+* STMicroelectronics SAS. ST21NFCB NFC Controller
+

+- compatible: Should be "st,st21nfcb_i2c".
+- clock-frequency: I²C work frequency.
+- reg: address on the bus
+- interrupt-parent: phandle for the interrupt gpio controller
+- interrupts: GPIO interrupt to which the chip is connected

+- pinctrl-names: Contains only one value - "default".

+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";
+ };
+};
