Hi Peter,

I'm trying to get frequency scaling working in linux-3.0, and it after
digging into why cpufreq-info works in 2.6.32 and doesn't in 3.0, I've
found that omap_cpu_init() returs -ENOENT due to clk_get(NULL,
virt_prcm_set) failing.
In the older 2.6.32 kernel it used arm_fck for MPU_CLK instead of
virt_prcm_set, but that option isn't in the linux-3.0 source (or the
current source in tony's tree on github.com). I tried reverting to
arm_fck, but on a DM3730 cpupfreq-info only shows 600Mhz as a
possibility, and none of the other operating points.
Does anyone have CPU frequency scaling working in linux-3.0 and have
any suggestions on what I'm doing wrong?
I recently posted[1] an updated CPUfreq driver that is proposed for merge
in v3.2.
It's also availble in the 'for_3.2/omap-cpufreq' branch of my github
repo: git://github.com/khilman/linux-omap-pm.git
