Subject: [PATCH v4 1/2] dt-bindings: display: bridge: Add Chipone ICN6211 bindings
ICN6211 is MIPI-DSI to RGB Converter bridge from Chipone.
It has a flexible configuration of MIPI DSI signal input and
produces RGB565, RGB666, RGB888 output format.
Add dt-bingings for it.
Signed-off-by: Jagan Teki <jagan@...rulasolutions.com>

Changes for v4:
- fixed Laurent comments
- added regulators
- replace reset with EN
- fixed warnings pointed by Robert
Changes for v3:
- updated to new dt-bindings style
