Subject: [PATCH v2 0/4] Prepare general purpose clocks on msm8916

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
