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.

Add support for TI's AM437x StarterKit Evaluation Module. Cc: Josh Elliot <jelliott@ti.com> Cc: Darren Etheridge <detheridge@ti.com> Signed-off-by: Felipe Balbi <balbi@ti.com> --- 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).
