From: Arend van Spriel <[email protected]> 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.
