[Intel-gfx] [RFC PATCH 0/2] drm/i915: get backlight max from vbt

[Jani Nikula]

Found this while cleaning up some old branches I have in my repo...

I'm posting this more as archival for posterity than as a serious
attempt to get this merged. There was a bunch of archeology involved in
figuring out the Hz to PWM modulation frequency conversion, so someone
might find that useful.

Particularly the vlv setup could use some cleanup and only falling back
to the hardcoded value if vbt is not set. And the hardcoded default
could now be expressed in Hz instead of raw pwm value. But meh until
someone really needs this.


BR,
Jani.
