c69a89fe23 mac80211: ath10k: allow failure getting board id via otp
ath10k tries to fetch board id via otp, but that fails for many chips
like QCA988x, QCA9984 etc. Recent commit cc189c0b7f removed the earlier
hack that had allowed QCA radios to work, as that hack was incompatible
with the new wifi chips being introduced to the source tree.

Restore functionality for the existing wifi chips by modifying the
return value of the 'board id via otp' function to a value that is recognised
as a harmless error, so that name evaluation continues by using the board file.

Patch originally suggested by Christian Lamparter in forum discussion.

09ae540cd4 ath9k: fix power limits on init
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.

79a768a90f ath: do not apply broken power limits with ATH_USER_REGD
If a device uses the default EEPROM code, typically only the main CTLs
are valid, and they do not apply properly when switching to a different
regulatory domain. If the regdomain deviates from the EEPROM one, force
the world roaming regdomain to ensure that power limits are sane

8301e61365 mac80211: Fix race condition leading to wifi interfaces not coming up at boot sometimes.
In the drv_mac80211_setup function, mac80211_interface_cleanup
is called to ask the kernel to delete all existing interfaces
for the phy that is being configured via netlink.

Later in the first function, mac80211_prepare_vif is called to
set up the new interfaces as required.

But sometimes, when mac80211_prepare_vif (and so the relevant
`iw phy x interface add y` command) runs, the kernel might still
be cleaning up the old interface with the same ifname. It usually
takes very few time to do that; possibly a few milliseconds of
sleep in the script after detecting this error condition could be
enough, but the busybox sh does not support sub-second sleep
intervals.

When this happens, iw obviously fails to create the new interface;
and the following message is printed in the system log, followed by
subsequent failure messages from hostapd in case this would have been
an AP interface.

Tue Mar 14 04:21:57 2017 daemon.notice netifd: radio1 (2767): command failed: Too many open files in system (-23)

This was a long-standing issue existing since at least OpenWrt Backfire,
and today I finally managed to debug and (hopefully) solve it.
It was happening very few times on most devices; but it was happening
a lot more frequently on fast platforms with multiple radios, such as
the powerpc-based dual-ath9k-radio tl-wdr4900-v1.

181bc02d2e rt2x00: mt7620: yet another beauty session
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.

9eacb9d7fc rt2x00: mt7620: lots of improvements
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.
