Jani Nikula aa17cdb4f8 drm/i915: initialize backlight max from VBT ... Normally we determine the backlight PWM modulation frequency (which we also use as backlight max value) from the backlight registers at module load time, expecting the registers have been initialized by the BIOS. If this is not the case, we fail. The VBT contains the backlight modulation frequency in Hz. Add platform specific functions to convert the frequency in Hz to backlight PWM modulation frequency, and use them to initialize the backlight when the registers are not initialized by the BIOS. v2: Fix SPT and VLV. Thanks to Clint for the VLV code.
