Hi,
here's v3 of am437x sk support. Patches tested on top of next-20140617.
Note that this series was tested with the following extra patches:

2.0.0.390.gcb682f8
Add support for TI's AM437x StarterKit Evaluation
Module.

changes since v1:
- add pinctrl for leds and matrix keypad
- added i2c1 and i2c0 speeds of 400k
- added voltage for vdds_ddr
- reordered mmc1 node
left the USB supply thing out because a) the driver doesn't use it and b) the
regulator will be automatically sitched off iff DRVVBUS signal goes low (that's
done automatically by the HW). Not to mention that there's really no benefit
from the kernel or userland point of view.
(I do have a patch for that locally though, so if people really want it, I can
easily fold the patch into this).

Strictly speaking, you are adding labels, not phandles. You can do
phandles without using labels, but the syntax is not so obvious. I'd
tell you what it is but offhand I don't remember. :)

I tested with omap2plus_defconfig + additionally enabling OMAPDSS and
Backlight in .config. Working great for me with ethernet, sdcard, lcd
panel and backlight all functional.
dmesg log attached - generated by kernel built from the repo/branch
Felipe pointed to in the cover letter for this series and obviously
running on an AM437x StarterKit EVM.

phandle-property = <&{/full/path/to/node@0xDEAD}>;
