[PATCH v7 9/9] drm/i915: Set PWM divider to match desired frequency in vbt

2017-05-11 Thread Puthikorn Voravootivat
Read desired PWM frequency from panel vbt and calculate the value for divider in DPCD address 0x724 and 0x728 to have as many bits as possible for PWM duty cyle for granularity of brightness adjustment while the frequency is still within 25% of the desired frequency. Signed-off-by: Puthikorn Vorav
