One comment to consider, though. There are three channels in that PWM AFAIU.
One of them is backlight control, another one can be attached to haptics. The
concern is how this series may (or may not?) affect haptics behaviour.
When you say "in that PWM" do you mean the LPSS one or the CRC one ?
CRC one. I have read it from PMIC spec, that's why the question.
Ah I see, well the kernel driver only implements support for 1 PWM output,
the one which is used for the backlight brighness control.
So this series should not affect haptics behavior, since it looks like
the haptic functionality is not supported in the mainline kernel at all.
And I'm also not aware of any tablets with a CRC PMIC which have
(non working) haptic support.
