Subject: [PATCH] mfd: twl-core: convert to module_init()

There's no reason for twl-core to be subsys_inicall anymore. Anything
using twl that early needs a rethink, or deferred probe changes.

Boot tested and RTC wake tested (via TWL RTC) on OMAP platforms:
3530/Beagle, 3730/Beagle-xM, 3530/Overo, 3730/Overo-STORM, 4430/Panda,
4460/Panda-ES.

Hi Kevin,

It's done alreday here:
https://patchwork.kernel.org/patch/2477541/ - mfd: twl-core: convert to module_i2c_driver()
(Samuel has taken this one)
- and -
https://patchwork.kernel.org/patch/2477561/ - i2c: omap: convert to module_platform_driver()
(you can vote here - TWL can't be shifted without I2C)

(Sent from Web Outlook - sorry if format is wrong)
Best regards,
- Grygorii Strashko

Excellent, thanks for pointing it out, somehow I missed that thread. My
patch can be ignored.

This one (combined with the first one) makes twl_rtc fail to initialize
properly on OMAP3 DT boot, with an error like this:

twl_rtc rtc.22: hctosys: invalid date/time

Reverting that you get the expected result:

twl_rtc rtc.22: setting system clock to 2000-01-01 00:00:00 UTC (946684800)

I didn't debug any further, but for now, at least patch 2 needs a little
more work/debug.
