--- Comment #34 from Shobhit <shobhit.kumar at intel.com> ---
This will happen because this device as I remember from previous discussions
uses LPSS for backlight and not PMIC and the PMIC device also might be
different and the ACPI enumeration for the same might not be available. Hence
it is likely that the we will not get the gpio and pwn chips. Today the PWM
supported is only for CRC PMIC which is not there on this platform. There needs
to be some work done to use LPSS based PWM. That driver is already there in the
kernel. Plumbing in i915 PWM support is pending.
