Subject[PATCH v4 1/4] dt-bindings: Add cros-ec Type C port driver
Date
Some Chrome OS devices with Embedded Controllers (EC) can read and
modify Type C port state.

Add an entry in the DT Bindings documentation that lists out the logical
device and describes the relevant port information, to be used by the
corresponding driver.

Changes in v4:
- Rebased on top of usb-connector.yaml file, so the “connector” property
now directly references the “usb-connector” DT binding.

Changes in v3:
- Fixed license identifier.
- Renamed "port" to "connector".
- Made "connector" be a "usb-c-connector" compatible property.
- Updated port-number description to explain min and max values,
and removed $ref which was causing dt_binding_check errors.
- Fixed power-role, data-role and try-power-role details to make
dt_binding_check pass.
- Fixed example to include parent EC SPI DT Node.

Changes in v2:
- No changes. Patch first introduced in v2 of series.

+description:
+ Chrome OS devices have an Embedded Controller(EC) which has access to
+ Type C port state. This node is intended to allow the host to read and
+ control the Type C ports. The node for this device should be under a
+ cros-ec node like google,cros-ec-spi.
