    pwm: imx: Let PWM be active during suspend · 1f6eefeb
    Fabio Estevam authored
    On a imx6q-cubox-i board, which has an LED driven by PWM, when the system
    goes into suspend the PWM block is disabled by default, then the PWM pin
    goes to logic level zero and turn on the LED during suspend, which is not
    really the behaviour we want to see.
    
    By keeping the PWM enabled during suspend via STOPEN bit, the pwm-leds
    driver sets the brightness to zero in suspend and then the LED is
    turned off as expected.
    
    So always set the STOPEN to fix the PWM behaviour in suspend.
