Subject: [PATCH v2] arm64: dts: rockchip: add OPPs for rk3368-lion
Date:   Mon, 19 Feb 2018 08:26:26 +0100
Message-Id: <20180219072626.31874-1-klaus.goger@theobroma-systems.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This adds CPU operation points for the RK3368. We only add them to the
the RK3368-uQ7 SoM (Lion) because patches for the SoC where reverted
in the past.
commit 6354a06cbaa8 ("Revert "arm64: dts: rockchip: Add basic cpu
frequencies for RK3368"")
