Dear Arend,
I am trying to get a BCM943224HMB module (a Half-Mini Card) [1]
working with the brcmsmac driver.
Broadcom's webpage mentions that the module includes a BCM43224 core
(in addition to a BCM2070 Bluetooth one), but the device is not
getting recognized by the driver in -rc7.
Without understanding too much about AXI, I tried both your
implementation and RafaÅ's (the latter with the addition of my PCI
id). Both did not make the device magically work with brcmsmac, but
with RafaÅ's code I got the following output, telling me that the
device indeed makes use of AXI:
There are two modules for this support. One from Rafal called bcma.ko
and I did one called brcmaxi.ko. I did not get combination brcmsmac/bcma
working yet. So the brcmsmac which is in the linux-next tree does not
need either brcmaxi nor bcma. That is work in progress.

Since you mentioned that you tested brcmaxi with brcmsmac, can you
tell me what's missing to get the device working? Is this only a
question of adding some device IDs to brcmsmac, or does the driver
need some major changes to talk to the core through bcma/brcmaxi? (Or
something completely different?)
As said brcmaxi and bcma are not needed for the current brcmsmac.
thanks for your time,
Gottfried
[1] 14e4:0576, got this with a ThinkPad x120e .. the closed driver
detects the device, but insists that it's disabled by a radio switch
(tested on -rc7)
Let me ask around over here whether adding the device id will work.
