This series of patches adds, - Tegra root port features like Gen2, AER, etc - Power and perf optimizations - Fixes like "power up sequence", "dev_err prints", etc This series of patches are tested on Tegra186 based Jetson-TX2, Tegra210 based Jetson-TX1 and T124 based Jetson-TK1 platforms. TODO: I don't have T20 and T30 platforms to verify this series. Thierry has kindly agreed to verify this series on T20 and T30. V2 takes care of comments from Bjorn and Thierry.
