ARM: tegra: add Acer Chromebook 13 device tree
The Acer Chromebook 13, codenamed Big, contains an NVIDIA tegra124 processor and is similar to the Venice2 reference platform. The keyboard, USB 2, audio, sdcard and emmc have been tested and work on the 1366x768 models. The Full HD models haven't been tested yet. WiFi does not yet work, it needs at least some PMIC changes to enable the 32k clock. The elan trackpad is not yet functional but hopefully will be soon as there are patches under review. There is also an issue on reboot because the TPM isn't reset. It will cause the stock firmware to enter recovery mode. This can be worked around by an EC-reset, press the refresh and power keys at the same time. Signed-off-by: Dylan Reid <dgreid@chromium.org> Signed-off-by: Stephen Warren <swarren@nvidia.com>
