[PATCH 1/3] omap: rx51: Change the TWL4030 VMMC2 voltage constraints and supply name

[Jarkko Nikula]

I believe the VMMC2 constraints must be the same than with VAUX3. Older
boards are using TWL4030 VMMC2 supply for internal MMC whereas newer are
using VAUX3 that has more limited constraints defined in this same file.

More over, the VMMC2 supply is used also for analog audio domain and the
miminum analog voltage of the TLV320AIC34 codec is 2.7 V.

To combine these two facts, the patch changes supply name to V28_A as the
newer boards register VMMC2_30 for VAUX3 and uses the same constraints than
VAUX3 since those constraints are ok for the TLV320AIC34.

I was looking these from Maemo kernel sources, earlier patch [1] from
Eduardo and from commit f52eeee83d360d536cab1c0296eae0ec5f05e4dd.

I didn't find are the older boards using VMMC2 for audio but I assumed so.

[PATCH 2/3] omap: rx51: Add i2c2 board_info with tlv320aic3x

[Jarkko Nikula]

This makes possible to probe the audio codec and add another i2c2
components in the future.

Fix also indentation for the first omap_register_i2c_bus.

[PATCH 3/3] omap: rx51: Add supplies for the tlv320aic3x codec driver

[Jarkko Nikula]

Upcoming change to tlv320aic3x codec driver require four supplies.
Implement this by connecting analogic supplies to TWL4030 VMMC2 and digital
supplies to TWL4030 VIO.

Analogic supplies were able to find from Maemo kernel sources and earlier
patch from Eduardo:

http://marc.info/?l=linux-omap&m=125500331032616&w=2

I made an educated guess that digital codec supplies are connected to 1.8 V
IO voltage and it is derived from TWL4030 VIO (like in BeagleBoard).

Seems sensible to merge this along with the CODEC driver patch it
depends on if everyone else is happy (assuming no merge issues)?

Sounds good to me. I'll take the other ones, if there are merge issues
then we can move some of the other patches into your tree too.

OK, please resubmit to ASoC (Liam will be picking this one up since it's
OMAP-specific).

I would rather keep the board-rx51-peripherals.c in linux-omap sync
than get the N900 audio working as soon as possible :-)

None of these patches are build or boot critical so I can wait & repost
the last one when the codec patches hit into mainline.

Only harm from some missing board-rx51-peripherals.c patch is that
codec either doesn't probe or is kept in reset but system boots up
fine. And trees are clean too!
