Christophe JAILLET	2b8e30b1bd	pwm: clk: Use the devm_clk_get_prepared() helper function ... Use the devm_clk_get_prepared() helper function instead of hand-writing it. It saves some line of codes.

Uwe Kleine-König	d5806ac636	pwm: clk: Convert to platform remove callback returning void ... The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

Nikita Travkin	901f8f5404	pwm: Add clock based PWM output driver ... Some systems have clocks exposed to external devices. If the clock controller supports duty-cycle configuration, such clocks can be used as pwm outputs. In fact PWM and CLK subsystems are interfaced with in a similar way and an "opposite" driver already exists (clk-pwm). Add a driver that would enable pwm devices to be used via clk subsystem.
