Subject: [PATCH V4 00/28] Enable Tegra PCIe root port features
Date: Thu, 16 May 2019 11:22:39 +0530
Message-ID: <20190516055307.25737-1-mmaddireddy@nvidia.com> (raw)

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.
