Notes
- Some work on mainline has been done: https://www.rot13.org/~dpavlin/presentations/dc2019-mainline_kernel_tegra20.pdf although it seems the changes were made to the tegra20 ventana dts instead of creating a new dts for the indigo. Needs more work to include it in grade repo (and then mainline): https://github.com/dpavlin/linux/commit/b2b346ececf7d163bbc8df100e94e91f8216b08b
