Subject: [PATCH] ARM: dts: rockchip: update rk3288-veyron cpu operating points
Date: Thu, 31 Mar 2016 23:24:43 +0200 [thread overview]
Message-ID: <1459459483-5356-1-git-send-email-heiko@sntech.de> (raw)
The generic operating points specified in rk3288.dtsi are specified by
Rockchip as conservative and for all cases.
In contrast the Veyron ChromeOS devices are supposed to use a special
chip variant often called rk3288-c and use different operating points
in their kernel also including a higher max frequency.
So override the operating points for veyron devices.
