David Wu a900152b5c pwm: rockchip: State of PWM clock should synchronize with PWM enabled state ... If the PWM was not enabled at U-Boot loader, PWM could not work for clock always disabled at PWM driver. The PWM clock is enabled at beginning of pwm_apply(), but disabled at end of pwm_apply(). If the PWM was enabled at U-Boot loader, PWM clock is always enabled unless closed by ATF. The pwm-backlight might turn off the power at early suspend, should disable PWM clock for saving power consume. It is important to provide opportunity to enable/disable clock at PWM driver, the PWM consumer should ensure correct order to call PWM enable and disable, and PWM driver ensure state of PWM clock synchronized with PWM enabled state.
