This series adds Tegra210, Tegra186, and Tehra194 QSPI driver and enables QSPI on Jetson Nano and Jetson Xavier NX. QSPI controller is available on Tegra210, Tegra186 and Tegra194. Tegra186 and Tegra194 has additional feature of combined sequence mode where command, address and data can all be transferred in a single transfer. Combined sequence mode is useful with DMA mode transfer. This series does not have combined sequence mode feature as Tegra186/Tegra194 GPCDMA driver is not upstreamed yet. This series includes - dt-binding document - QSPI driver for Tegra210/Tegra186/Tegra194 - Enables QSPI on Jetson Nano and Jetson Xavier NX.
