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.

config PWM_ROCKCHIP

bool "Enable support for the Rockchip PWM"
|
|
depends on DM_PWM
|
|
help
|
|
This PWM is found on RK3288 and other Rockchip SoCs. It supports a
|
|
programmable period and duty cycle. A 32-bit counter is used.
|
|
Various options provided in the hardware (such as capture mode and
|
|
continuous/single-shot) are not supported by the driver.
