As written, this driver is really not generic but very arm specific.
I don't think COMPILE_TEST is a good idea either, since arm_pm_restart
is only defined for the arm architecture. Did you try compiling allmodconfig
or allyesconfig for, say, x86_64 with this patch applied ?

I think this might benefit from using [1], which would make it really
generic.

This is great, I will base off this list. Did it make it to a branch anywhere?

Still in review. I hope it will make it into 3.17.
Of course it might be useful if you (and others)
help making the case for it.

Thanks,
