[PATCH 1/2] media: dt-bindings: media: Introduce MEDIA_BUS_TYPE_DPI

[Fabio Estevam]

From: Fabio Estevam <festevam@denx.de>

Commit 18860529a599 ("media: dt-bindings: media: video-interfaces: Add
new bus-type") introduced a new bus-type for DPI video bus.

Introduce MEDIA_BUS_TYPE_DPI into video-interfaces.h to complete
the list of video interfaces.

[PATCH 2/2] media: dt-bindings: Use bus-types definitions from video-interfaces.h

[Fabio Estevam]

From: Fabio Estevam <festevam@denx.de>

To improve readability, replace hardcoding numerical constants with the
corresponding definitions from video-interfaces.h.

Based on commit c4cfd47eb4ac ("media: dt-bindings: Use new video interface
bus type macros in examples").

7 seems to have been a mistake, as this is a DSI endpoint, not a DPI
endpoint.

bus-type = <7> was added in commit 0a61ef9cc30d
("dt-bindings:drm/bridge:anx7625: add port@0 property").

Adding Xin Ji on CC for clarification.
