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.
