[PATCH V4 00/28] Enable Tegra PCIe root port features

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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, T124 based Jetson-TK1 platforms, Tegra20 and Tegra30
platforms.
