This patchset adds device-tree support to the Tegra MMC driver.
All device config is done via properties in the DT files instead
of hard-coded config options/function arguments.

I've tested this on my Seaboard and everything works fine,
including card detect. For the other T20 boards, I've used
the Linux kernel DTS files for the sdhci nodes where there
wasn't one already, or expanded the info that was already
there. Everything builds fine, but I haven't tested anything
but Seaboard.

v2: Changes as per Stephen's & Simon's review
v3: Changes as per Stephen/Lucas/Thierry/Simon's feedback
v4: Additional changes as per Stephen/Lucas/Thierry/Simon
v5: Additional changes as per Stephen/Lucas/Andy
v6: Additional changes requested by Stephen/Thierry
v7: Additional changes requested by Stephen

dts Makefile has the arch & board include paths added to DTS_CPPFLAGS.
This allows the use of '#include "xyz"' in the dts/dtsi file which
helps the C preprocessor find common dtsi include files.

v4: new
v5: add dts/dtsi paths to DTS_CPPFLAGS instead of DTC command line
v6: change all DT files to use #include instead of /include/
v7: change ARCH_CPU_DTS to "tegra20.dtsi" in T20 dts files

Linux dts files were used for those boards that didn't already
have sdhci info populated. Tamonten has their own dtsi file with
common sdhci nodes (sourced from Linux).

v2:
- cleanup comments in dts files/match w/kernel files
- add sdhci aliases in all dts files
- use tegra20-tamonten.dtsi from the kernel for AD boards
v3:
- include tamonten.dtsi file directly in AD dts files
- fix Seaboard power-gpios flags
- add cd-gpios for Colibri T20 Iris
- add include paths to DTC command
v4:
- move dts Makefile change to separate patch
v5:
- change /include/ to #include, allows C preprocessor to find files
v6:
- change ARCH_CPU_DTS to "tegra20.dtsi"
- change cd-gpios flags to 1, active-low
v7:
- negate change from ARCH_CPU_DTS to "tegra20.dtsi", since it has
-  already been done in the preceding patch

  To: u-boot

tegra_mmc_init() now parses the DT info for bus width, WP/CD GPIOs, etc.
Tested on Seaboard, fully functional.

Tamonten boards (medcom-wide, plutux, and tec) use a different/new
dtsi file w/common settings.

Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>
---
v2:
- all boards now call tegra_mmc_init once, w/no params
- count MMC controllers, not aliases
- AD boards (medcom/plutux/tec) use common tegra20-tamonten.dtsi
v3:
- move any power init inside board's pin_mux_mmc function, and/or
 create pin_mux_mmc function if necessary.
- move board_mmc_init out of each board file and into ../common/board.c
v4:
- remove #ifdef CONFIG_TEGRA_MMC from trimslice.c
- fix minor whitespace issue in board/nvidia/common/board.c
- remove marking of used node_list entries in MMC driver, not needed
v5:
- restore previous debug statements, remove any new ones
- fix pwr_gpio/cd_gpio initialization in do_mmc_init
- update copyright to 2013
v6:
- change tegra_mmc_getcd to reflect new cd-gpios polarity (active-low)
v7:
- no change

Just to be explicit, this latest series/version,

You've explicitly mentioned the changes in the individual patches, so
I'd be inclined to just leave out the list here. If you keep it, it'd be
useful to cut/paste all the changes from the individual patches, or
summarize them explicitly; simply listing who requested the changes
isn't that useful.
