Your patch-set is based on v3.13-rc1 but I sent a patch-set [0] to fix
a few regressions for IGEPv2 when we moved to DT-only boot. One of
these patches added the needed DSS pinmuxing and these were included
in v3.13-rc2.
So to test your branch I cherry-picked:
d526daeb ("ARM: dts: omap3-igep0020: Add pinmux setup for i2c devices")
50592dc3 ("ARM: dts: omap3-igep0020: Add pinmuxing for DVI output")
Also, for 3.13 I added a DT hack to make dpi_init_regulator() succeed
and find the VDDS_DSI regulator. That patch is mainline comit
2f2befd82 ("ARM: dts: omap3-igep0020: name twl4030 VPLL2 regulator as vdds_dsi")
Now that I think about it, you may want to add a revert for that patch
on your series too since this hack is not needed anymore with your DSS
bindings.
