1Broadcom BCM43xx Fullmac wireless SDIO devices
2
3This node provides properties for controlling the Broadcom wireless device. The
4node is expected to be specified as a child node to the SDIO controller that
5connects the device to the system.
6
7Required properties:
8
9 - compatible : Should be "brcm,bcm4329-fmac".
10
11Optional properties:
12 - brcm,drive-strength : drive strength used for SDIO pins on device in mA
13 (default = 6).
14 - interrupt-parent : the phandle for the interrupt controller to which the
15 device interrupts are connected.
16 - interrupts : specifies attributes for the out-of-band interrupt (host-wake).
17 When not specified the device will use in-band SDIO interrupts.
18 - interrupt-names : name of the out-of-band interrupt, which must be set
19 to "host-wake".

23mmc3: mmc@01c12000 {
24 #address-cells = <1>;
25 #size-cells = <0>;
26
27 pinctrl-names = "default";
28 pinctrl-0 = <&mmc3_pins_a>;
29 vmmc-supply = <®_vmmc3>;
30 bus-width = <4>;
31 non-removable;
32 status = "okay";
33
34 brcmf: bcrmf@1 {
35 reg = <1>;
36 compatible = "brcm,bcm4329-fmac";
37 interrupt-parent = <&pio>;
38 interrupts = <10 8>; /* PH10 / EINT10 */
39 interrupt-names = "host-wake";
