Cover letter [RFC PATCH 0/2] drm/i915: get backlight max from vbt
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.
