Are there any reviews on this patch series? This patch set is required for LCD backlight work based on ECAP PWM in am335x-evm & am335x-evmsk.

In AM33xx PWM sub modules like ECAP, EHRPWM EQEP are integrated to PWM subsystem. All these submodules shares the resources (clock) has a clock gating register in PWM Subsystem. So a parent PWM subsystem driver is created. To support PWM subsystem driver, parent child relation is created in HWMOD entry in patch #2. In addition EHRPWM module requires explicit clock gating from control module. Hence add clock node for tbclk handling in patch #4. Patch #3 to support common clock migration for AM33xx. Also Device tree nodes populated to support parent child relation between PWMSS, ECAP EHRPWM submodules (patch #5, 6 7). This patch series based on linux_omap/master [2] and tested for backlight with ECAP on AM335x-evm AM335x-evmsk. Are there any reviews on this patch series? This patch set is required for LCD backlight work based on ECAP PWM in am335x-evm am335x-evmsk.
