support runtime PM. 2. Add support for opt_clks in EHRPWM HWMOD entry to handle additional clock gating from control module. 3. Add HWMOD entries for EQEP PWM submodule. Signed-off-by: Philip, Avinash --- Changes since v1: - Remove ADDR_TYPE_RT for PWM sub module register entries. :100644 100644 ad8d43b... de2301c...
