brcmsmac and BCM47186 (BCM5357) + brcmfmac and BCM43236 V2

[Hauke Mehrtens]

Hi Arend,

I got a new device, a Linksys E3200 with a BCM47186 (id: 0x5357) and a
BCM43236 v2 for 5GHz wifi.

The BCM47186 has a wifi core rev 28, a N-PHY rev 9 and a 2057 radio rev
5 and it does not work with brcmsmac or b43. :-(

Are there plans to add support for such new N-PHY revs to brcmsmac and
the firmware?

Here are some parts of my log with brcmsamc with firmware from
linux-firmware.

Did you talk to the firmware guys, is there a limitation to core rev 23
devices in the N-PHY firmware other than in the firmware used by wl?

There is also a BCM43236 V2 (usb chip) on the board. I tried brcmfmac
and the firmware from linux-firmware, but it did not work. This is a rev
2 device and brcmfmac just seams to support rev 3. Are there any plans
to add support for rev 2 or is this an other problem and a rev 2 device
should also work with brcmfmac?

We are planning to add support for bcm43227/228. This requires an update
in the n-phy code.

I expect you changed some brcmsmac code allow it to handle your device.
Correct?

I had to dive into the firmware repo myself and the answer is yes. The
published firmware for brcmsmac only supports the corerev of the chips
it currently supports.

There is no fullmac firmware for Rev 1 and 2 as these simply lack
on-chip memory to do so. These devices use a different driver model.
This model has a different split of functionality between device and
host. Neither brcmsmac nor brcmfmac can support devices using that model.

Hauke, is this 0x5357 a SoC bcma, or additional bcma connected via
PCIE to the main one? If it's the second case, could you provide pci
id, please?

Hi Rafał,

0x5357 is a SoC with a ieee80211 core, but no PCIe core, just USB 2.0.
Should I add all the SoC chips I know of to the b43 device list?
