Hi,
i'm currently working on Raspberry Pi Zero W for Mainline. Here is my first patch series [1].
Unfortunately i didn't get brcmfmac (connected via SDIO) probed with this patch series against 4.12.0-rc5-next-20170616+

I already tried the additional patches from Gerd Hofmann's repo [2], but this didn't improve anything.
Any ideas what could be the problem?
Thanks

after commenting out this line, the issue doesn't appear.

Unfortunately the Pi 3 doesn't have out of the box Wifi support in Mainline. Gerd Hoffmann currently maintains some patches for Wifi support [2]. But they aren't against 4.13-rc1. I could prepare a branch against 4.13-rc1.

i found out that 4.12 didn't have the problem and rebased my changes [3].
Now 4.13-rc1 is out and i bisected the regression:

brcmfmac: add firmware feature detection for gscan feature
Detect gscan support in firmware by doing pfn_gscan_cfg iovar with
invalid version.
Unfortunately this commit cannot be simply reverted and i wasn't sure about the dependencies. So i need to revert the following commits to get it running with 4.13-rc1:
123fef3fd4ae6052bad5cf1623c49845d16a6c67
2526ff21aa77c205f72e8263335f20b7d7e636fc

9fe929aaace6a3019dd64a70063cc7b0bb956a4e
Would be nice to get this fixed.

I am a bit in doubt about this one. We can avoid the firmware config
above for bcm4343x devices as a short term fix. However, I would like to
root cause the issue. Received a Pi Zero over here so gearing it up.

Franky/Arend, if a ZeroW would help now and in future Pi Wifi issues,
I can get one to you. Email me off list.

Can you please try to comment out the following lines in
brcmf_feat_attach? That's the only suspicious line that interact with
firmware in the patch.
+ brcmf_feat_iovar_data_set(ifp, BRCMF_FEAT_GSCAN, "pfn_gscan_cfg",
+ &gscan_cfg, sizeof(gscan_cfg));
I don't have a pi zero w but will try to see if I can reproduce it on a pi 3.
