				2	bool "Enable support for pulse-width modulation devices (PWM)"
				3	depends on DM
				4	help
				5	A pulse-width modulator emits a pulse of varying width and provides
				6	control over the duty cycle (high and low time) of the signal. This
				7	is often used to control a voltage level. The more time the PWM
				8	spends in the 'high' state, the higher the voltage. The PWM's
				9	frequency/period can be controlled along with the proportion of that
				10	time that the signal is high.
