This patch adds basic DT bindings for the PL11x CLCD cells
and make their fbdev driver use them.

Is this an old HW, and presumably there won't be new users for it?

AFAICT ARM really like to re-synthesize this piece of HW in every
new reference design they make. Plus a number of manufacturers
have used it in elder systems.

If
yes, this is probably fine. If not, you might want to look at the video
ports and endpoints, which is used by at least three not-yet-merged series:

[PATCHv3 00/41] OMAPDSS: DT support v3
[PATCH v5 00/11] imx-drm dt bindings
[RFC PATCH v2 00/21] Add DSI display support for Exynos based boards

Using bindings like that would be more future proof, even if the current
driver doesn't use them.

I take it that it shouldn't matter if the driver is for framebuffer or
DRM (as was implied by some answer here) the hardware
description should be the same no matter what, so the more
furture-proof the better.
