Hi,
This is an untested attempt to enable LPSS PWM in the driver. As part
of this did some restructuring for encapsulating the pwm_info inside the
panel->backlight itself. This makes enabling LPSS PWM clean and simple.

I did try it on my Asus T100 TAF without success.
The error in dmesg:
[=C2=A0=C2=A0=C2=A0 1.204866] [drm:pwm_setup_backlight [i915]] *ERROR* Failed to own the pwm chip: pwm_lpss

how can i further debug it for you?

Thanks
