dt: bindings: add bindings for Broadcom bcm43xx sdio devices
The Broadcom bcm43xx sdio devices are fullmac devices that may be integrated in ARM platforms. Currently, the brcmfmac driver for these devices support use of platform data. This patch specifies the bindings that allow this platform data to be expressed in the devicetree.

+Broadcom BCM43xx Fullmac wireless SDIO devices
+
+This node provides properties for controlling the Broadcom wireless device. The
+node is expected to be specified as a child node to the SDIO controller that
+connects the device to the system.
+
+Required properties:
+
+ - compatible : Should be "brcm,bcm4329-fmac".
+
+Optional properties:
+ - brcm,drive-strength : drive strength used for SDIO pins on device in mA
+ (default = 6).
+ - interrupt-parent : the phandle for the interrupt controller to which the
+ device interrupts are connected.
+ - interrupts : specifies attributes for the out-of-band interrupt (host-wake).
+ When not specified the device will use in-band SDIO interrupts.
+ - interrupt-names : name of the out-of-band interrupt, which must be set
+ to "host-wake".
+
+Example:
+
+mmc3: mmc@01c12000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ pinctrl-names = "default";
+ pinctrl-0 = <&mmc3_pins_a>;
+ vmmc-supply = <&reg_vmmc3>;
+ bus-width = <4>;
+ non-removable;
+ status = "okay";
+
+ brcmf: bcrmf@1 {
+ reg = <1>;
+ compatible = "brcm,bcm4329-fmac";
+ interrupt-parent = <&pio>;
+ interrupts = <10 8>; /* PH10 / EINT10 */
+ interrupt-names = "host-wake";
+ };
+};
