[RFC PATCH 00/15] R-Car V3U: DSI encoder driver

[Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>]

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.
