The ASUS Transformer T30 family are 2-in-1 detachable tablets and AiO developed by ASUS that run the Android operating system (TF600T runs Windows RT and P1801-T runs Android and Windows). The T30 Transformers feature a 10.1-inch display (apart P1801-T), an Nvidia Tegra 3 quad-core chip, 1/2 GB of RAM, and 16/32 GB of storage. Transformers board derives from Nvidia Cardhu development board. This patch brings support for 7 known Transformer devices: - ASUS Transformer Prime TF201 - ASUS Transformer Pad TF300T/TF300TG/TF300TL - ASUS VivoTab RT TF600T (Windows RT based) - ASUS Transformer Infinity TF700T - ASUS Portable AiO P1801-T Tested-by: Andreas Westman Dorcsak <hedmoo@yahoo.com> # all devices Signed-off-by: Svyatoslav Ryhel <clamor95@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
