Hi all, This patch series adds devices nodes for the remaining Serial and High Speed Serial Communication Interfaces with FIFO ((H)SCIF) on the Renesas R-Car V4H (R8A779G0) SoC. Changes compared to v1[1]: - Replace S0D3_PER by SASYNCPERD1, as per R-Car V4H Hardware User's Manual rev. 0.54. SCIF[134] and HSCIF[13] can be accessed on expansion connectors on the White Hawk BreatOut Board using DT overlays available from [2]. They have been tested with a logic analyzer (to verify clocking) and with external loopback. I plan to queues this series in renesas-devel for v6.2. Thanks for your comments!
