Commit 262f2b53f679 ("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.

A workaround [1] disabling the OOB interrupt is being discussed. It
works for me, but this patch fixes the wifi problem on my cubietruck.

I missed that one. Too bad it was not sent to linux-wireless as well. Good
find here. I did see another patch dealing with the OOB interrupt on Nvidia
Tegra. Now I wonder if this is the same issue.

I haven't seen any driver probe failures due to OOB on NVIDIA Tegra,
only suspend-resume was problematic due to the unbalanced OOB
interrupt-wake enabling.
But maybe checking whether OOB interrupt-wake works by invoking
enable_irq_wake() during brcmf_sdiod_intr_register() causes trouble for
the cubietruck board.
@Jean-Philippe, could you please try this change (on top of recent
linux-next):

Sorry for the delay, linux-next doesn't boot for me at the moment and I
have little time to investigate why, so I might retry closer to the merge
window.
However, isn't the interrupt-wake issue independent from the problem
(introduced in v4.17) that my patch fixes? I applied "brcmfmac: Keep OOB
wake-interrupt disabled when it shouldn't be enabled" on v5.5-rc5 and it
doesn't seem to cause a regression, but the wifi only works if I apply my
patch as well.
Thanks,
Jean

Hello Jean,
Could you please clarify whether you applied [1] and then the above
snippet on top of it or you only applied [1] without the snippet?
