+* Silicon Labs Si4455 EASY-TO-USE, LOW-CURRENT OOK/(G)FSK SUB-GHZ TRANSCEIVER
+
+Required properties:
+- compatible: Should be one of the following:
+  - "silabs,si4455" for Silicon Labs Si4455-B1A or Si4455-C2A (driver automatically detects the part info),
+  - "silabs,si4455b1a" for Silicon Labs Si4455-B1A,
+  - "silabs,si4455c2a" for Silicon Labs Si4455-C2A,
+- reg: SPI chip select number.
+- interrupts: Specifies the interrupt source of the parent interrupt
+  controller. The format of the interrupt specifier depends on the
+  parent interrupt controller.
+- clocks: phandle to the IC source clock (only external clock source supported).
+- spi-max-frequency: maximum clock frequency on SPI port
+- shdn-gpios: gpio pin for SDN
+
+Example:
+
+/ {
+	clocks {
+                si4455_1_2_osc: si4455_1_2_osc {
+                        compatible = "fixed-clock";
+                        #clock-cells = <0>;
+                        clock-frequency  = <30000000>;
+                };
+	};
+};
+
+&spi0 {
+	si4455: si4455@0 {
+		compatible = "silabs,si4455";
+		reg = <0>;
+		clocks = <&si4455_1_2_osc>;
+		interrupt-parent = <&gpio>;
+		interrupts = <7 IRQ_TYPE_LEVEL_LOW>;
+                shdn-gpios = <&gpio 26 1>;
+                status = "okay";
+                spi-max-frequency = <3000000>;
+	};

I said I wasn't going to take this into drivers/staging/ so why is this still here?
