[PATCH 0/3] drm/panel: ilitek-ili9881c: Read panel orientation

[John Keeping]

Support the "rotation" DT property for ILI9881C based panels.

The first patch is a fix for the binding, then the usual binding update
followed by the corresponding driver update.

John Keeping (3):
  dt-bindings: ili9881c: add missing panel-common inheritance
  dt-bindings: ili9881c: add rotation property
  drm/panel: ilitek-ili9881c: Read panel orientation

[PATCH 1/3] dt-bindings: ili9881c: add missing panel-common inheritance

[John Keeping]

The properties below refer to items in panel-common.yaml, which means
that needs to be referenced in the schema.

[PATCH 3/3] drm/panel: ilitek-ili9881c: Read panel orientation

[John Keeping]

The panel orientation needs to parsed from a device-tree and assigned to
the panel's connector in order to make orientation property available to
userspace. That's what this patch does for ILI9881C based panels.
