Subject: [PATCH 08/11] ARM: dts: rockchip: add operating points and armclk references
Date: Sat,  6 Sep 2014 01:06:11 +0200	[thread overview]
Message-ID: <1409958374-30937-9-git-send-email-heiko@sntech.de> (raw)
In-Reply-To: <1409958374-30937-1-git-send-email-heiko@sntech.de>

Add basic OPP entries for current supported Rockchip SoCs.
The operating points are currently very conservative, so individual
boards may opt to redefine them.
