Changes since v8:
- Fixed small compatible string typo caught by checkpatch
- Added custom select for 'fsl,imx6-mipi-dsi' (Rob)

- Dropped all nodes not adding any new constraints apart from
the recently upstreamed snps,dw-mipi-dsi.yaml (Rob)
Changes since v7:

- Removed the panel port documentation (Laurent)
- Wrapped lines at 80 chars, typo fixes, sort includes (Laurent)
Changes since v5:
- Fixed missing reg warning (Fabio)
- Updated dt-schema and fixed warnings (Rob)

+description: |
+ The i.MX6 DSI host controller is a Synopsys DesignWare MIPI DSI v1.01
+ IP block with a companion PHY IP.
+
+ These DT bindings follow the Synopsys DW MIPI DSI bindings defined in
+ Documentation/devicetree/bindings/display/bridge/dw_mipi_dsi.txt with
+ the following device-specific properties.
