[PATCH 01/11] dt-bindings: display: panel: s6e3ha8: Adjust to reflect the DDIC and panel used

From: David Heidelberg via B4 Relay

Date: Sun Sep 20 2026 - 07:07:24 EST


From: David Heidelberg <david@xxxxxxx>

S6E3HA8 is the DDIC, while the panel used on the Samsung Galaxy S9 is
the Samsung AMB577PX01. Introduce a compatible reflecting that, adjust
the example, and deprecate the DDIC-only samsung,s6e3ha8 compatible.

Update the polarity to better match newly introduced compatibles with
fixed logic.
