Based on the process of discovery in

that (at least) the PowerCloud System CR5000 was unable to get
working 5GHz wireless (PCIe) because AH_USE_EEPROM was unconditionally
masked out, not only when qca,noeeprom was in the DTS.
This patch moves mask AH_USE_EEPROM into the if ... qca,noeeprom

Registering the GPIO chip without a parent device completely breaks the

As long as boards using the devicetree don't have the gpio-controller
property set for the ath9k node, the unloading of the driver works as
expected.
Register the GPIO chip with the ath9k device as parent only for OF
targets to find a trade-off between the needs of driver developers and

Currently, dynack was only tested upstream using AP/STA mode.
Testing it on IBSS, showed that late-ack detection was broken.
This is caused due to dynack using Association Request/Response
frames for late-ack detection, which IBSS does not use.
Also allowing Authentication frames here solves this.
A second issue also got fixed, which was also seen AP/STA mode:
When a station was added, the estimated value would be exponentially averaged
using 0 as a starting point.
This means that on larger distances, the ack timeout was still not high
enough before synchronizing would run out of late-ack's for estimation.
Fix this by using the initial estimated value as a baseline
and only start averaging in the following estimation rounds.
Test setup:
- 2x identical devices: RB912UAG-5HPnD + 19dB sector
- IBSS
- 2x2 802.11an (ar9340), HT20, long GI
- RSSI's -70 / -71

Most of the implementations behind cfg80211_get_station will not initialize
sinfo to zero before manipulating it. For example, the member "filled",
which indicates the filled in parts of this struct, is often only modified
by enabling certain bits in the bitfield while keeping the remaining bits
in their original state. A caller without a preinitialized sinfo.filled can
then no longer decide which parts of sinfo were filled in by
cfg80211_get_station (or actually the underlying implementations).
cfg80211_get_station must therefore take care that sinfo is initialized to
zero. Otherwise, the caller may tries to read information which was not
filled in and which must therefore also be considered uninitialized. In
batadv_v_elp_get_throughput's case, an invalid "random" expected throughput
may be stored for this neighbor and thus the B.A.T.M.A.N V algorithm may
switch to non-optimal neighbors for certain destinations.

Some ath10k firmware versions allow to access the chip internal a
temperature sensor and allow to reduce the amount of the time when the card
is allowed to send. The latter is required on devices which tend to
overheat.
An userspace service has to read
/sys/class/ieee80211/phy*/device/hwmon/hwmon*/temp1_input regularly and
then decide how much the device has to be throttled. This can be done by
writing to /sys/class/ieee80211/phy*/device/cooling_device/cur_state. By
default it is not throttled (0) but it can be throttled up to 100(%).

|Subject: [PATCH] ath10k: search all IEs for variant before falling back
|Date: Wed, 21 Feb 2018 11:43:39 -0500
|[...]
|This patch fixes the issue by first searching the entire file for the ID
|with variant, and searching for the fallback ID only if that search
|fails. It also includes some code cleanup in the area, as
|ath10k_core_fetch_board_data_api_n() no longer does its own string
|mangling to remove the variant from an ID, instead leaving that job to a
|new flag passed to ath10k_core_create_board_name().
|
|I've tested this patch on a QCA4019 and verified that the driver behaves
|correctly for 1) both fallback and variant BDFs present, 2) only fallback
|BDF present, and 3) no matching BDFs present.

