* ath9k: remove old rx dma stop check optimizationFelix Fietkau2016-12-271-28/+0
| | | | | | | | | | 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.

* mac80211: backport "cfg80211: limit scan results cache size"Christian Lamparter2016-12-191-0/+150
| | | | | | | | | | | | | | | | | | | | | | | 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.

* kernel: mac80211: disable ath9k bands via device treeMartin Blumenstingl2016-11-291-0/+32
| | | | | | | | | | | | | 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.

* kernel: mac80211: add pending ath9k EEPROM swapping patchesMartin Blumenstingl2016-11-297-0/+1730
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | TI wl18xx and wl12xx are Wi-Fi/Bluetooth combo modules that could be found on different existing boards. But it is possible to get those modules as a separate component and use with existing boards as well as new boards equipped with either module may appear so we remove dependency on OMAP instead we add dependency on MMC because this Wi-Fi module uses SDIO interface.

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

* base-files, mac80211, broadcom-wl: wifi detection and configurationChristian Lamparter2016-11-032-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the wifi detection script is executed as part of the (early) boot process. Pluggable wifi USB devices, which are inserted at a later time are not automatically detected and therefore they don't show up in LuCI. A user has to deal with wifi detection manually, or restart the router. However, the current "sleep 1" window - which the boot process waits for wifi devices to "settle down" - is too short to detect wifi devices for some routers anyway. For example, this can happen with USB WLAN devices on the WNDR4700. This is because the usb controller needs to load its firmware from UBI and initialize, before it can operate. The issue can be seen on a BT HomeHub 5A as well as soon as the caldata are on an ubi volume. This is because the ath9k card has to be initialized by owl-loader first. Which has to wait for the firmware extraction script to retrieve the pci initialization values inside the caldata. This patch moves the wifi configuration to hotplug scripts. For mac80211, the wifi configuration will now automatically run any time a "ieee80211" device is added. Likewise broadcom-wl's script checks for new "net" devices which have the "wl$NUMBER" moniker. Issues with spawning multiple interface configuration - in case the detection script is run concurrently - have been resolved by using a named section for the initial configuration. Concurrent configuration scripts will now simply overwrite the same existing configuration. A workaround which preserves the "sleep 1" window for just the first boot has been added. This allows the existing brcm47xx boot and mvebu uci-default scripts to correctly setup the initial mac addresses and regulatory domain. And finally, the patch renames the "wifi detect" into "wifi config". As the script no longer produces any output that has to be redirected or appended to the configuration file.

* base-files, mac80211, broadcom-wl: use uci to populate wireless configChristian Lamparter2016-11-031-22/+21
| | | | | | | | | | | | | | | | | | | | Previously, wifi detect simply dumped its generated wireless configuration to STDOUT. A second step was needed to append the configuration to /etc/config/wireless (or create it, if it didn't exist). With this patch, The wifi detection script will now use uci to update the wireless configuration directly. This patch also makes the initially created wifi-iface a named section ('default_radio$X' for mac80211 and 'default_wl$X' for broadcom). With this change, uci will not print the cfgHASH to STDOUT (which would now corrupt the wireless configuration). It will also prevent adding duplicated wifi interface configurations, if the wifi configuration is run concurrently. Signed-off-by: Christian Lamparter <chunkeey@gmail.com>
