From 6f2dea1f5fdb73eb2e050d9ebe990121d557e519 Mon Sep 17 00:00:00 2001 From: Romain Perier Date: Fri, 18 Aug 2017 14:17:01 +0200 Subject: [PATCH] arm64: dts: rockchip: Add basic cpu frequencies for RK3368 This adds and enable the operating points that have been tested and are currently supported by the SoC. This also adds clocks for ARMCLKL and ARMCLKB.
