13description:
14 Devices connected over serial/UART, expressed as children of a serial
15 controller, might need similar properties, e.g. for configuring the baud
16 rate.

18properties:
19 max-speed:
20 $ref: /schemas/types.yaml#/definitions/uint32
21 description:
22 The maximum baud rate the device operates at.
23 This should only be present if the maximum is less than the slave
24 device can support. For example, a particular board has some
25 signal quality issue or the host processor can't support higher
26 baud rates.
27
28 current-speed:
29 $ref: /schemas/types.yaml#/definitions/uint32
30 description: |
31 The current baud rate the device operates at.
32 This should only be present in case a driver has no chance to know
33 the baud rate of the slave device.
34 Examples:
35 * device supports auto-baud
36 * the rate is setup by a bootloader and there is no way to reset
37 the device
38 * device baud rate is configured by its firmware but there is no
39 way to request the actual settings
