Subject[PATCH 3/3] arm64: dts: rockchip: shift boost frequency for rk3566-pinenote backlight
From: Maximilian Weigand <mweigand@mweigand.net>

The PineNote exhibits visible flickering of its backlight for certain
brightness settings. Alleviate this by enabling a frequency shift from
500 kHz to 560 kHz for the boost converter of the led driver.
