[PATCH 0/3] ARM: tegra: defconfig updates for 3.8

[Thierry Reding]

The following set of patches enables the Tegra DRM driver along with the
framebuffer console and the PWM backlight driver to light up panels that
are driven by the DRM driver. A third patch enables SquashFS, which is
used as the root filesystem on Tamonten-based boards.

[PATCH 2/3] ARM: tegra: Update default configuration (DRM)

[Thierry Reding]

Enable the NVIDIA Tegra DRM driver along with CMA to support large
contiguous buffer allocations. While at it, also enable the framebuffer
console that can be used on top of tegra-drm.

Thanks, I have squashed the series into Tegra's for-3.8/defconfig
branch. Squashed rather than applied since there's still a desire to
keep the number of defconfig-related commits minimal.
