In the current design, chip entry points are built into
the pci module. That makes the pci module depend on chips.
According to dependence, once the pci module is loaded,
kernel will load chip functionalities, including those that
may not be currently used.
We plan to split chip entry points from the pci module.
Thence we export pci symbols that will be used in chip
entry point modules.

In the current design, various chip functions and tables
are built into rtw88 core. That causes kernel to load its
functionalities even if a chip isn't currently used. We
plan to make each chip's functionalities a separate
kernel module to reduce rtw88 core. And kernel will be
able to load the necessary.
Before extracting chip functionalities, we export symbols
inside rtw88 core which will be used in chip modules.

Seven years ago we tried to fix a leak but actually introduced a double
free instead. It was an understandable mistake because the code was a
bit confusing and the free was done in the wrong place. The "skb"
pointer is freed in both _rtl_usb_tx_urb_setup() and _rtl_usb_transmit().
The free belongs _rtl_usb_transmit() instead of _rtl_usb_tx_urb_setup()
and I've cleaned the code up a bit to hopefully make it more clear.

8723D is a Wifi+BT combo card. To make them work properly, we need coex
mechanism to avoid interference, such as TX simultaneously. Basically,
coex.c provide main algorithm to deal with many use cases, and this commit
adds some parameters and ops differ from other chips, because coex
hardware and WiFi generation are changed.

When chip's temperature is changed, RF characters are changed. To keep the
characters to be consistent, 8723d uses thermal meter to assist in
calibrating LCK, IQK, crystal and TX power.
A base thermal value is programmed in efuse, all calibration data in
MP process is based on this thermal value. So we calucate the delta of
thermal value between the base value, and use this delta to reference XTAL
and TX power offset tables to know how much we need to adjust.
For IQK and LCK, driver checks if delta of thermal value is over 8, then
they are triggered.
For crystal adjustment, when delta of thermal value is changed, we check
XTAL tables to get offset of XTAL value. If thermal value is larger than
base value, positive table (_p as suffix) is used. Otherwise, we use
negative table (_n as suffix). Then, we add offset to XTAL default value
programmed in efuse, and write sum value to register.
To compensate TX power, there are two hierarchical tables. First level use
delta of thermal value to access eight tables to yield delta of TX power
index. Then, plus base TX power index to get index of BB swing table
(second level tables) where register value is induced.
BB swing table can't deal with all cases, if index of BB swing table is
over the size of the table. In this case, TX AGC is used to compensate the
remnant part. Assume 'upper' is the upper bound of BB swing table, and
'target' is the desired index. Then, we can illustrate them as
compensation method BB swing TX AGC
------------------- -------- --------------
target > upper upper target - upper
target < 0 0 target
otherwise target 0
For debug purpose, add a column 'rem' to tx_pwr_tbl entry, and it looks
like
path rate pwr base (byr lmt ) rem
A CCK_1M 32(0x20) 34 -2 ( 0 -2) 0

IQ calibration is used to calibrate RF characteristic to yield expected
performance. Basically, we do calibration twice and compare the similarity
to determine calibration is good or not, if not we do the third
calibration, and then compare with the results of first and second
calibration. If it still not similar, IQK is failed.
Before doing calibration, we need to backup registers that will be
modified in calibration procedure, and restore these registers after
calibration is done.
A calibration procedure can divided into four sub-procedures that are
S1-TX, S1-RX, S0-TX and S0-RX. Where, S1 and S0 represent to path A and B
respectively. Each sub-procedure configure proper registers, and then
rigger one-shot calibration and poll until completion. For RX calibration,
it needs to do twice one-shot calibration, first one is to yield parameter
used by second one.
The result of TX part is stored for TX power tracking that adjusts TX AGC
to output expected power.
