Thanks Viresh, I'm out of the office right now but will look at this more
closely early next year.
There's discussions starting among various folks about how to handle
big.LITTLE and what role cpufreq governors vs. platform code play a part in
that, so all this will probably be something a little
Latest big LITTLE systems for ARM SoC's have following kind of ranges of freqs:
LITTLE CPU ranges: x MHz -> y MHz
big CPU ranges: y + delta -> z MHz
For these, we use hispeed_freq as y MHz, to avoid a switch of clusters from
LITTLE to big when load burst comes. Similar to non big.LITTLE systems, w
