Hello,

This series introduces upstream kernel support for Acer Iconia Tab A500
and ASUS Google Nexus 7 tablet devices. Please review and apply, thanks
in advance.

Changelog:

v3: - Improved device-tree node-names in accordance to review comments that
      were made by Thierry Reding to v2.

    - Corrected LVDS encoder powerdown-GPIO polarity on both A500 and Nexus 7
      because I implemented the DRM bridges support in the Tegra DRM driver
      and found that there was a mistake in the device-trees. The updated
      polarity also matches the boards schematics. Now DRM bridges support
      becomes mandatory since LVDS is getting disabled during of the encoder
      driver probing. I'll send the DRM patch separately from this series.

    - Replaced recently deprecated CONFIG_DRM_LVDS_ENCODER with the new
      CONFIG_DRM_LVDS_CODEC in tegra_defconfig.

    - Added more config options to tegra_defconfig, like pstore and thermal.

    - Added atmel,cfg_name to the A500 DT, which is a new upcoming property
      in 5.8+ that allows to specify the per-board hardware config file name.

v2: - Corrected "volume down" key-label in the grouper's device-tree and
      improved some other names in device-trees.

    - Added optional (upcoming in 5.8+) VDD/AVDD regulators to the touchscreen
      node in A500 device-tree.
