The series adds device tree support for OMAP hsmmc
driver.

Changes in V2:
-1- Minor fixes based on comments from Grant.
-2- Added a seperate compatible for omap3.
-3- Added a new binding "ti,needs-special-reset"
to handle some mmc modules which need special
softreset sequence.
-4- Updated board dts files with "status = disable;"
for unused mmc modules.

Rob,
I retained your ack on patch 1 despite the additional
binding that I added to handle the special softreset
sequence. Let me know if you have any issues with it.

Chris.
Patch 1 and Patch 2 apply cleanly on mmc-next and can
be taken in from the mmc tree after relevent acks from
DT folks.
Patch 3 and Patch 4 which update dts files, I plan to
push via linux-omap/Tony's tree.

The series is tested on omap4sdp (both external and emmc),
omap4panda amd omap3beagle boards.

Things to do:
-1- Card detect isn't functional and needs twl4030 gpio
to be DT converted.
-2- pbias cell programming is missing and needs an OMAP
control module driver.

Rajendra Nayak (4):
  mmc: omap_hsmmc: Convert hsmmc driver to use device tree
  mmc: omap_hsmmc: Avoid a regulator voltage change with dt
  arm/dts: OMAP4: Add mmc controller nodes and board data
  arm/dts: OMAP3: Add mmc controller nodes and board data
