Vendor: STMicroelectronics

Description

These nodes are “uart” bus nodes.

STM32 UART

Properties

Properties not inherited from the base binding file.

Name

Type

Details

pinctrl-0

phandles

GPIO pin configuration for serial signals (RX, TX, RTS, CTS).  We expect
that the phandles will reference pinctrl nodes.

For example the USART1 would be
   pinctrl-0 = <&usart1_tx_pb6 &usart1_rx_pb7>;

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'
