This patch series adds the support for 1. In am33xx SoC[1], enhanced capture (eCAP) supports auxiliary PWM (APWM). This series adds the PWM driver support for the APWM feature for eCAP on AM33xx. AM335X_ECAP0_IN_PWM0_OUT is used to enable the backlight.
2. Enable eCAP0 PWM and LCD pin muxing to support splash screen on AM335x EVM[2]. 3. Add lcdc, panel and backlight nodes for AM335x EVM. This series doesn't contain defconfig changes since we don't want to enable LCD, splash screen and PWM support by default. Enabling splash screen and PWM support in defconfig causes u-boot crash on AM335x based beaglebone black. This will be handled in a separate patch.
