ath9k
* add device ID for Toshiba WLM-20U2/GN-1080
* allow more than one interface on DFS channels
bcma
* move flash detection code to ChipCommon core driver
brcmfmac
* IPv6 Neighbor discovery offload
* driver settings that can be populated from different sources
* country code setting in firmware
* length checks to validate firmware events
* new way to determine device memory size needed for BCM4366
* various offloads during Wake on Wireless LAN (WoWLAN)
* full Management Frame Protection (MFP) support
iwlwifi
* add support for thermal device / cooling device
* improvements in scheduled scan without profiles
* new firmware support (-21.ucode)
* add MSIX support for 9000 devices
* enable MU-MIMO and take care of firmware restart
* add support for large SKBs in mvm to reach A-MSDU
* add support for filtering frames from a BA session
* start implementing the new Rx path for 9000 devices
* enable the new Radio Resource Management (RRM) nl80211 feature flag
* add a new module paramater to disable VHT

* Qualcomm Atheros ath10k wireless devices
-For ath10k devices the calibration data can be provided through Device
-Tree. The node is a child node of the PCI controller.
-
Required properties:
--compatible : Should be "qcom,ath10k"
+- compatible: Should be one of the following:
+ * "qcom,ath10k"
+ * "qcom,ipq4019-wifi"
+
+PCI based devices uses compatible string "qcom,ath10k" and takes only
+calibration data via "qcom,ath10k-calibration-data". Rest of the properties
+are not applicable for PCI based devices.
+
+AHB based devices (i.e. ipq4019) uses compatible string "qcom,ipq4019-wifi"
+and also uses most of the properties defined in this doc.
Optional properties:
+- reg: Address and length of the register set for the device.
+- resets: Must contain an entry for each entry in reset-names.
+ See ../reset/reseti.txt for details.
+- reset-names: Must include the list of following reset names,
+ "wifi_cpu_init"
+ "wifi_radio_srif"
+ "wifi_radio_warm"
+ "wifi_radio_cold"
+ "wifi_core_warm"
+ "wifi_core_cold"
+- clocks: List of clock specifiers, must contain an entry for each required
+ entry in clock-names.
+- clock-names: Should contain the clock names "wifi_wcss_cmd", "wifi_wcss_ref",
+ "wifi_wcss_rtc".
+- interrupts: List of interrupt lines. Must contain an entry
+ for each entry in the interrupt-names property.
+- interrupt-names: Must include the entries for MSI interrupt
+ names ("msi0" to "msi15") and legacy interrupt
+ name ("legacy"),
+- qcom,msi_addr: MSI interrupt address.
+- qcom,msi_base: Base value to add before writing MSI data into
+ MSI address register.
- qcom,ath10k-calibration-data : calibration data as an array, the
length can vary between hw versions

- * Note: the brcmfmac can be loaded as module or be statically built-in into

- * module_exit) routines which equal device_initcall. So if you intend to
- * create a module with the platform specific data for the brcmfmac and have
- * it built-in to the kernel then use a higher initcall then device_initcall
- * (see init.h). If this is not done then brcmfmac will load without problems
- * but will not pickup the platform data.
- *
- * When the driver does not "detect" platform driver data then it will continue
- * without reporting anything and just assume there is no data needed. Which is
- * probably true for most platforms.
- *
- * Explanation of the platform_data fields:
- *
- * drive_strength: is the preferred drive_strength to be used for the SDIO
- * pins. If 0 then a default value will be used. This is the target drive
- * strength, the exact drive strength which will be used depends on the
- * capabilities of the device.
- *
- * oob_irq_supported: does the board have support for OOB interrupts. SDIO
- * in-band interrupts are relatively slow and for having less overhead on
- * interrupt processing an out of band interrupt can be used. If the HW
- * supports this then enable this by setting this field to true and configure
- * the oob related fields.
- *
- * oob_irq_nr, oob_irq_flags: the OOB interrupt information. The values are
- * used for registering the irq using request_irq function.
- *
- * broken_sg_support: flag for broken sg list support of SDIO host controller.
- * Set this to true if the SDIO host controller has higher align requirement
- * than 32 bytes for each scatterlist item.
- *
- * sd_head_align: alignment requirement for start of data buffer
- *
- * sd_sgentry_align: length alignment requirement for each sg entry
- *
- * power_on: This function is called by the brcmfmac when the module gets
- * loaded. This can be particularly useful for low power devices. The platform
- * spcific routine may for example decide to power up the complete device.
- * If there is no use-case for this function then provide NULL.
- *
- * power_off: This function is called by the brcmfmac when the module gets
- * unloaded. At this point the device can be powered down or otherwise be reset.
- * So if an actual power_off is not supported but reset is then reset the device
- * when this function gets called. This can be particularly useful for low power
- * devices. If there is no use-case for this function (either power-down or
- * reset) then provide NULL.
- *
- * reset: This function can get called if the device communication broke down.
- * This functionality is particularly useful in case of SDIO type devices. It is
- * possible to reset a dongle via sdio data interface, but it requires that
- * this is fully functional. This function is chip/module specific and this
- * function should return only after the complete reset has completed.

+ * in-band interrupts are relatively slow and for having
+ * less overhead on interrupt processing an out of band
+ * interrupt can be used. If the HW supports this then
+ * enable this by setting this field to true and configure

+ * @oob_irq_nr,

+ * registering the irq using request_irq function.
+ * @broken_sg_support: flag for broken sg list support of SDIO host controller.
+ * Set this to true if the SDIO host controller has higher
+ * align requirement than 32 bytes for each scatterlist
+ * item.
+ * @sd_head_align: alignment requirement for start of data buffer.
+ * @sd_sgentry_align: length alignment requirement for each sg entry.
+ * @reset: This function can get called if the device communication
+ * broke down. This functionality is particularly useful in
+ * case of SDIO type devices. It is possible to reset a
+ * dongle via sdio data interface, but it requires that
+ * this is fully functional. This function is chip/module
+ * specific and this function should return only after the
+ * complete reset has completed.
