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
