As far as i know, the old Freescale BSP (2.6.35) contains a cpufreq driver
for mxs, which never goes to mainline. So i'm not sure what would be the
best way: porting the old driver or using cpufreq-cpu0.
First step would be to port the PMU driver into mainline.
I mean this regulator driver:
http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/drivers/regulator/mxs-regulator.c?h=imx_2.6.35_maintain
,so that you can do the voltage scaling.
thanks. Okay, that leads to more questions:
How can i test a ported mxs-regulator driver, that it's really working?
Is there any userspace interface?
Is there a good DT implementation of a similiar regulator driver, so i
can orientate on?
What are the recommend mailing lists for this porting (linux-pm and
linux-arm-kernel)?
