Hello Nikita,

This series introduces an "adapter" driver that allows PWM consumers
to control clock outputs with duty-cycle control.

Some platforms (e.g. some Qualcomm chipsets) have "General Purpose"
clocks that can be muxed to GPIO outputs and used as PWM outputs. 
Those outputs may be connected to various peripherals such as
leds in display backlight or haptic feedback motor driver. 

To avoid re-implementing every single PWM consumer driver with clk
support (like in [1]) and don't put the burden of providing the PWM
sources on the clock drivers (as was proposed in [2]), clk based
pwm controller driver is introduced.

There is an existing driver that provides the opposite function
in drivers/clk/clk-pwm.c with a compatible "pwm-clock" so the new
driver uses the opposite naming scheme: drivers/pwm/pwm-clk.c
and compatible "clk-pwm". 

You got some feedback on your patches and didn't respond to it. Are you
interested to improve your patch set? If yes, I'm willing to review more
deeply. If not, I'm not.

Best regards
Uwe
