Hi Simon, Magnus, R-Car Gen3 Hardware User Manual Rev. 1.50 (finally) documents DMA support for the SCIF2 serial port on R-Car H3, M3-W, M3-N, E3, and D3 (albeit with the wrong MID/RID, due to a hex-vs-dec mix-up).
This patch series enables DMA for the SCIF2 serial ports on R-Car Gen3 and RZ/G2 SoCs that do not have DMA enabled yet. It consists of 5 separate patches, one for each SoC, to ease backporting. Changes compared to v1: - Add Fixes tags where appropriate. This has been tested on R-Car M3-W, M3-N, and E3. Thanks!
