- description:
- Devices connected over serial/UART, expressed as children of a serial
- controller, might need similar properties, e.g. for configuring the baud
- rate.
- properties:
- max-speed:
- $ref: /schemas/types.yaml#/definitions/uint32
- description:
- The maximum baud rate the device operates at.
- This should only be present if the maximum is less than the slave
- device can support. For example, a particular board has some
- signal quality issue or the host processor can't support higher
- baud rates.
- current-speed:
- $ref: /schemas/types.yaml#/definitions/uint32
- description: |
- The current baud rate the device operates at.
- This should only be present in case a driver has no chance to know
- the baud rate of the slave device.
- Examples:
- * device supports auto-baud
- * the rate is setup by a bootloader and there is no way to reset
- the device
- * device baud rate is configured by its firmware but there is no
- way to request the actual settings
- additionalProperties: true
