Yes, it does seem to work just fine! The kernel now looks for
brcm/brcmfmac4359c-pcie.sony,kagura-row.bin as we would expect.
So the Sony kagura needs a special brcmfmac firmware like so many
other mobile phones. There are a few Samsungs with custom firmware
as well.
FWIW, Sony did a great job and agreed to license calibration files under
CC0-1.0 [1] and the firmwares itself [2] have a Broadcom license
attached to it.

Arend: what is the legal situation with these custom firmwares?
I was under the impression that Broadcom actually made these,
so they could in theory be given permission for redistribution in
linux-firmware?
Some that I have are newer versions than what is in Linux-firmware,
e.g this from linux-firmware:
brcm/brcmfmac4330-sdio.bin
4330b2-roml/sdio-ag-pool-ccx-btamp-p2p-idsup-idauth-proptxstatus-pno-aoe-toe-pktfilter-keepalive
Version: 5.90.125.104 CRC: 2570e6a3 Date: Tue 2011-10-25 19:34:26 PDT
There is this found in Samsung Codina GT-I8160:
4330b2-roml/sdio-g-p2p-aoe-pktfilter-keepalive-pno-ccx-wepso Version:
5.99.10.0 CRC: 4f7fccf Date: Wed 2012-12-05 01:02:50 PST FWID

Or:
brcmfmac4334-sdio.bin
4334b1min-roml/sdio-ag-pno-p2p-ccx-extsup-proptxstatus-dmatxrc-rxov-pktfilter-keepalive-aoe-vsdb-wapi-wl11d
Version: 6.10.0.0 CRC: 31410dd4 Date: Tue 2012-06-26 11:33:07 PDT FWID

There is this found in Samsung Golden GT-I8190N:
4334b1-roml/sdio-ag-p2p-extsup-aoe-pktfilter-keepalive-pno-dmatxrc-rxov-proptxstatus-vsdb-mchan-okc-rcc-fmc-wepso-txpwr-autoabn-sr
Version: 6.10.58.99 CRC: 828f9174 Date: Mon 2013-08-26 02:13:44 PDT
FWID 01-e39d4d77
So in some cases more than a year newer firmware versions
compared to linux-firmware, I guess also customized for the
phones, but I can't really tell because we don't have anything
of similar date in linux-firmware.
