Subject: [PATCH 1/3] ARM: dts: rockchip: add operating points and armclk references
Date: Sat, 13 Sep 2014 00:34:29 +0200 [thread overview]
Message-ID: <1410561271-19197-2-git-send-email-heiko@sntech.de> (raw)
In-Reply-To: <1410561271-19197-1-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.
