Atmel SAM family USART

Properties

Properties not inherited from the base binding file.

Name

Type

Details

peripheral-id

int

peripheral ID

This property is required.

pinctrl-0

phandles

PIO 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 USART0 on SAME7x would be
   pinctrl-0 = <&pb0c_usart0_rxd0 &pb1c_usart0_txd0>;

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'
