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.

Changes since v1: - Use clamp() instead of two boundary checks
Nikita Travkin (4): clk: qcom: clk-rcg2: Fail Duty-Cycle configuration if MND divider is not enabled. clk: qcom: clk-rcg2: Make sure to not write d=0 to the NMD register pinctrl: qcom: msm8916: Allow CAMSS GP clocks to be muxed clk: qcom: gcc-msm8916: Add rates to the GP clocks
