nordic,nrf7000-qspi (on qspi bus)

Description

nRF7002 Wi-Fi chip with QSPI interface.

Properties

Properties not inherited from the base binding file.

Name

Type

Details

qspi-frequency

int

Maximum clock speed (in Hz) supported by the device.

This property is required.

qspi-quad-mode

boolean

If specified, Use QSPI in quad mode (4 IO lines) otherwise in
SPI mode (2 IO lines - MOSI & MISO).

qspi-rx-delay

int

Number of clock cycles from the rising edge of the SPI clock
until the input serial data is sampled.

Default value: 0

qspi-cpha

boolean

Set to indicate phase starts with asserted half-phase (CPHA=1).
The driver using this property must also use `cpol`.

qspi-cpol

boolean

Set to indicate that the clock leading edge is falling (CPOL=1).
The driver using this property requires also use `cpha`.

iovdd-ctrl-gpios

phandle-array

GPIO of the SoC controlling IO_VDD Control pin of the nRF70, either this
or iovdd-regulator needs to be set.

iovdd-regulator

phandle

Regulator controlling IO_VDD of the nRF70, either this or iovdd-ctrl-gpios
needs to be set.

bucken-gpios

phandle-array

GPIO of the SoC controlling BUCK_EN pin of the nRF70

This property is required.

host-irq-gpios

phandle-array

GPIO of the SoC controlling the HOST_IRQ pin of the nRF70

This property is required.

srrf-switch-gpios

phandle-array

GPIO of the RF Switch to control SR RF output to either SR Antenna
or shared Antenna with Wi-Fi

iovdd-power-up-delay-ms

int

Duration to wait after enabling IOVDD before attempting communications.
Default value of 1 comes from the nRF7002 DK/EK switch (TCK106AG): ~600us

Default value: 1

supply-power-up-delay-ms

int

Duration to wait after enabling the supply (supply-gpios and/or vin-supply)
before asserting BUCKEN.
Default value of 6 comes from the nRF7002 datasheet section 14.3.5 Supply
sequencing requirements which states Wait >= 6 ms

Default value: 6

supply-gpios

phandle-array

GPIO specifier that controls power to the device.

This property should be provided when the device has a dedicated
switch that controls power to the device.  The supply state is
entirely the responsibility of the device driver.

Contrast with vin-supply.

vin-supply

phandle

Reference to the regulator that controls power to the device.
The referenced devicetree node must have a regulator compatible.

This property should be provided when device power is supplied
by a shared regulator.  The supply state is dependent on the
request status of all devices fed by the regulator.

Contrast with supply-gpios.  If both properties are provided
then the regulator must be requested before the supply GPIOS is
set to an active state, and the supply GPIOS must be set to an
inactive state before releasing the regulator.

wifi-max-tx-pwr-2g-dsss

int

Maximum transmit power allowed in 2.4GHz band for DSSS/CCK rates

Default value: 18

wifi-max-tx-pwr-2g-mcs0

int

Maximum transmit power allowed in 2.4GHz band for MCS0

Default value: 14

wifi-max-tx-pwr-2g-mcs7

int

Maximum transmit power allowed in 2.4GHz band for MCS7

Default value: 14

wifi-max-tx-pwr-5g-low-mcs0

int

Maximum transmit power allowed in 5GHz band MCS0 low sub-band

Default value: 10

wifi-max-tx-pwr-5g-low-mcs7

int

Maximum transmit power allowed in 5GHz band MCS7 low sub-band

Default value: 10

wifi-max-tx-pwr-5g-mid-mcs0

int

Maximum transmit power allowed in 5GHz band MCS0 mid sub-band

Default value: 10

wifi-max-tx-pwr-5g-mid-mcs7

int

Maximum transmit power allowed in 5GHz band MCS7 mid sub-band

Default value: 10

wifi-max-tx-pwr-5g-high-mcs0

int

Maximum transmit power allowed in 5GHz band MCS0 high sub-band

Default value: 10

wifi-max-tx-pwr-5g-high-mcs7

int

Maximum transmit power allowed in 5GHz band MCS7 high sub-band

Default value: 10
