Subject: [PATCH] brcmfmac: change function name for
brcmf_cfg80211_wait_vif_event_timeout()
Dropping the '_timeout' from the function name as the fact that a timeout
value is passed makes it obvious a timeout is used. Also helps to keep code
lines a bit shorter and easier to stick to 80 char boundary.

Subject: [PATCH] brcmfmac: Limit memory allocs to <64K
Some systems have problems with allocating memory allocation larger
then 64K. Often on unload/load or suspend/resume a failure is
reported: Could not allocate wiphy device. This patch makes the
escan intermediate storage buf dynamically allocated, and smaller
than 64K.

Subject: [PATCH] brcmfmac: Configure country code using device specific
settings
Country code configuration in a device is a device specific
operation. For this the country code as specified by reg notifier
(iso3166 alpha2) needs to be translated to a device specific
country locale and revision number. This patch adds this
translation and puts a placeholder in the device specific settings
where the translation table can be stored. Additional patches will
be needed to read these tables from for example device platform
data.

Subject: [PATCH] brcmfmac: use device memsize config from fw if defined
Newer type pcie devices have memory which get shared between fw and
hw. The division of this memory is done firmware compile time. As a
result the ramsize as used by driver needs to be adjusted for this.
This is done by reading the memory size from the firmware.

Subject: [PATCH] brcmfmac: use bar1 window size as provided by pci subsystem
The PCIE bar1 window size is specified by chip. Currently the
ioremap of bar1 was using a define which always matched the size
of bar1, but newer chips can have a different bar1 sizes. With
this patch the ioremap will be called with the by chip provided
window size.

Subject: [PATCH] brcmfmac: increase timeout for tx eapol
When keys get set and updated this has to happen after eapol got
transmitted (without key or old key) before the key can be updated.
To make sure the order of sending eapol and configuring key is done
correctly a timeout for tx of eapol is applied. This timeout is set
to 50 msec, which is not always enough. Especially in AP mode and
key updates the timeout may need to be much longer because client(s)
can be in powersave. Increase the timeout from 50 to 950 msec.

Subject: [PATCH] brcmfmac: keep ARP and ND offload enabled during WOWL
Currently ARP and ND (IPv6 Neigbor Discovery) offload get disabled
on entering suspend. However when firmwares support the wowl_cap
iovar then these offload routines can be kept enabled as they
will work during WOWL as well.

Subject: [PATCH] brcmfmac: switch to new platform data
Platform data is only available for sdio. With this patch a new
platform data structure is being used which allows for platform
data for any device and configurable per device. This patch only
switches to the new structure and adds support for SDIO devices.

- * 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.

Subject: [PATCH] brcmfmac: merge platform data and module paramaters
Merge module parameters and platform data in one struct. This is the
last step to move to the new platform data per device. Now parameters
of platform data will be merged with module parameters per device.

Subject: [PATCH] brcmfmac: integrate add_keyext in add_key
brcmf_add_keyext is called when a key is configured for a specific
mac address. This function is very similar to the calling function
brcmf_add_key. Integrate this function and also use existing del_key
function in case key is to be cleared.
