Papadakos Date: Fri, 1 Mar 2019 21:55:53 +0200 Subject: [PATCH v2] arm64: dts: rockchip: add more cpu operating points for RK3328 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.
