nordic,nrf-uart

Vendor: Nordic Semiconductor

Description

These nodes are “uart” bus nodes.

Nordic nRF family UART.

This is the binding for the peripheral without EasyDMA support.
See the "nordic,nrf-uarte" binding for UARTE, i.e. UART with
EasyDMA.

Properties

Properties not inherited from the base binding file.

Name

Type

Details

disable-rx

boolean

Disable UART reception capabilities (only required to disable reception
if CONFIG_PINCTRL is enabled).

current-speed

int

Initial baud rate setting for UART. Only a fixed set of baud
rates are selectable on these devices.

Legal values: 1200, 2400, 4800, 9600, 14400, 19200, 28800, 31250, 38400, 56000, 57600, 76800, 115200, 230400, 250000, 460800, 921600, 1000000

clock-frequency

int

Clock frequency information for UART operation

hw-flow-control

boolean

Set to enable RTS/CTS flow control at boot time

parity

string

Configures the parity of the adapter. Enumeration id 0 for none, 1 for odd
and 2 for even parity. Default to none if not specified.

Legal values: 'none', 'odd', 'even'

pinctrl-0

phandles

Pin configuration/s for the first state. Content is specific to the
selected pin controller driver implementation.

pinctrl-1

phandles

Pin configuration/s for the second state. See pinctrl-0.

pinctrl-2

phandles

Pin configuration/s for the third state. See pinctrl-0.

pinctrl-3

phandles

Pin configuration/s for the fourth state. See pinctrl-0.

pinctrl-4

phandles

Pin configuration/s for the fifth state. See pinctrl-0.

pinctrl-names

string-array

Names for the provided states. The number of names needs to match the
number of states.
