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