Subject[PATCH v3 2/3] dt-bindings: display: panel: Convert sitronix,st7701 to DT schema
Date
Convert the sitronix,st7701 panel bindings to DT schema.

Signed-off-by: Jagan Teki <jagan@amarulasolutions.com>

Changes for v3:
- update the licence, used (GPL-2.0-only OR BSD-2-Clause) since
I'm the author for old binding
- use panel-common.yaml
- mark true for common properties
- use maxItems: 1 for reg
- update example
Changes for v2:
- fix dt_binding_check
