[ Upstream commit 74f7957c9b1b95553faaf146a2553e023a9d1720 ]
Since debugfs_create_file() return ERR_PTR and never return NULL, so use
IS_ERR() to check it instead of checking NULL.

rtw88: support SAR via kernel common API
Register cfg80211_sar_capa with type NL80211_SAR_TYPE_POWER and four
frequency ranges for configurations in unit of 0.25 dBm. And handle
callback set_sar_specs.
Originally, TX power has three main parameters, i.e. power base,
power by rate, and power limit. The formula can be simply considered
as TX power = power base + min(power by rate, power limit). With the
support of SAR which can be treated as another power limit, there is
one more parameter for TX power. And the formula will evolve into
TX power = power base + min(power by rate, power limit, power sar).
Besides, debugfs tx_pwr_tbl is also refined to show SAR information.
The following is an example for the difference.
Before supporting SAR,
-----------------------------------
...
path rate pwr base (byr lmt ) rem
A CCK_1M 66(0x42) 78 -12 ( 12 -12) 0
A CCK_2M 66(0x42) 78 -12 ( 8 -12) 0
...
-----------------------------------
After supporting SAR and making some configurations,
-----------------------------------
...
path rate pwr base (byr lmt sar ) rem
A CCK_1M 62(0x3e) 78 -16 ( 12 -12 -16) 0

of the TX throughput on the field.
rtw88: add debugfs to fix tx rate
It is useful to fix the bit rate of TX packets. For example, if
someone is measuring the TX power, or debugging with the issues
of the TX throughput on the field.
To set the value of fixed rate, one should input corresponding
desc rate index (ex, 0x0b for DESC_RATE54M to fix at 54 Mbps).
Set a value larger than DESC_RATE_MAX will disable fix rate, so
the rate adaptive mechanism can resume to work.
Example,
To fix rate at MCS 1:
echo 0x0d > /sys/kernel/debug/ieee80211/phy0/rtw88/fix_rate
To not to fix rate:
echo 0xff > /sys/kernel/debug/ieee80211/phy0/rtw88/fix_rate

rtw88: refine fw_crash debugfs to show non-zero while triggering
The usage of fw_crash debugfs is to write 1 to it to trigger fw crash
simulation and to read from it to check the state. When zero is read,
it is supposed to mean fw crash/restart process is done. Then, some
test plans can be designed for crash/restart.
e.g.
step 1. trigger fw crash simulation
step 2. poll the state until zero is read
step 3. check connection by ping test
However, in certain connection cases, triggering fw crash simulation
will take a while. If the state is queried too early before restart
begins processing, it may mistakenly think restart process has been
done. If some tests are started at this time, something unexpected
might happen due to the follow-up restart process.
To avoid that, let fw_crash also show non-zero when a simulation
is still triggering.

rtw88: support adaptivity for ETSI/JP DFS region
Add Energy Detected CCA (EDCCA) mechanism to detect energy on the channel.
And EDCCA support adaptivity mode now. From MIC Ordinance Regulating Radio
Equipment article 49.20, ETSI EN-300-328 and EN-301-893, the device should
be able to dynamically pause TX activity when energy detected on the air.
According to ETSI/JP DFS region, driver will set corresponding threshold
and stop TX activity if the detected energy exceeds the threshold. For now,
we support it on 8822b and 8822c first.
By default, EDCCA mechanism is turned on. For ETSI/JP DFS region, it will
turn to adaptivity mode. However, with adaptivity, if environment is too
noisy, TX may often be halted. So, a debugfs for EDCCA is added. It can
show what EDCCA mode is used currently. And EDCCA mechanism can be turned
on/off through the debugfs while debugging.

rtw88: upgrade rtw_regulatory mechanism and mapping
Mapping table from country code to rtw_regulatory, which manages tx power
limit according to countries, is updated. And mapping architecture is also
upgraded. For more precise control on tx power limit, it allows different
rtw_regulatory for different bands logically. Besides, a helper function
to query rtw_regulatory for current band under current country is provided.
For older chips, some newly added rtw_regulatory may not be configured.
To avoid that those chips have no limit on some countries mapping to a
newer rtw_regulatory after table update, a backward selection mechanism
of rtw_regulatory is introduced. It can help chips use a rtw_regulatory
which has been configured as an alternative of a newer one which is not
configured.
In addition, rtw88 actually doesn't manage channel plans by itself.
Instead, it follows them from stack. So, correct some naming about
chplan with regd, and remove the unnecessary channel control for now.

rtw88: dump FW crash via devcoredump
Use device coredump framework instead of print_hex_dump to support
FW crash dump. Pass data to the framework if preparing and dumping
are successful. The framework will take the ownership of the data.
The data will be freed after the framework determines its lifetime
is over. A new coredump will not work if the previous one still
exists.

use "echo +1 > dm_cap" to enable TXGAPK
use "echo -1 > dm_cap" to disable TXGAPK
Below is an example to disable TXGAPK.

rtw88: 8822c: support FW crash dump when FW crash
Although FW crash logs are already supported for dumping in driver, the
logs may not be sufficient to analyze field issues. To improve this part,
we add a support to dump FW memory.
When driver receives FW crash notifications, driver uses DDMA, which is a
HW ability, to copy specified FW memory to FW fifo. Driver can then dump
these information from FW fifo. With this support, not only FW crash log
but also specified FW memory will be dumped while FW crash. Besides,
specified registers are also dumped.
This feature is implemeted on 8822C first due to difference of FW layouts
between ICs. In addition, we add a debugfs to trigger FW crash. It can
simulate the process of crash, dump and reset. Through it, we can also
check if a reset is ongoing.
