Commit262f2b53f6("brcmfmac: call brcmf_attach() just before calling brcmf_bus_started()") changed the initialization order of the brcmfmac SDIO driver. Unfortunately since brcmf_sdiod_intr_register() is now called before the sdiodev->bus_if initialization, it reads the wrong chip ID and fails to initialize the GPIO on brcm43362. Thus the chip cannot send interrupts and fails to probe: [ 12.517023] brcmfmac: brcmf_sdio_bus_rxctl: resumed on timeout [ 12.531214] ieee80211 phy0: brcmf_bus_started: failed: -110 [ 12.536976] ieee80211 phy0: brcmf_attach: dongle is not responding: err=-110 [ 12.566467] brcmfmac: brcmf_sdio_firmware_callback: brcmf_attach failed Initialize the bus interface earlier to ensure that brcmf_sdiod_intr_register() properly sets up the OOB interrupt.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
