atmel,sam0-uart¶

Description¶

These nodes are “uart” bus nodes.

Atmel SAM0 SERCOM UART driver

Properties¶

Properties not inherited from the base binding file.

Name	Type	Details
`rxpo`	`int`	Receive Data Pinout This property is required.
`txpo`	`int`	Transmit Data Pinout This property is required.
`collision-detection`	`boolean`	Enable collision detection for half-duplex mode.
`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 “atmel,sam0-uart” 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.
`clocks`	`phandle-array`	Clock gate information This property is required.
`clock-names`	`string-array`	name of each clock This property is required.
`dmas`	`phandle-array`	Optional TX & RX dma specifiers. Each specifier will have a phandle reference to the dmac controller, the channel number, and peripheral trigger source. For example dmas for TX, RX on SERCOM3 dmas = <&dmac 0 0xb>, <&dmac 0 0xa>;
`dma-names`	`string-array`	Required if the dmas property exists. This should be "tx" and "rx" to match the dmas property. For example dma-names = "tx", "rx";
`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-extended`	`compound`	extended interrupt specifier for device
`interrupt-names`	`string-array`	name of each interrupt
`interrupt-parent`	`phandle`	phandle to interrupt controller node
`#address-cells`	`int`	number of address cells in reg property
`#size-cells`	`int`	number of size cells in reg property
`io-channels`	`phandle-array`	IO channels specifiers
`io-channel-names`	`string-array`	Provided names of IO channel specifiers
