Subject: [PATCH v15 08/10] dt-bindings: display: bridge: it6505: Add mode-switch support
Date: Fri, 31 Mar 2023 17:11:43 +0800 [thread overview]
Message-ID: <20230331091145.737305-9-treapking@chromium.org> (raw)
In-Reply-To: <20230331091145.737305-1-treapking@chromium.org>
ITE IT6505 can be used in systems to switch the DP traffic between
two downstreams, which can be USB Type-C DisplayPort alternate mode
lane or regular DisplayPort output ports.
Update the binding to accommodate this usage by introducing a
data-lanes and a mode-switch property on endpoints.
Signed-off-by: Pin-yen Lin <treapking@chromium.org>
---
(no changes since v12)
Changes in v12:
- Fixed the schema of "data-lanes" property for it6505
- Reworded the description of the mode-switch property
Changes in v11:
- Updated the description of the endpoints in the bindings
- Referenced video-interfaces.yaml instead for the endpoints binding
- Removed duplicated definitions from inherited schema
Changes in v9:
- Fixed subject prefix again
- Changed the naming of the example node for it6505
Changes in v8:
- Updated bindings for data-lanes property
- Fixed subject prefix
Changes in v7:
- Fixed issues reported by dt_binding_check.
- Updated the schema and the example dts for data-lanes.
- Changed to generic naming for the example dts node.
Changes in v6:
- Remove switches node and use endpoints and data-lanes property to
describe the connections.
