Hello, This patch series adds a driver for the DSI encoder found in the R-Car V3U SoC, which is the first SoC in the family that supports DSI. The driver is based on an implementation from the BSP written by Luu Hoai, taken as-is in patch 02/15. The subsequent patches are cleanups. I'm posting this version as an RFC to allow Luu to review the cleanups, if desired. I've thus restricted the audience to the linux-renesas-soc mailing list. The next, non-RFC version will squash all driver patches into one and will be posted to dri-devel. There's one open question related to whether the DSI encoder clock needs to be controlled explicitly by the DU or not. Depending on the outcome of the tests, the driver could be further simplified.
