Re: [PATCH v2 1/2] dt-bindings: display: panel: Document Raydium RM69220 DDIC

[sashiko-bot@kernel.org]

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] The newly added DT binding schema introduces a dtbs_check regression for an existing dummy panel node in `arch/arm64/boot/dts/qcom/milos-nothing-asteroids.dts`. The existing device tree uses `compatible = "boe,bf068mwm-td0"` for a simple-framebuffer dummy node, but lacks the strictly required properties mandated by the new schema.

dt-bindings: display: panel: Document Raydium RM69220 DDIC

Document the Raydium RM69220 DDIC and the BOE BF068MWM-TD0 6.77"
1080x2392 AMOLED display panel used in the Nothing Phone (3a).

[Severity: Low]
Will this strict compatible requirement trigger dtbs_check failures for the
existing dummy panel node in
arch/arm64/boot/dts/qcom/milos-nothing-asteroids.dts?

That file currently uses this compatible string for a dummy node:

			/* Dummy panel for simple-framebuffer dimension info */
			panel: dummy-panel {
				compatible = "boe,bf068mwm-td0";
				height-mm = <157>;
				width-mm = <71>;
			};

Since the new schema mandates a two-item array with "raydium,rm69220" and
several other required properties like dvdd-supply, reg, and port, validating
the existing dts against this schema appears to cause validation failures.

Should the dummy node's compatible string be updated to avoid conflicting with
the actual hardware schema, or should the dts update be included in this
series?
