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, with lots of further rework. If anyone is interested in the history, a broken down v1 is available from [1].
The driver has been successfully tested on the Falcon board, which connects an SN65DSI86 to the output of the DSI encoder. Further patches are needed for the ti-sn65dsi86 driver to enable usage in plain DP (non-eDP) mode, as the Falcon board has a mini-DP connector wired to the output of the SN65DSI86. This is work in progress (see [2]).
