Qualcomm Technologies IEEE 802.11be PCIe devices with WSI interface.
The ath12k devices (QCN9274) feature WSI support. WSI stands for
WLAN Serial Interface. It is used for the exchange of specific
control information across radios based on the doorbell mechanism.
This WSI connection is essential to exchange control information
among these devices.
The WSI interface includes TX and RX ports, which are used to connect
multiple WSI-supported devices together, forming a WSI group.
Diagram to represent one WSI connection (one WSI group) among
three devices.

Support for the Wifi chip WFxxx from Silicon Labs. Currently, the only device
from the WFxxx series is the WF200 described here:
https://www.silabs.com/documents/public/data-sheets/wf200-datasheet.pdf
The WF200 can be connected via SPI or via SDIO.
For SDIO:
Declaring the WFxxx chip in device tree is mandatory (usually, the VID/PID is
sufficient for the SDIO devices).
It is recommended to declare a mmc-pwrseq on SDIO host above WFx. Without
it, you may encounter issues during reboot. The mmc-pwrseq should be
compatible with mmc-pwrseq-simple. Please consult
Documentation/devicetree/bindings/mmc/mmc-pwrseq-simple.yaml for more
information.

* Texas Instruments wl1251 wireless lan controller
The wl1251 chip can be connected via SPI or via SDIO. This
document describes the binding for the SPI connected chip.
Required properties:
- compatible : Should be "ti,wl1251"
- reg : Chip select address of device
- spi-max-frequency : Maximum SPI clocking speed of device in Hz
- interrupts : Should contain interrupt line
- vio-supply : phandle to regulator providing VIO
Optional properties:
- ti,wl1251-has-eeprom : boolean, the wl1251 has an eeprom connected, which
provides configuration data (calibration, MAC, ...)
- ti,power-gpio : GPIO connected to chip's PMEN pin if operated in
SPI mode
- Please consult Documentation/devicetree/bindings/spi/spi-bus.txt
