I think it goes like this:

Commit a99163e9e708 ("Merge drm/drm-next into drm-misc-next") was merged
into v5.12-rc1-dontuse and had "additionalProperties: false" and is the
common base for all later changes to this file.

Commit 6ff92deff711 ("dt-binding: display: bcm2711-hdmi: Add CEC and
hotplug interrupts") changes to "unevaluatedProperties: false" and is
merged into v5.12-rc1-dontuse.

Commit a3cb15cda1b8 ("dt-bindings: bcm2711-hdmi: Fix broken schema")
changes to "additionalProperties: false" and is merged into v5.12-rc2.

Commit e7cbc68a28e1 ("dt-binding: display: bcm2711-hdmi: Add
CEC and hotplug interrupts") changes (from a99163e9e708) to
"unevaluatedProperties: false" in the drm-misc and then drm trees.

When I come to merge the drm tree into linux-next, the merge base is
v5.12-rc3 and the only change to this file since v5.12-rc3 is in the
drm tree ...

Another way to look at it is that one one side of my merge, the line
goes from "additionalProperties: false" to "unevaluatedProperties:
false" and back to "additionalProperties: false" (so no net change)
and on the other side if my merge the line changes to
"unevaluatedProperties: false".
