Papadakos <papadakospan@gmail.com> as per the response from Rockchip regarding the maximum specification, we'll stay within the save area of frequencies - so not adding these higher ones. Overclocking a chip is a personal prerogative but should not be part of the general mainline devicetree. Heiko

This allows for greater max frequency on rk3328 boards, increasing performance. It has been included in Armbian (a linux distibution for ARM boards) for a while now without any reported issues https://github.com/armbian/build/blob/master/patch/kernel/rockchip64-default/enable-1392mhz-opp.patch https://github.com/armbian/build/blob/master/patch/kernel/rockchip64-default/enable-1512mhz-opp.patch Signed-off-by: Leonidas P.
