	 * PWM users calling pwm_apply_args() expect to have a fresh config

	 * where the polarity and period are set according to pwm_args info.

	 * The problem is, polarity can only be changed when the PWM is

	 * disabled.

	 *

	 * PWM drivers supporting hardware readout may declare the PWM device

	 * as enabled, and prevent polarity setting, which changes from the

	 * existing behavior, where all PWM devices are declared as disabled

	 * at startup (even if they are actually enabled), thus authorizing

	 * polarity setting.

	 *

	 * To fulfill this requirement, we apply a new state which disables

	 * the PWM device and set the reference period and polarity config.

	 *

	 * Note that PWM users requiring a smooth handover between the

	 * bootloader and the kernel (like critical regulators controlled by

	 * PWM devices) will have to switch to the atomic API and avoid calling

	 * pwm_apply_args().
