[PATCH 01/12] dt-bindings: panel: Add Samsung SOFEF00 DDIC with panel
From: David Heidelberg via B4 Relay
Date: Tue Nov 04 2025 - 17:18:01 EST
From: David Heidelberg <david@xxxxxxx>
Basic description for S6E3FC2X01 DDIC with attached panels
- Samsung AMS601NT22 6.01 inch, 1080x2160 pixels, 18:9 ratio
- Samsung AMS628NW01 6.28 inch, 1080x2280 pixels, 19:9 ratio
This panel has three supplies, while panel-simple-dsi is limited to one.
There is no user of this compatible, nor the compatible make sense.
Remove it from simple DSI panel definitions.
