-The WFxxx chip series can be connected via SPI or via SDIO.
-
-SPI
----
-
-You have to declare the WFxxx chip in your device tree.
-
-Required properties:
- - compatible: Should be "silabs,wf200"
- - reg: Chip select address of device
- - spi-max-frequency: Maximum SPI clocking speed of device in Hz
- - interrupts-extended: Should contain interrupt line (interrupt-parent +
-   interrupt can also been used). Trigger should be `IRQ_TYPE_EDGE_RISING`.
-
-Optional properties:
- - reset-gpios: phandle of gpio that will be used to reset chip during probe.
-   Without this property, you may encounter issues with warm boot.
-   (Legacy: when compatible == "silabs,wfx-spi", the gpio is inverted.)
-
-Please consult Documentation/devicetree/bindings/spi/spi-bus.txt for optional
-SPI connection related properties,
-
-Example:
-
-&spi1 {
-	wfx {
-		compatible = "silabs,wf200";
-		pinctrl-names = "default";
-		pinctrl-0 = <&wfx_irq &wfx_gpios>;
-		interrupts-extended = <&gpio 16 IRQ_TYPE_EDGE_RISING>;
-		wakeup-gpios = <&gpio 12 GPIO_ACTIVE_HIGH>;
-		reset-gpios = <&gpio 13 GPIO_ACTIVE_LOW>;
-		reg = <0>;
-		spi-max-frequency = <42000000>;
-	};
-};
-
-
-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 strongly recommended (and may
-become mandatory in the future).
-
-Required properties:
- - compatible: Should be "silabs,wf200"
- - reg: Should be 1
-
-In addition, it is recommended to declare a mmc-pwrseq on SDIO host above WFx.
-Without it, you may encounter issues with warm boot. mmc-pwrseq should be
-compatible with mmc-pwrseq-simple. Please consult
-Documentation/devicetree/bindings/mmc/mmc-pwrseq-simple.txt for more
-information.
-
-Example:
-
-/ {
-	wfx_pwrseq: wfx_pwrseq {
-		compatible = "mmc-pwrseq-simple";
-		pinctrl-names = "default";
-		pinctrl-0 = <&wfx_reset>;
-		reset-gpios = <&gpio 13 GPIO_ACTIVE_LOW>;
-	};
-};
-
-&mmc1 {
-	mmc-pwrseq = <&wfx_pwrseq>;
-	#address-size = <1>;
-	#size = <0>;
-
-	mmc@1 {
-		compatible = "silabs,wf200";
-		reg = <1>;
-		pinctrl-names = "default";
-		pinctrl-0 = <&wfx_wakeup>;
-		wakeup-gpios = <&gpio 12 GPIO_ACTIVE_HIGH>;
-	};
-};
-
-Note that #address-size and #size shoud already be defined in node mmc1, but it
-is rarely the case.
-
-Common properties
------------------
-
-Some properties are recognized either by SPI and SDIO versions:
- - wakeup-gpios: phandle of gpio that will be used to wake-up chip. Without
-   this property, driver will disable most of power saving features.
- - config-file: Use an alternative file as PDS. Default is `wf200.pds`. Only
-   necessary for development/debug purpose.
- - slk_key: String representing hexadecimal value of secure link key to use.
-   Must contains 64 hexadecimal digits. Not supported in current version.
-
-WFx driver also supports `mac-address` and `local-mac-address` as described in
-Documentation/devicetree/bindings/net/ethernet.txt
