nuvoton,npcx-uart

Description

These nodes are “uart” bus nodes.

Nuvoton, NPCX-UART node

Properties

Properties not inherited from the base binding file.

Name	Type	Details
`pinctrl-0`	`phandles`	configurations of pinmux controllers This property is required.
`uart-rx`	`phandle`	Mapping table between Wake-Up Input (WUI) and uart rx START signal. For example the WUI mapping on NPCX7 UART1 would be uart-rx = <&wui_cr_sin1>; This property is required.
`clock-frequency`	`int`	Clock frequency information for UART operation
`current-speed`	`int`	Initial baud rate setting for UART
`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'`

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 “nuvoton,npcx-uart” compatible.

Name	Type	Details
`reg`	`array`	register space This property is required. See Important properties for more information.
`clocks`	`phandle-array`	Clock gate information This property is required.
`label`	`string`	Human readable string describing the device (used as device_get_binding() argument) 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`	`array`	interrupts for device See Important properties for more information.
`interrupts-extended`	`compound`	extended interrupt specifier for device
`interrupt-names`	`string-array`	name of each interrupt
`interrupt-parent`	`phandle`	phandle to interrupt controller node
`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.
