[PATCH 1/3] omap3: igep3: Add USB EHCI support for IGEP module.

[Enric Balletbo i Serra]

The OMAP3 IGEP module has one EHCI interface on board using
USB2HS port. GPIO183 is used as PHY reset.

[PATCH 2/3] omap3: igep3: Fix IGEP module second MMC channel power supply.

[Enric Balletbo i Serra]

The second MMC channel (used by the WLAN/BT module) is not linked to
power regulator. This causes the WLAN/BT module to fail being detected if
CONFIG_REGULATOR_DUMMY is not set.

This patch adds the two regulators that actually feed the WLAN/BT module
(1v8 from the TWL4030 VIO LDO, and a fixed 3v3). With that patch, the
second channel is properly detected.

Also change vmmc1 to use symbolic names instead of direct device
reference.

[PATCH 0/3] IGEP board changes for .38 merge window

[Tony Lindgren]

Hi,

I'll add these to the devel-board, let's see if we can get these and
the beagle patches still in.

In general, everybody, please send in new code for each merge window
by -rc6 so there's enough time for people to review and ack the code
and also have it be sitting in for-next before the merge window opens.

Regards,

Tony
