Cover letter [PATCH RFC 0/5] Dove PMU support
Quoted 11 lines · Andrew Lunn

Russell,

thanks for dropping those patches. I know you are packed with a bunch of other patch sets, so if you agree, I can pick up your Dove related patches and finish them.

One thing that comes into my mind is, that we moved Dove DT to mach-mvebu starting with v3.15-rc1 so we need to find a better place for the driver than mach-dove.

Create drivers/pmu ?

Hmm, I see no other folder it could sit in. Maybe, yes.

The cpufreq driver also needs access to registers within the pmu range. Should it be part of pmu.c, or should we export a regmap which cpufreq can use?

Not only cpufreq but also pinctrl as the first 16 mpps can have PMU related functions mapped to them. Syscon should do the trick.

Sebastian
