Subject: [PATCH v2 01/12] dt-bindings: panel: Convert Samsung SOFEF00 DDIC
into standalone yaml
From: David Heidelberg <david@...t.cz>
Reason for moving from simple panel is this DDIC has three supplies,
while panel-simple-dsi is limited to one.
Previous compatible only described the DDIC, but didn't include panel
connected to it. Let's fix it, and offer bindings authors two
compatibles to distinguish the connected panel.
Basic description for SOFEF00 DDIC with attached panels
- Samsung AMS601NT22 6.01 inch, 1080x2160 pixels, 18:9 ratio
- Samsung AMS628NW01 6.28 inch, 1080x2280 pixels, 19:9 ratio
There is only one user which uses samsung,sofef00 and it's updated to
comply within this patch series.
