<pre>@Shobhit: I've tested your patches on Dell Venue 8 Pro but it is not working.
Log shows:
[ 4.369291] [drm:intel_dsi_init [i915]] *ERROR* Failed to own gpio for panel
control
[ 4.369889] [drm:pwm_setup_backlight [i915]] *ERROR* Failed to own the pwm
chip
This is caused by the soc pmic driver loaded *after* i915, and that's why the
pwm list is empty when requesting it. I've added it directly to the kernel and
tested i915 as build-in and module, but it doesn't change the effect. Do you
have a helping hand?</pre>
