Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

Some devices like TP-Link TL-WN722N produces this kind of messages
frequently.
kernel: ath: phy0: Short RX data len, dropping (dlen: 4)
This warning is useful for developers to recognize that the device
(Wi-Fi dongle or USB hub etc) is noisy but not for general users. So
this patch make this warning to debug message.

ADC & I/Q calibrations could take infinite time to comple, since they
depend on received frames. In particular the I/Q mismatch calibration
requires receiving of OFDM frames for completion. But in the 2.4GHz
band, a station could receive only CCK frames for a very long time.
And while we wait for the completion of one of the mentioned
calibrations, the NF calibration is blocked. Moreover, in some
environments, I/Q calibration is unable to complete until a correct
noise calibration will be performed due to AGC behaviour.
In order to avoid delaying NF calibration on forever, limit the maximum
duration of ADCs & I/Q calibrations. If the calibration is not completed
within the maximum time, it will be interrupted and a next calibration
will be performed. The code that selects the next calibration has been
reworked to the loop so incompleted calibration will be respinned later.
Ð maximum calibration time of 30 seconds was selected to give the
calibration enough time to complete and to not interfere with the long
(NF) calibration.
Run tested with AR9220.

Previously after the calibration validity period is over,
calibrations are invalidated in a one at time manner. So, for AR9002
family, which has three calibrations, the full recalibration interval
becomes 3 x ATH_RESTART_CALINTERVAL. And each next calibration will be
separated by the ATH_RESTART_CALINTERVAL time from a previous one.
It seems like it is better to do whole recalibration at once. Also, this
change makes the driver behaviour a little simpler. So, invalidate all
calibrations at once at the end of the calibration validity interval.
This change affects only AR9002 chips family, since the AR9003 utilize
only a single calibration.

NF calibration and other elements of long calibration are usually faster
than ADCs & I/Q calibrations due to independence of receiption of the
OFDM signal. Moreover sometime I/Q calibration can not be completed at
all without preceding NF calibration. This is due to AGC, which has a
habit to block a weak signal without regular NF calibration. Thus, we do
not need to deferr the long calibration forever.
So, if the long calibration is requested, then deferr the ADCs & I/Q
calibration(s) and run the longcal (the NF calibration in particular) to
obtain fresh noise data.
Run tested with AR9220.

Each of AGC & I/Q calibrations can take a long time. Long calibration
and NF calibration in particular are forbiden for parallel run with
ADC & I/Q calibrations. So, the chip could not be ready to perform the
long calibration at the time of request. And a request to perform the
long calibration may be lost.
In order to fix this, preserve the long calibration request as a
calibration state flag and restore the long calibration request each
time the calibration function is called again (i.e. on each subsequent
ivocation of the short calibration).
This feature will be twice useful after the next change, which will
make it possible to start the long calibration before all ADCs & I/Q
calibrations are completed.

ADC calibration is only required for a 80 MHz sampling rate (i.e. for
40 MHz channels), when the chip utilizes the pair of ADCs in interleved
mode. Calibration on a 20 MHz channel will never be completed.
Previous channel check is trying to exclude all channels where the
calibration will get stuck. It effectively blocks the calibration run
for HT20 channels, but fails to exclude 20 MHz channels without HT (e.g.
legacy mode channels).
Fix this issue by reworking the channel check to explicitly allow ADCs
gain & DC offset calibrations for HT40 channels only. Also update the
complicated comment to make it clear that these calibrations are for
multi-ADC mode only.
Stuck ADCs calibration blocks the NF calibration, what could make it
impossible to work in a noisy evironment: too big Rx attentuation,
invalid RSSI value, etc. So this change is actually more of a NF
calibration fix rather then the ADC calibration fix.
Run tested with AR9220.

ath.git patches for v5.7. Major changes:
ath10k
* support for getting btcoex settings from Device Tree
* support QCA9377 SDIO device
ath11k
* add HE rate accounting
* add thermal sensor and cooling devices
When TPC is disabled IEEE80211_CONF_CHANGE_POWER event can be handled to
reconfigure HW's maximum txpower.
This fixes 0dBm txpower setting when user attaches to an interface for
the first time with the following scenario:
ieee80211_do_open()
ath9k_add_interface()
ath9k_set_txpower() /* Set TX power with not yet initialized
sc->hw->conf.power_level */
ieee80211_hw_config() /* Iniatilize sc->hw->conf.power_level and
raise IEEE80211_CONF_CHANGE_POWER */
ath9k_config() /* IEEE80211_CONF_CHANGE_POWER is ignored */
This issue can be reproduced with the following:
$ modprobe -r ath9k
$ modprobe ath9k
$ wpa_supplicant -i wlan0 -c /tmp/wpa.conf &
$ iw dev /* Here TX power is either 0 or 3 depending on RF chain */
$ killall wpa_supplicant
$ iw dev /* TX power goes back to calibrated value and subsequent
calls will be fine */

With multiple VIFS ath10k, and probably others, tries to find the
minimum txpower for all vifs and uses that when setting txpower in
the firmware.
If a second vif is added and starts to scan, it's txpower is not
initialized yet and it set to zero.
ath10k had a patch to ignore zero values, but then it is impossible
to actually set txpower to zero.
So, instead initialize the txpower to INT_MIN in mac80211, and let
drivers know that means the power has not been set and so should
be ignored.
This should fix regression in:

There really is no need to make drivers call the

Add a new return value (that was previously considered

only drivers that remain different are the Intel ones
as they need to negotiate more with the firmware.

In ath9k_wmi_cmd, the allocated network buffer needs to be released
if timeout happens. Otherwise memory will be leaked.

Atheros cards with a AR92XX generation (and older) chip usually
store their pci(e) initialization vectors on an external eeprom chip.
However these chips technically don't need the eeprom chip attached,
the AR9280 Datasheet in section "6.1.2 DEVICE_ID" describes that
"... if the EEPROM content is not valid, a value of 0xFF1C returns
when read from the register". So, they will show up on the system's
pci bus. However in that state, ath9k can't load, since it relies
on having the correct pci-id, otherwise it doesn't know what chip it
actually is. This happens on many embedded devices like routers
and accesspoint since they want to keep the BOM low and store the
pci(e) initialization vectors together with the calibration data
on the system's FLASH, which is out of reach of the ath9k chip.
Furthermore, Some devices (like the Cisco Meraki Z1 Cloud Managed
Teleworker Gateway) need to be able to initialize the PCIe wifi device.
Normally, this should be done as a pci quirk during the early stages of
booting linux. However, this isn't possible for devices which have the
init code for the Atheros chip stored on NAND in an UBI volume.
Hence, this module can be used to initialize the chip when the
user-space is ready to extract the init code.
Martin Blumenstingl prodived the following fixes:
owl-loader: add support for OWL emulation PCI devices
owl-loader: don't re-scan the bus when ath9k_pci_fixup failed
owl-loader: use dev_* instead of pr_* logging functions
owl-loader: auto-generate the eeprom filename as fallback
owl-loader: add a debug message when swapping the eeprom data
owl-loader: add missing newlines in log messages

In commit 3c0efb745a17 ("ath9k: discard undersized packets")
the lower bound of RX packets was set to 10 (min ACK size) to
filter those that would otherwise be treated as invalid at
mac80211.
Alas, short radar pulses are reported as PHY_ERROR frames
with length set to 3. Therefore their detection stopped
working after that commit.
NOTE: ath9k drivers built thereafter will not pass DFS
certification.
This extends the criteria for short packets to explicitly
handle PHY_ERROR frames.
