Some devices make use of general purpose clocks as PWM outputs by controlling their duty cycle. Notably, many devices (e.g. Samsung A3/A5, LG G Watch R and probably many others) use clock based PWM to control the haptic feedback, some other can control backlight or flash/torch LED brightness. As a follow-up to a proposed clock based PWM output driver [1], this series contains various fixes to make it useful on msm8916 based devices.
