Nordic nRF family UARTE (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.
`memory-regions`	`phandle-array`	List of memory region phandles
`memory-region-names`	`string-array`	A list of names, one for each corresponding phandle in memory-region

Deprecated properties not inherited from the base binding file.

Name	Type	Details
`tx-pin`	`int`	IMPORTANT: This option will only be used if the new pin control driver is not enabled. The TX pin to use. For pins P0.0 through P0.31, use the pin number. For example, to use P0.16 for TX, set: tx-pin = <16>; For pins P1.0 through P1.31, add 32 to the pin number. For example, to use P1.2 for TX, set: tx-pin = <34>; /* 32 + 2 */
`rx-pin`	`int`	IMPORTANT: This option will only be used if the new pin control driver is not enabled. The RX pin to use. The pin numbering scheme is the same as the tx-pin property's.
`rts-pin`	`int`	IMPORTANT: This option will only be used if the new pin control driver is not enabled. The RTS pin to use. The pin numbering scheme is the same as the tx-pin property's.
`cts-pin`	`int`	IMPORTANT: This option will only be used if the new pin control driver is not enabled. The CTS pin to use. The pin numbering scheme is the same as the tx-pin property's.
`rx-pull-up`	`boolean`	IMPORTANT: This option will only be used if the new pin control driver is not enabled. Enable pull-up resistor on the RX pin.
`cts-pull-up`	`boolean`	IMPORTANT: This option will only be used if the new pin control driver is not enabled. Enable pull-up resistor on the CTS pin.

Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “nordic,nrf-uarte” compatible.

Name	Type	Details
`reg`	`array`	register space This property is required. See Important properties for more information.
`interrupts`	`array`	interrupts for device This property is required. See Important properties for more information.
`status`	`string`	indicates the operational status of a device Legal values: `'ok'`, `'okay'`, `'disabled'`, `'reserved'`, `'fail'`, `'fail-sss'` See Important properties for more information.
`compatible`	`string-array`	compatible strings This property is required. See Important properties for more information.
`reg-names`	`string-array`	name of each register space
`interrupts-extended`	`compound`	extended interrupt specifier for device
`interrupt-names`	`string-array`	name of each interrupt
`interrupt-parent`	`phandle`	phandle to interrupt controller node
`label`	`string`	Human readable string describing the device (used as device_get_binding() argument) See Important properties for more information. This property is deprecated.
`clocks`	`phandle-array`	Clock gate information
`clock-names`	`string-array`	name of each clock
`#address-cells`	`int`	number of address cells in reg property
`#size-cells`	`int`	number of size cells in reg property
`dmas`	`phandle-array`	DMA channels specifiers
`dma-names`	`string-array`	Provided names of DMA channel specifiers
`io-channels`	`phandle-array`	IO channels specifiers
`io-channel-names`	`string-array`	Provided names of IO channel specifiers
`mboxes`	`phandle-array`	mailbox / IPM channels specifiers
`mbox-names`	`string-array`	Provided names of mailbox / IPM channel specifiers
`wakeup-source`	`boolean`	Property to identify that a device can be used as wake up source. When this property is provided a specific flag is set into the device that tells the system that the device is capable of wake up the system. Wake up capable devices are disabled (interruptions will not wake up the system) by default but they can be enabled at runtime if necessary.
`power-domain`	`phandle`	Power domain the device belongs to. The device will be notified when the power domain it belongs to is either suspended or resumed.
