Subject: [PATCH v2 10/15] dt-bindings: panel: Add Bananapi S070WV20-CT16 ICN6211 MIPI-DSI to RGB bridge

Bananapi S070WV20-CT16 ICN6211 is 800x480, 4-lane MIPI-DSI to RGB bridge panel,
the same panel PCB comes with parallel RBG which is supported via
panel-simple driver with "bananapi,s070wv20-ct16" compatible.

But this binding is specific for MIPI DSI to RGB bridge panels,
which usually accessed using MIPI DSI controller driver.

for information:
- "bananapi,s070wv20-ct16" compatible for parallel RGB panels
- "bananapi,s070wv20-ct16-icn6211" compatible for MIPI-DSI to RGB
bridge panels

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

Changes for v2:
- Add detailed commit message
- Update the bindings as MIPI-DSI to RGB bridge

+Required properties:
+- compatible: must be "bananapi,s070wv20-ct16-icn6211"
+- reg: DSI virtual channel used by that screen
+- avdd-supply: analog regulator dc1 switch
+- dvdd-supply: 3v3 digital regulator
