This patch 1. Add support for device-tree binding for ECAP APWM driver. 2. Set size of pwm-cells set to 3 to support PWM channel number, PWM period & polarity configuration from device tree. 3. Add enable/disable clock gating in PWM subsystem common config space. 4. When here set .owner member in platform_driver structure to THIS_MODULE.

Make sure the duty-cycle and period passed in are not negative. This should eventually be made implicit by making them unsigned. While at it, the drivers' .config() implementations can have the equivalent checks removed.

APWM mode is enabled while configuring PWM device. This was done to handle shadow & immediate mode update of period and compare registers. However, leaving it enabled after configuring will cause APWM output on PWM pin even before enabling PWM device. Fix the same by disabling APWM mode after configuring if PWM device is not running.

The implementation in devm_request_and_ioremap() already shows error message, so no need to show dev_err again if devm_request_and_ioremap() fails.

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.
