Tested-by: Linus Walleij <linus.walleij@xxxxxxxxxx> (Mostly for the DTS refactoring, which is what affects APQ8060) I guess the APQ8064 cpufreq and APQ8060 isn't actually far apart, so it should be possible to fix APQ8060 as well, but we can take that another day. I always wanted to fix the SAW2 regulators. Yours, Linus Walleij
