Because some platform Bluetooth will have many background scan when idle.
And the frequently Bluetooth scan will break Wi-Fi traffic many times at
a short duration, it will make Wi-Fi throughput become lower. This patch
will shorter Bluetooth slot and adjust priority settings, make Wi-Fi can
have a more completed duration to do traffic.

Coexistence will set the RF parameter according to Wi-Fi link mode,
Wi-Fi/Bluetooth signal level, traffic direction, antenna type,
and is there Bluetooth connection exist or not. Bluetooth will notify
the current LNA level by scoreboard. If the setting not as expected,
coexistence will try to assign the correct level.

Including Wi-Fi RF mode to judge is Wi-Fi RF still on or off,
if Wi-Fi is RF off should set scoreboard to let Bluetooth know
Wi-Fi has gone. Every time the Wi-Fi radio state changed firmware
should force execute refresh the TDMA coexistence mechanism to
prevent incorrect mechanism runs at mismatch state. The coexistence
antenna/TDMA settings should consider what the Wi-Fi mode it is now,
this can help to solve some LPS transient state issue like A2DP
slightly glitch.

BTG is a RF system type, it means Wi-Fi 2.4GHz and Bluetooth share RF gain
and antenna. The RF gain must control by Wi-Fi or Bluetooth in single side.
For example, if Bluetooth RX a very strong signal, then Bluetooth will
adjust to a lower gain. And Wi-Fi will also use the same gain to do RX,
then maybe the gain will not enough. This BTG control mechanism can do
some refine to this situation.

Pre-AGC(Auto gain control) is a hardware mechanism, it will auto adjust
the RX gain for every packet, it can help to keep Wi-Fi signal on a well
RX quality. The coexistence will give advice to control the API and

Also add function to check register, these registers were monitoring

Trigger a RFK (RF calibration) in firmware by a H2C command, and in
progress it reports log and a result finally by C2H events. Firstly, add
prototype of the C2H event handlers to have a simple picture of framework.
The callers who trigger H2C will wait until a C2H event is received,
so we must process these C2H events in receiving process. Thus, mark this
kind of C2H events as atomic. Also, timestamp is also useful for
debugging, mark C2H events carrying RFK log as atomic as well.

people can classify problems and check if registers values are unexpected,
and then correct them. However, it could possible false alarm because
firmware triggers this SER event by wrong conditions that we should

We add a scanning check to avoid entering IPS after ROC (remain on
channel) during scanning. Additionally, When P2P scanning, the flow is
`1. p2p_listen step` and `2. configure filter` and `3. p2p_scan starts`
in wpas, but in kernel, cfg80211 uses another workqueue to notify driver
the filter change, so sometimes we see (1 > 3 > 2), that will cause Rx
filter related to scan to be cleared. Therefore, we add a scanning check
when configure filter to avoid scan results to be filtered. Finally, we
cancel the ROC delayed workqueue before entering ROC to avoid entering
twice, which might cause leaving ROC too early.

A dynamic mechanism is usually an algorithm to adjust registers to adapt
to different environment every two seconds. In field, it could get
unexpected result, so we need to stop it and adjust registers manually, and
then fine tune the algorithm.
To stop mechanisms to assist debugging, add a debugfs entry shown as
Disabled DM: 0x1
[0] DYNAMIC_EDCCA: X

Add dynamic mechanism EDCCA (Energy Detection Clear Channel Assessment)
in track work. Using a fixed-value threshold will make EDCCA particularly
sensitive and cause failure to transmit under certain circumstances.
Therefore, the threshold is dynamically adjusted to make EDCCA suitable
for any situation.
However, in some cases, we will adjust the EDCCA threshold to the highest
level so that urgent transmissions can be performed successfully, such as
scanning.
Finally, in order to observe the EDCCA report in time, add the EDCCA perIC
register macro and EDCCA HW report analysis. EDCCA logs can be displayed
by using the EDCCA debug mask.

The coming dynamic mechanism of EDCCA adjustment will add a function to
dump registers to reflect status. However, if we are not debugging
the mechanism, we don't print anything, so avoid reading registers by
checking debug mask to reduce IO.

The calibration values of thermal and bias are programmed in invariable
physical map. Read them into driver and will set them to registers later.

Define efuse map struct of RTW89_EFUSE_BLOCK_RF block, and read needed
data from efuse logic map into driver. Also, with efuse power-on state,
read MAC address via register interface according to HCI interface.

Read calibration values of RX gain offset from efuse, and set them to
registers to normalize RX gain for all hardware modules. Then, PHY dynamic
mechanism can get expected values to adjust hardware parameters to yield
expected performance.
