From: Jagan Teki
Date: Fri Apr 03 2020 - 10:25:11 EST


Convert the sitronix,st7701 panel bindings to DT schema.

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
