[PATCH v2 0/2] drm: rcar-du: Fix more invalid register writes

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

Hello,

Following the "[PATCH 0/2] drm: rcar-du: Avoid writing reserved register
fields" series ([1]), this series addresses more invalid register
writes in the R-Car DU driver. Patch 1/2 first renames some register
field macros to increase readability, and patch 2/2 fixes the invalid
writes.

The rationale is the same as for the previous series: the current
implementation is likely fine, but doesn't pass the functional safety
requirements as it doesn't match the documentation.

The series supersedes the patch "[PATCH] drm: rcar-du: Write correct
values in DORCR reserved fields" ([2]) that I have just sent, which was
messing the 1/2 dependency. Patch 2/2 is otherwise identical to [2].
