dm: pwm: Add a PWM uclass Add a uclass that supports Pulse Width Modulation (PWM) devices. It provides methods to enable/disable and configure the device. Signed-off-by: Simon Glass <sjg@chromium.org>

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.
pwm: rockchip: Add a PWM driver for Rockchip SoCs Add a simple driver which implements the standard PWM uclass interface. Signed-off-by: Simon Glass <sjg@chromium.org>

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.
