Subject: [PATCH 3/3] ARM: rockchip: add a cpufreq-cpu0 device
Date: Sat, 13 Sep 2014 00:34:31 +0200 [thread overview]
Message-ID: <1410561271-19197-4-git-send-email-heiko@sntech.de> (raw)
In-Reply-To: <1410561271-19197-1-git-send-email-heiko@sntech.de>
Rockchip SoCs can sucessfully use the generic cpufreq-cpu0 driver to
do frequency scaling. Therefore add a platform device in the machine
init code.