Board Data File (BDF) is loaded upon driver boot-up procedure. The right
board data file is identified on QCA4019 using bus, bmi-chip-id and
bmi-board-id.
The problem, however, can occur when the (default) board data file cannot
fulfill the vendor requirements and it is necessary to use a different
board data file.
This problem was solved for SMBIOS by adding a special SMBIOS type 0xF8.
Something similar has to be provided for systems without SMBIOS but with
device trees. No solution was specified by QCA and therefore a new one has
to be found for ath10k.
The device tree requires addition strings to define the variant name
wifi@a000000 {
status = "okay";
qcom,ath10k-calibration-variant = "RT-AC58U";
};
wifi@a800000 {
status = "okay";
qcom,ath10k-calibration-variant = "RT-AC58U";
};
This would create the boarddata identifiers for the board-2.bin search
* bus=ahb,bmi-chip-id=0,bmi-board-id=16,variant=RT-AC58U
* bus=ahb,bmi-chip-id=0,bmi-board-id=17,variant=RT-AC58U

The tx power applied by set_txpower is limited by the CTL (conformance
test limit) entries in the EEPROM. These can change based on the user
configured regulatory domain.
Depending on the EEPROM data this can cause the tx power to become too
limited, if the original regdomain CTLs impose lowr limits than the CTLs
of the user configured regdomain.
To fix this issue, set the initial channel limits without any CTL
restrictions and only apply the CTL at run time when setting the channel
and the real tx power.

If a device uses the default EEPROM code, typically only the main CTLs

devices on the AHB bus.
This patch also removes 936-ath10k_skip_otp_check.patch
because it breaks the AHB device identification.
"Patch is wrong. I find it frustrating OpenWRT/LEDE doesn't
try to work with upstream on ixing these things right."

So here is another round of improvements for MT7620 WiFi.
This commit fixes a few significant issues related to TX_PWR_CFG_x and
TX_ALC and also makes the code more readable by adding register
descriptions for things added for MT7620 and use the usual bit-field
access macros and the now defined macros instead of plain bit-ops and
magic numbers.
Properly describe EEPROM_TARGET_POWER at word 0x68 (== byte 0xD0) and
thereby fix internal TXALC which would otherwise just read
out-of-bounds of the EEPROM map.
Split-out tx-power/ALC related stuff into an additional function.
Fix VCO calibration, it was carried out properly in the channel
switching but incomplete in the actual VCO calibration function.
Also there is no need to trigger VCO calibration in channel switching,
the VCO calibration function is already being called at this point.
Remove it from channel switching function to avoid redundant code.
The TX power calibration differs significantly from all other
Mediatek/Ralink chips: They finally allow 0.5dB steps stored as 8-bit
values for (almost) each bitrate -- and promptly ran out of space and
for some reason didn't want to change the EEPROM layout. The hence
opted for a scheme of sharing values for some adjecent bitrates and
a highly over-complicated (or obfuscated?) way to populate the
TX_PWR_CFG_x registers with the values stored in the EEPROM.
The code here now looks much less complicated than what you see in the
vendor's driver, however, it does the exact same thing:
bGpwrdeltaMinus is a constant and always TRUE, hence half of the
code was dead. Gpwrdelta is always 0 (rather than using the value read
from the EEPROM). What remains is some very grotesque effort to avoid
0x20, probably some hardware bug related to some misunderstanding of
what a singed 8-bit value is (imagine: if it was a signed 6-bit value
then someone could believe that 0x20 == 0x0). And then they didn't
clean it up once they later on anandonned that whole story of having a
constant offset for 40 MHz channels and just set the offset to be
constant 0 -- there is no effort for avoiding 0x20 for the 20 MHz
values stored in the EEPROM, hence that's probably just a forbidden
value in the EEPROM specs and won't appear anyway...
Anyway, the whole thing felt like solving some college math test
where in the end everything cancels out and the result equals 0 ;)
To make sure that channel bandwidth power compensation really doesn't
need to be taken care of, output a warning when the corresponding
value stored in the EEPROM is non-zero.
Also there is no apparent reason to refrain from initializing RFCSR
register 13, it doesn't fail what-so-ever.

