Increase the frequency of the PWM signal that drives the LED backlight of the Pinebook Pro's panel, from about 1.35 KHz (which equals to the PWM period of 740,740 ns), to exactly 8 kHz (which equals to the PWM period of 125,000 ns). Using a higher PWM frequency for the panel backlight, which reduces the flicker, can only be beneficial to the end users' eyes.
On top of that, increasing the backlight PWM signal frequency reportedly eliminates the buzzing emitted from the Pinebook Pro's built-in speakers when certain backlight levels are set, which cause some weird interference with some of the components of the Pinebook Pro's audio chain.

Applied, thanks!
