    Hello

    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:

    [    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
