Hi,
This is the third version of a series adding the CPU Frequency support
on Armada 37xx using DVFS. It is based on the initial work of Evan
Wang and Victor Gu.
As requested all the patches not directly related to the Armada 37xx
support had been sent in separate series.
The only other changes is replacing tab by space in the define as it
should have be already done in the v2.
The last patch is for arm-soc the arm-soc subsystem through mvebu and
update the device tree to support the CPU frequency scaling.
An update on the CPU clock driver is needed in order to take into
account the DVFS setting. It's the purpose of an other series already
sent, but is no dependencies between the series (for building or at
runtime).
Thanks,
Gregory
