+description: >
+ 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.
+
+ For SPI:
+
+ In add of the properties below, please consult
+ Documentation/devicetree/bindings/spi/spi-controller.yaml for optional SPI
+ related properties.

-
-description:
- The WFxxx chip series can be connected via SPI or via SDIO.
-
- For SDIO':'
-
- The driver is able to detect a WFxxx chip on SDIO bus by matching its Vendor
- ID and Product ID. However, driver will only provide limited features in
- this case. Thus declaring WFxxx chip in device tree is recommended (and may
- become mandatory in the future).
-
- In addition, it is recommended to declare a mmc-pwrseq on SDIO host above
- WFx. Without it, you may encounter issues with warm boot. The mmc-pwrseq
- should be compatible with mmc-pwrseq-simple. Please consult
- Documentation/devicetree/bindings/mmc/mmc-pwrseq-simple.yaml for more
- information.
-
- For SPI':'
-
- In add of the properties below, please consult
- Documentation/devicetree/bindings/spi/spi-controller.yaml for optional SPI
- related properties.
-
- Note that in add of the properties below, the WFx driver also supports
- `mac-address` and `local-mac-address` as described in
