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. > And tsadc uses it to shutdown the system. 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? Heiko
