[PATCH 0/3] ARM: tegra: Enable HDMI on Tamonten carriers

[Thierry Reding]

The three patches in this series enable the HDMI output on Plutux and
TEC. The Medcom-Wide only has an LVDS output and the TEC has an LVDS
output as well, but since they depend on the videomode helpers and the
power-sequences patch series, they will only be enabled in subsequent
patches.

[PATCH 1/3] ARM: tegra: tamonten: Add host1x support

[Thierry Reding]

Hook up the required regulators, I2C DDC adapter and hotplug detect GPIO
to the Tamonten HDMI output. Carrier boards still need to explicitly
enable the output to use it.

Thanks, I've applied the series to Tegra's for-3.8/dt branch.
