I think it's the right time for this code to be restructured. Adding 
more and more SoCs over this cruft is making this code worse and worse.

I believe this should be done as follows:

  - a generic struct describing particular PMU variant should be 
defined, with things like

	bool flush_cache_on_suspend;
	struct exynos_pmu_conf *pmu_conf;

or even function pointers, like

	void (*cpu_suspend)(unsigned long arg);

to handle things done currently using soc_is_*() macros, which we should 
get rid of.

- a DT match table would bind particular compatible strings with 
respective PMU variants structs,

- in general, this code should be made more like a normal driver, e.g. 
bind to a DT node and map registers dynamically.

Best regards,
Tomasz

 I recently came across RFC [1] posted by pankaj on similar lines, did
you get a chance to have look at this series.

Right. I noticed it once, but didn't get to review it yet, as I'm a bit 
busy with other things right now. Will try to take a look in next days.
