OMAP4 no longer boots in legacy mode so the code here is no longer used.

Could we modify the Makefile and build twl-common.o only for
CONFIG_ARCH_OMAP3?

We could get rid of all the #ifdef from the code that way. OMAP3 is the
only platform that still depends on this - Further, with this change,

(regulator: twl6030: add support for vdd1, vdd2 and vdd3 regulators)
will need a relook as well. currently part of the discussion with Mark
in [1]

Yep, I can do that. I'll send a separate patch to do this.

I don't see anything touching twl-common.c/h in the series.
But at the end we should get rid of the legacy support in all of the drivers
aimed for OMAP4+ gradually since it is pointless to keep dead code. Emphasis
on gradually ;)

right - now that we removed the set_voltage/get_voltage custom code,
there are no longer any way the code introduced in the commit can be
exercised.

Looks like the code above is also needed for omap3 based on the
if defined?

Yes it is still needed for OMAP3 when booting in legacy. I have moved these
two function down within the #if defined(CONFIG_ARCH_OMAP3) :

Oh OK sorry I missed that while glancing over it.

If we boot with DT (which is the case with OMAP4/5) this part was not even
executed, so the custom callbacks were not added from here for OMAP4. I might
be wrong here...

Now that I have looked at this: we might need to wait a bit and clean up other
files first: if we compile twl-common only if OMAP3 is selected, a build for
OMAP4/5 only will break due to missing symbol in pm.c (omap_pmic_late_init is
missing).
I could add another set of #ifdef there, but it defeats the point IMHO.
