[PATCH 00/11] wifi: rtw89: 8922a: add firmware RF calibrations

[Ping-Ke Shih]

For WiFi 7 chips, we move RF calibrations from driver to firmware. Driver
must trigger them one by one, so add H2C commands to trigger each of them,
and add a C2H event to know the result.

Because H2C commands and C2H event go via PCI ring, we should trigger them
after PCI enabled, so add a chip_ops::rfk_init_late for this purpose.

[PATCH 01/11] wifi: rtw89: rfk: add a completion to wait RF calibration report from C2H event

[Ping-Ke Shih]

The RF calibrations should be executed one by one, so add a completion
to ensure one is finish before next. The report from C2H event contains
state and optional version, and we only check the state for now. We also
care about the time a RF calibration takes, so record start time before
asking firmware to do calibration and get the delta time when receiving
report.

Consider SER recovery, we can't receive C2H event, use half of argument
'ms' as fixed delay that is 2 times of measured maximum time of
calibrations.

[PATCH 02/11] wifi: rtw89: rfk: send channel information to firmware for RF calibrations

[Ping-Ke Shih]

We are going to do RF calibrations in firmware, so driver needs to provide
channel information for calibrations, which can do the same things as
they did in driver.

[PATCH 03/11] wifi: rtw89: rfk: add H2C command to trigger IQK

[Ping-Ke Shih]

IQ signal calibration is a basic and important calibration to yield good RF
performance. Do this calibration on AP channel if we are going to connect.
During scanning phase, it transmits with low data rate, so without IQK
RF performance is still acceptable.

[PATCH 04/11] wifi: rtw89: rfk: add H2C command to trigger RX DCK

[Ping-Ke Shih]

RX DCK is receiver DC calibration. This will calibrate DC offset to
reflect correct received signal strength indicator, so mechanisms like CCA
can have normalized values.

[PATCH 08/11] wifi: rtw89: rfk: add H2C command to trigger TSSI

[Ping-Ke Shih]

TSSI is short for transmitter signal strength indication, which is a
close-loop hardware circuit to feedback actual transmitting power as a
reference to adjust power for next transmission.

When connecting and switching bands or channels, do TSSI calibration and
reset hardware status to output expected power.

[PATCH 09/11] wifi: rtw89: 8922a: rfk: implement chip_ops to call RF calibrations

[Ping-Ke Shih]

Calling RF calibrations when interface up, connection, switching bands and
going to scan.

For 8922AE, RF calibrations are moved to firmware, so use H2C commands to
trigger RF calibrations and wait for a C2H event to indicate completion.
Then, do next RF calibration.

[PATCH 10/11] wifi: rtw89: 8922a: add chip_ops::rfk_init_late to do initial RF calibrations later

[Ping-Ke Shih]

The RF calibrations are moved into firmware, so we trigger calibrations by
H2C commands and wait for C2H completion events. However, these events
can be received only after HCI (i.e. PCI for now) starts, so we should
do initial RF calibrations after that.
