[PATCH v5 2/3] dt-bindings: display: Fix brcm,bcm2835-hvs bindings for BCM2712
From: Dave Stevenson
Date: Fri Dec 20 2024 - 13:13:09 EST
Commit 6cfcbe548a3a ("dt-bindings: display: Add BCM2712 HVS bindings")
added the compatible string for BCM2712, but missed out that
the number of interrupts and clocks changed too.
The driver commit adding support for BCM2712 [1] also requires that
both interrupts and clocks are named, so the relevant -names
properties are also added to "required" for BCM2712.
Update to validate clock, interrupts, and their names for the BCM2712
variant. (There should be no change in the binding requirements for
the other variants).
[1] Commit 7687a12153d3 ("drm/vc4: hvs: Add support for BCM2712 HVS")
Fixes: 6cfcbe548a3a ("dt-bindings: display: Add BCM2712 HVS bindings")
