400123bd01 dt-bindings: drm/bridge: ti-sn65dsi83: drop $ref to fix lvds-vod* warnings
The kernel test robot reported a warning related to the use of "$ref"
type definitions for custom endpoint properties
- "ti,lvds-vod-swing-clock-microvolt" and
- "ti,lvds-vod-swing-data-microvolt".

Using "$ref" with "uint32-array" is not correctly handled in this
context. Removing "$ref" and relying solely on "maxItems: 2" enforces
the intended requirement of specifying exactly two values, without
triggering a schema validation warning.

dt-bindings: display: bridge: sn65dsi83: Add interrupt
Both the TI SN65DSI83 and SN65DSI84 bridges have an IRQ pin to signal
errors using interrupt.

This interrupt is not documented in the binding.

Add the missing interrupts property.

63f4e7dfef dt-bindings: drm/bridge: ti-sn65dsi83: Add properties for ti,lvds-vod-swing
Add properties which can be used to specify LVDS differential output
voltage. Since this also depends on near-end signal termination also
include property which sets this. LVDS differential output voltage is
specified with an array (min, max), which should match the one from
connected device.

67006e30e2 dt-bindings: Drop more redundant 'maxItems/minItems'
Another round of removing redundant minItems/maxItems from new schema in
the recent merge window.

If a property has an 'items' list, then a 'minItems' or 'maxItems' with the
same size as the list is redundant and can be dropped. Note that is DT
schema specific behavior and not standard json-schema behavior. The tooling
will fixup the final schema adding any unspecified minItems/maxItems.

b4db237e1e dt-bindings: display: Fix graph 'unevaluatedProperties' related warnings
The graph schema doesn't allow custom properties on endpoint nodes for
'#/properties/port' and '#/$defs/port-base' should be used instead. This
doesn't matter until 'unevaluatedProperties' support is implemented.
