[PATCH 0/3] dt-bindings: display: renesas: du: Add vendor prefix to vsps property

[PATCH 0/3] dt-bindings: display: renesas: du: Add vendor prefix to vsps property

[Geert Uytterhoeven]

	Hi all,

When the Renesas-specific "vsps" property for the Renesas Display Unit
was introduced, it was forgotten to add a vendor prefix.

Hence this patch series fixes that in DT bindings, Linux driver, and DT
source files.  The driver retains backward compatibility with old DTBs
by falling back to the old property name when needed.

The first two patches are against Laurent's drm/du/next branch.
The last patch is against renesas-devel, and must be postponed until the
second patch has landed upstream.

Thanks!

[PATCH 1/3] dt-bindings: display: renesas: du: Add vendor prefix to vsps property

[Geert Uytterhoeven]

The Renesas-specific "vsps" property lacks a vendor prefix.
Add a "renesas," prefix to comply with DT best practises.

Move "renesas,vsps" below "renesas,cmms" to preserve alphabetical sort
order.
