renesas,smartbond-uart

Vendor: Renesas Electronics Corporation

Note

An implementation of a driver matching this compatible is available in drivers/serial/uart_smartbond.c.

Description

These nodes are “uart” bus nodes.

Renesas SmartBond(tm) UART

Properties

Node specific properties

Properties not inherited from the base binding file.

Name

Type

Details

periph-clock-config

int

 
Peripheral clock register configuration (COM domain)

This property is required.

current-speed

int

 
Initial baud rate setting for UART. Only a fixed set of baud
rates are selectable on these devices.

Legal values: 4800, 9600, 14400, 19200, 28800, 38400, 57600, 115200, 230400, 500000, 921600, 1000000, 2000000

hw-flow-control-supported

boolean

 
Set to indicate RTS/CTS flow control is supported.

rx-wake-gpios

phandle-array

 
GPIO configured as wake source

rx-wake-timeout

int

 
Time to prevent UART entering sleep mode after receiving data (ms)

dtr-gpios

phandle-array

 
DTR pin specification. DTR pin when active tells that the driver that there
is active client on the other side of serial line.
The device driver does not use DTR for hardware flow control.
When device is connected to computer serial converter usually asserts DTR
line when serial port is opened and ready for communication.
This line can be used in Smartbond(tm) driver to detect remote client presence.
If client is not present the device can disable UART, allowing for
power system management to enter more efficient power levels.

clock-frequency

int

 
Clock frequency information for UART operation

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'

stop-bits

string

 
Sets the number of stop bits.

Legal values: '0_5', '1', '1_5', '2'

data-bits

int

 
Sets the number of data bits.

Legal values: 5, 6, 7, 8, 9

pinctrl-0

phandles

 
Pin configuration/s for the first state. Content is specific to the
selected pin controller driver implementation.

pinctrl-1

phandles

 
Pin configuration/s for the second state. See pinctrl-0.

pinctrl-2

phandles

 
Pin configuration/s for the third state. See pinctrl-0.

pinctrl-3

phandles

 
Pin configuration/s for the fourth state. See pinctrl-0.

pinctrl-4

phandles

 
Pin configuration/s for the fifth state. See pinctrl-0.

pinctrl-names

string-array

 
Names for the provided states. The number of names needs to match the
number of states.

Deprecated node specific properties

Deprecated properties not inherited from the base binding file.

(None)

Base properties

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 “renesas,smartbond-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.

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

label

string

 
Human readable string describing the device (used as device_get_binding() argument)

See Important properties for more information.

This property is deprecated.

clocks

phandle-array

 
Clock gate information

clock-names

string-array

 
name of each clock

#address-cells

int

 
number of address cells in reg property

#size-cells

int

 
number of size cells in reg property

dmas

phandle-array

 
DMA channels specifiers

dma-names

string-array

 
Provided names of DMA channel specifiers

io-channels

phandle-array

 
IO channels specifiers

io-channel-names

string-array

string-array

 
Provided names of power domain specifiers

#power-domain-cells

int

 
Number of cells in power-domains property

zephyr,deferred-init

boolean

 
Do not initialize device automatically on boot. Device should be manually
initialized using device_init().

wakeup-source

boolean

 
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.

zephyr,pm-device-runtime-auto

boolean

 
Automatically configure the device for runtime power management after the
init function runs.

zephyr,disabling-power-states

phandles

 
List of power states that will disable this device power.
