atmel,sam0-uart¶
Vendor: Atmel Corporation
Description¶
These nodes are “uart” bus nodes.
Atmel SAM0 SERCOM UART driver
Properties¶
Properties not inherited from the base binding file.

---|---|---|
|
|
Receive Data Pinout
This property is required. |
|
|
Transmit Data Pinout
This property is required. |
|
|
Enable collision detection for half-duplex mode.
|
|
|
PORT pin configuration for RXD & TRD signals. We expect that
the phandles will reference pinctrl nodes. These nodes will
have a nodelabel that matches the Atmel SoC HAL defines and
be of the form p<port><pin><periph>_<inst>_<signal>.
For example the SERCOM0 on SAMR21 would be
pinctrl-0 = <&pa5d_sercom0_pad1 &pa4d_sercom0_pad0>;
This property is required. |
|
|
Clock frequency information for UART operation
|
|
|
Initial baud rate setting for UART
|
|
|
Set to enable RTS/CTS flow control at boot time
|
|
|
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: |
Deprecated properties not inherited from the base binding file.
(None)
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.

register space
This property is required. See Important properties for more information. |
|
|
interrupts for device
This property is required. See Important properties for more information. |
|
|
Clock gate information
This property is required. |
|
|
name of each clock
This property is required. |
|
|
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>;
|
|
|
Required if the dmas property exists. This should be "tx" and "rx"
to match the dmas property.
For example
dma-names = "tx", "rx";
|
|
|
Human readable string describing the device (used as device_get_binding() argument)
This property is required. See Important properties for more information. |
|

|
|
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.
