RTW88: Add support for USB/SDIO variants
Add WIP upstream patches to support RTW88 USB and SDIO.
- rebased for 6.0 #6829
These patches are incorporated into the linux/patches/default - and are enabled for USB on both Generic and Samsung. For Allwinner TX6 (which has the rtw8822BS/CS chip) the SDIO Kconfig has been enabled as a module.
The driver is running well on the Tanix TX6 - though there are the following observed issues:
- powersave does look like it needs to be disabled on the TX6:
-
iw wlan0 set power_save off- https://lore.kernel.org/lkml/[email protected]/#t
-
- on suspend and resume the wireless firmware (8822CS) does not reconnect
- refer the the below script to re-establish
- deauthentication status code of 252 with Cisco access points due to session-timeout results in disconnection and manual connection to the wireless is required (this is more likely to be a connman / Cisco "feature".)
- the v9.9.13 firmware is not yet in the mainline linux-firmware. The PRed patches work with both v9.9.11 and v9.9.13 firmware https://github.com/pkshih/linux-firmware/tree/main/rtw88 Driver

- https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/log/
Tested:
- Tanix TX6 with RTL8822BS - @jernejsk
- Tanix TX6 with RTL8822CS - @heitbaum
# cat fix-wireless.sh
rmmod rtw88_8822cs
rmmod rtw88_8822c
rmmod rtw88_sdio
rmmod rtw88_core
rmmod mac80211
modprobe rtw88_8822cs
@heitbaum if (vif->bss_conf.assoc) needs to be changed to if (vif->cfg.assoc) to apply on 6.0
FYI- v5 patches on LKML https://lore.kernel.org/linux-wireless/[email protected]/
There is also another accepted patch that supposedly resolve performance issues: https://patchwork.kernel.org/project/linux-wireless/patch/[email protected]/
Testing w/ rtl8822bu dongle on RPi4 yields device lock ups, so not quite ready. Same experience with the v2 patch set here.
Test running on Tanix TX6
