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.

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.

pinctrl-0

phandles

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

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'
