Hello All,
Re: http://lists.freedesktop.org/archives/intel-gfx/2015-April/065313.html
Recently I noticed another device Dell Venue 8 Pro (BYT-CR) which
should be using LPSS backlight control. There is already a LPSS PWM
chip driver in upstream kernel which should be used in this case. That
patch is for another day
I would like to humbly register my interest in seeing this support
added in. I have a Dell Venue 8 Pro running Linux and I'd like to be
able to adjust the backlight.
Shobhit, any thoughts or news on LPSS backlight?
Yeah, this got sidelined by other stuff. Should be doable. Let me get
back onto this. Will surely need testing support as don't have this
device with me.

Shobhit
I also noticed vbetool dpms control doesn't work either; not sure
whether that's related?
It's expected vbetool does not work with i915. vbetool bypasses the
driver to access hardware registers owned by i915. It's also unrelated
to LPSS.
BR,
Jani.
