ECAP hardware on AM33XX SOC supports auxiliary PWM (APWM) feature. This commit adds PWM driver support for ECAP hardware on AM33XX SOC. In the ECAP hardware, each PWM pin can also be configured to be in capture mode. Current implementation only supports PWM mode of operation. Also, hardware supports sync between multiple PWM pins but the driver supports simple independent PWM functionality.
