TDMA-based MCC (STA+P2P) is a kind of multiple interfaces concurrence.
Basically, driver is to calculate timeslot pattern and firmware follows
the pattern to switch channels. Since BT-coexistence is also a TDMA-based
mechanism, also consider BT timeslot into pattern if BT devices present.
To easier to review these 20+ patches, I summary basic purpose of these
patches below by group, and submit them by small patchset one by one.
Group 1. get BT timeslot from coex mechanism
Group 2. adjust some stuff related to driver channel context
Group 3. P2P NoA infrastructure to add the IE to beacon when playing GO
Group 4. adjust driver to support 2 channel context
Group 5. calculate timeslot patterns and trigger firmware to switch
channels followed the patterns
Group 6. disable some dynamic tracking mechanism of RF calibration when
MCC is running.
Group 7. monitor states and adjust timeslot patterns. For example, if
BT device leaves, we can reassign the slot to WiFi.
Group 8. Remain-on-channel and hardware scan are related to channel
context, so need some treatments to work with MCC properly.
Group 9. Finally, we declare 8852C to support MCC
This patchset includes groups 1-4 above, and depends on another patch
"wifi: rtw89: Introduce Time Averaged SAR (TAS) feature"
because both modify the same file, not functional dependency.
Zong-Zhe Yang (6):
wifi: rtw89: add function prototype for coex request duration
wifi: rtw89: refine rtw89_correct_cck_chan() by
rtw89_hw_to_nl80211_band()
wifi: rtw89: sar: let caller decide the center frequency to query
wifi: rtw89: call rtw89_chan_get() by vif chanctx if aware of vif
wifi: rtw89: provide functions to configure NoA for beacon update
wifi: rtw89: initialize multi-channel handling
