In my eyes we end up with two drivers in one file - but it can be done. A difference however is that in pm8941 the ps hold behavious (reboot vs power off) is controlled by this same block. So I have an additional patch that adds a restart handler here that sets the pmic in the right state before we pull pshold (but I haven't been able to test it properly). In pm8xxx this is handled in the pmic misc block and does not belong in this driver.

But you're right that it's a minor thing and can be done.