This commit combines all the changes I've made on my staging tree
into a single commit fixing many issues with our patch for MT7620.
First of all, checkpatch.pl revealed numerous code style issues with
the patch, so fix all the white-space and commets. Also use
usleep_range instead of legacy timing and relax timing for VCO
calibration just like the vendor driver does.
Several line programming registers were commented out in the patch.
Originally this came from the features present but disabled by default
in the vendor's driver (RTMP_TEMPERATURE_CALIBRATION and
ADJUST_POWER_CONSUMPTION_SUPPORT). Remove the dead code for now, it can
easily be re-added if we actually intend to support those features.
Move values from mt7620_freqconfig type into the existing rf_channel
struct, this shouldn't be a new typedef and it is possible to use the
existing struct because rf_channel got 4 32-bit fields, so two of the
8-bit values from mt7620_freqconfig can easily be stored in the same
32-bit field.
Map values such that
Rdiv -> rf1
N -> rf2
K -> rf3[0:7]
D -> rf3[8:15]
Ksd -> rf4
This makes the channel switching logic already look a bit more like
what we are used to in rt2x00... Probably many of the read-modify-write
calls could still be replaced by macros intended for that.
iq calibration seems to be identical to RT5592, so just enable it.
Test shows that this improves things quite a lot, datarates went up
by a couple of megabits when running iperf, signal quality seems jumpy
in the first few seconds once a station connencts, the stabelizes on a
value significantly better than what it was before.
Add description to the patch and reference the original OpenWrt commit
by which it was added.
The patch now passes checkpatch.pl and can thus be discussed with the
upstream authors of the rt2x00 driver.

The patch commit states:
"It's possible to make scanning consume almost arbitrary amounts
of memory, e.g. by sending beacon frames with random BSSIDs at
high rates while somebody is scanning.
Limit the number of BSS table entries we're willing to cache to
1000, limiting maximum memory usage to maybe 4-5MB, but lower
in practice - that would be the case for having both full-sized
beacon and probe response frames for each entry; this seems not
possible in practice, so a limit of 1000 entries will likely be
closer to 0.5 MB."

These properties allow overriding the settings from the EEPROM
which indicate whether a band is enabled or not.
Setting this property is only needed when the RF circuit does not
support the 2.4GHz or 5GHz band while it is enabled nevertheless in the

will introduces an ieee80211 device tree property to disable bands.

There are two types of swapping the EEPROM data in the ath9k driver.
Before this series one type of swapping could not be used without the
other.
The first type of swapping looks at the "magic bytes" at the start of
the EEPROM data and performs swab16 on the EEPROM contents if needed.
The second type of swapping is EEPROM format specific and swaps
specific fields within the EEPROM itself (swab16, swab32 - depends on
the EEPROM format).
With this series the second part now looks at the EEPMISC register
inside the EEPROM, which uses a bit to indicate if the EEPROM data
is Big Endian (this is also done by the FreeBSD kernel).
This has a nice advantage: currently there are some out-of-tree hacks
(in OpenWrt and LEDE) where the EEPROM has a Big Endian header on a
Big Endian system (= no swab16 is performed) but the EEPROM itself
indicates that it's data is Little Endian. Until now the out-of-tree
code simply did a swab16 before passing the data to ath9k, so ath9k
first did the swab16 - this also enabled the format specific swapping.
These out-of-tree hacks are still working with the new logic, but it
is recommended to remove them. This implementation is based on a
discussion with Arnd Bergmann who raised concerns about the
robustness and portability of the swapping logic in the original OF
support patch review, see [0].
After a second round of patches (= v1 of this series) neither Arnd
Bergmann nor I were really happy with the complexity of the EEPROM
swapping logic. Based on a discussion (see [1] and [2]) we decided
that ath9k should use a defined format (specifying the endianness
of the data - I went with __le16 and __le32) when accessing the
EEPROM fields. A benefit of this is that we enable the EEPMISC based
swapping logic by default, just like the FreeBSD driver, see [3]. On
the devices which I have tested (see below) ath9k now works without
having to specify the "endian_check" field in ath9k_platform_data (or
a similar logic which could provide this via devicetree) as ath9k now
detects the endianness automatically. Only EEPROMs which are mangled
by some out-of-tree code still need the endian_check flag (or one can
simply remove that mangling from the out-of-tree code).
