The grf property is not part of the pwm binding and I remember
this coming up in veyron times, when Thiery didn't want such settings
in the pwm driver. So the kernel pwm driver does not switch anything
right now.

No it doesn't. The tsadc on rk3288 does not do any grf settings right now,
as it is using the v2_initialize function. Only rk3366 and rk3399 seem
to do any grf settings in the current v4.12-rc1 . Or is there some tsadc
patch from you pending to change that?
