I had my doubts whether simply clearing the PWMx_EN bit would be enough
to turn the PWM off but I stand corrected. It does work.
The added bonusu is that once without the invocations of {u,m}sleep and
clk_{enable_,disable_un}prepare, the sun4i_pwm_apply function finally
becomes safe for running in an atomic context.
I will therefore prepare a new patch and come back some time next week.
Have a great weekend,
Roman
