c9c68c7177 ath9k: fix issues with external reset on AR913x
An external reset patch for AR955x accidentally led to external reset
being issued twice on AR913x, once before the RTC reset and once after.
This may be causing some stability issues.

00ad43f047 ath9k: remove old rx dma stop check optimization
This commit was added to improve reset time on old SoC devices that run
into chip hangs more frequently. However with the more recent addition
of full WMAC reset on these chips, it could be problematic.
Drop this patch to ensure that DMA activity is really stopped before the
chip reset is issued

b3a871dd3d mac80211: backport "cfg80211: limit scan results cache size"
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."

Signed-off-by: Johannes Berg <johannes.berg@intel.com>"

This patch was added in 4.4.36. But because LEDE backports
cfg80211, mac80211 and the wifi drivers separately, it needs
to be added manually for now. It can be dropped later as it
will be part of the next mac80211 refresh.

448b9b67e1 kernel: mac80211: disable ath9k bands via device tree
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
EEPROM.

These patches will be replaced with a future upstream version which
will introduces an ieee80211 device tree property to disable bands.

3f889418a5 kernel: mac80211: add pending ath9k EEPROM swapping patches
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).

1847248fc1 kernel: mac80211: backport ath9k device tree support patches
These patches add support for configuring ath9k based devices via
devicetree. This was tested on PCI(e) based devices. This should work
for AHB based devices as well (adding more AHB specific properties may
still be needed) as soon as the ath79 platform is ready to populate the
ath9k wmac via devicetree.
This patchset was accepted upstream, more information can be found on

7f235df571 mac80211: rt2x00: remove eeprom filename dependency from mtd-eeprom
The ralink,mtd-eeprom device tree property doesn't require the
ralink,eeprom property to work.

Rework the error handling and user notification as well. Do not log an
error if the mtd-eeprom parameter isn't used. It could be intentional
and should not scare the user.

Check if the number of bytes read from the mtd devices matches the
requested number of bytes.

In case of an mtd read error, give a hint to the user which partition
was tried to read from.

In case everything is fine, notify the user as well.

where the EEPROM filename is required.

Error only out if an EEPROM file is mandatory. Use the
REQUIRE_EEPROM_FILE bit to determine if it is mandatory.

Do not set the REQUIRE_EEPROM_FILE bit while requesting an EEPROM file.
It should be (and is) set before requesting an EEPROM file.
