Subject: [PATCH v6 1/5] dt-bindings: usb: Add binding for Realtek RTS5411 hub controller
Date: Fri,  5 Mar 2021 11:38:49 -0800
Message-ID: <20210305113832.v6.1.I248292623d3d0f6a4f0c5bc58478ca3c0062b49a@changeid> (raw)
In-Reply-To: <20210305193853.2040456-1-mka@chromium.org>

The Realtek RTS5411 is a USB 3.0 hub controller with 4 ports.

This initial version of the binding only describes USB related
aspects of the RTS5411, it does not cover the option of
connecting the controller as an i2c slave.

Changes in v6:
- Realtek binding instead of generic onboard_usb_hub
- added 'companion-hub' property
- added reference to 'usb-device.yaml'
- 'fixed' indentation of compatible entries to keep yamllint happy
- added 'additionalProperties' entry
- updated commit message

Changes in v5:
- updated 'title'
- only use standard USB compatible strings
- deleted 'usb_hub' node
- renamed 'usb_controller' node to 'usb-controller'
- removed labels from USB nodes
- added 'vdd-supply' to USB nodes

Changes in v4:
- none

Changes in v3:
- updated commit message
- removed recursive reference to $self
- adjusted 'compatible' definition to support multiple entries
- changed USB controller phandle to be a node

Changes in v2:
- removed 'wakeup-source' and 'power-off-in-suspend' properties
- consistently use spaces for indentation in example
