[PATCH v1 0/4] BCM4355/4364/4377 support & identification fixes

[Hector Martin]

Hi all,

This series adds support for the BCM4355, BCM4364, and BCM4377 variants
found on Intel Apple Macs of the T2 era (and a few pre-T2 ones).

The first patch fixes a bunch of confusion introduced when adding
support for the Cypress 89459 chip, which is, as far as I can tell,
just a BCM4355.

The subsequent patches add the firmware names and remaining missing
device IDs, including splitting the BCM4364 firmware name by revision
(since it was previously added without giving thought to the existence
of more than one revision in the wild with different firmwares,
resulting in different users manually copying different incompatible
firmwares as the same firmware name).

None of these devices have firmware in linux-firmware, so we should
still be able to tweak firmware filenames without breaking anyone that
matters. Apple T2 users these days are mostly using downstream trees
with the Asahi Linux WLAN patches merged anyway, so they already know
about this.

Note that these devices aren't fully usable as far as firmware
selection on these platforms without some extra patches to add support
for fetching the required info from ACPI, but I want to get the device
ID stuff out of the way first to move forward.

[PATCH v1 1/4] wifi: brcmfmac: Rename Cypress 89459 to BCM4355

[Hector Martin]

The commit that introduced support for this chip incorrectly claimed it
is a Cypress-specific part, while in actuality it is just a variant of
BCM4355 silicon (as evidenced by the chip ID).

The relationship between Cypress products and Broadcom products isn't
entirely clear, but given what little information is available and prior
art in the driver, it seems the convention should be that originally
Broadcom parts should retain the Broadcom name.

Thus, rename the relevant constants and firmware file. Also rename the
specific 89459 PCIe ID to BCM43596, which seems to be the original
subvariant name for this PCI ID (as defined in the out-of-tree bcmdhd
driver). Also declare the firmware as CLM-capable, since it is.

A bit of a problem here. If Cypress want to support this device, 
regardless how they branded it, they will provide its firmware. Given 
that they initially added it (as 89459) I suppose we should mark it with 
CYW and not WCC. Actually, see my comment below on RAW dev ids.

I would remove all RAW device ids. These should not be observed outside 
chip vendor walls.

Right, I thought we might wind up with this issue. So then the question
becomes: can we give responsibility over PCI ID 0x4415 to Cypress and
mark just that one as CYW (if so it probably makes sense to keep that
labeled CYW89459 instead of BCM43596), and if not, is there some other
way to tell apart Cypress and Broadcom products we can use? I believe
the Apple side firmware is developed by Broadcom, not Cypress.

Note that even if we split by PCI device ID here, we still have a
problem with firmware selection, since that means we're requesting the
same firmware filename for both vendors (since that only tests the chip
ID and revision ID). If Apple is the *only* Broadcom customer using
these chips then we can get away with this, since I can just make sure
the fancy Apple firmware selection will never collide with the vanilla
firmware filename. But if other customers of both companies are both
shipping the same chip with different and incompatible generic firmware,
we need some way to tell them apart.

Ack, I'll remove this one instead of renaming it (or I can just drop all
the existing RAW IDs first in one commit at the head of v2 if you prefer
that).

AFAIK Apple chips are exclusive. The vendor marking was added by recent 
patch series I worked on. So per device id we assign the vendor. If 
needed we can use subvendor or subdevid to separate them appropriately.

Let's drop the existing RAW IDs with a separate patch explaining why ;-)

[PATCH v1 2/4] brcmfmac: pcie: Add IDs/properties for BCM4355

[Hector Martin]

This chip is present on at least these Apple T2 Macs:

* hawaii: MacBook Air 13" (Late 2018)
* hawaii: MacBook Air 13" (True Tone, 2019)

Users report seeing PCI revision ID 12 for this chip, which Arend
reports should be revision C2, but Apple has the firmware tagged as
revision C1. Assume the right cutoff point for firmware versions is
revision ID 11 then, and leave older revisions using the non-versioned
firmware filename (Apple only uses C1 firmware builds).

This bit is not described in the commit message. Can you remind me why 
the driver needs to read OTP?

Apple platforms use a vendor-specific OTP area to store identification
information used to select the right firmware/txcap/clm/nvram blobs. See
6bad3eeab6d3d (already upstream) and the immediately preceding commits
for how this all works.

In principle this should just return gracefully if that part of the OTP
is empty, though when I originally wrote this code we only knew of Apple
platforms using these chips anyway. If you think this might possibly
introduce issues to other platforms using the same chips (e.g. if
reading the OTP fails outright for some reason), we could gate it on the
presence of a valid devinfo->settings->antenna_sku, which would indicate
an Apple platform (since that property is specific to the Apple
firmware-selection process and only populated on those platforms).

[PATCH v1 4/4] brcmfmac: pcie: Perform correct BCM4364 firmware selection

[Hector Martin]

This chip exists in two revisions (B2=r3 and B3=r4) on different
platforms, and was added without regard to doing proper firmware
selection or differentiating between them. Fix this to have proper
per-revision firmwares and support Apple NVRAM selection.

Revision B2 is present on at least these Apple T2 Macs:

kauai:    MacBook Pro 15" (Touch/2018-2019)
maui:     MacBook Pro 13" (Touch/2018-2019)
lanai:    Mac mini (Late 2018)
ekans:    iMac Pro 27" (5K, Late 2017)

And these non-T2 Macs:

nihau:    iMac 27" (5K, 2019)

Revision B3 is present on at least these Apple T2 Macs:

bali:     MacBook Pro 16" (2019)
trinidad: MacBook Pro 13" (2020, 4 TB3)
borneo:   MacBook Pro 16" (2019, 5600M)
kahana:   Mac Pro (2019)
kahana:   Mac Pro (2019, Rack)
hanauma:  iMac 27" (5K, 2020)
kure:     iMac 27" (5K, 2020, 5700/XT)

Fixes: 24f0bd136264 ("brcmfmac: add the BRCM 4364 found in MacBook Pro 15,2")

Hi Hector

Shouldn’t there be a WCC instead of BCA here :

You are right. Thanks for catching that. As Hector is changing that 
entry he can hopefully take care of it.
