1 | Broadcom BCM43xx Fullmac wireless SDIO devices |
| 2 | ||
| 3 | This node provides properties for controlling the Broadcom wireless device. The | |
| 4 | node is expected to be specified as a child node to the SDIO controller that | |
| 5 | connects the device to the system. | |
| 6 | ||
| 7 | Required properties: | |
| 8 | ||
| 9 | - compatible : Should be "brcm,bcm4329-fmac". | |
| 10 | ||
| 11 | Optional 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". | |
| 20 | ||
| 21 | Example: | |
| 22 | ||
| 23 | mmc3: 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; | |
