Subject: [PATCH 0/4] Dove cpufreq driver
Date: Sat, 19 Oct 2013 14:37:37 +0200 [thread overview]
Message-ID: <1382186261-14482-1-git-send-email-andrew@lunn.ch> (raw)
Marvell Dove can run its CPU at two different frequencies. Add a
cpufreq driver.
These patches are based on top of Rafael's for-next branch, since
there have been a lot of changes to the cpufreq core code.
However, this driver also has a run time dependency on the PMU
interrupt controller patches:
http://www.spinics.net/lists/devicetree/msg06547.html
If the PMU interrupt controller is not available, the cpufreq probe
function will fail, but the machine keeps running O.K.
Probably Jason will want to take the mvebu patches, and Rafeal or
Viresh for the cpufreq driver itself.
Once github comes back online, the following branch will have these patches
and the dependencies.
