AW-CM256SM wifi card

[mtek]

Hello!

I've seen a couple of threads asking how to get the AW-CM256SM combo wifi/bluetooth module working, but I haven't seen any conclusive cases of a user getting it running yet.  I'm in the same boat myself, but I think I'm making progress towards it.

I'm using Manjaro for ARM, the image specifically for the RockPro64.  I installed brcmfmac from the Arch repositories using yay, as I believe that's the correct driver for the module.  

"dmesg | grep SDIO" gives me this: "[     2.172676] mmc0: new ultra high speed SDF104 SDIO card at address 0001"

"dmesg | grep brcmfmac" returns the following: 
[    8.602310] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43455-sdio for chip BCM4345/6

[    9.641432] brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000): clkctl 0x50

If I am understanding correctly then, the module is being detected on mmc0, and I do have the driver installed, but something isn't configured correctly.  Any ideas on what I need to do next?

Thanks in advance!
