Subject: [PATCH] brcmfmac: add support for 43341 chip
This chip was already supported, but seems a device came up giving
a different chip identifier. So adding that effectively mapping to
the same firmware file as for 43340 chip.

Subject: [PATCH] brcmfmac: fix handling ssids in .sched_scan_start() callback
The ssids list in the scheduled scan request were not properly taken
into account when configuring in firmware. The hidden bit was set for
any ssid resulting in active scanning for all. Only set it for ssids
that are in the ssids list.

Subject: [PATCH] brcmfmac: make internal escan more generic
For scheduled scan we initiate an escan in firmware to obtain more
info missing from the scheduled scan notification we get from firmware.
For upcoming functionality this is also required so make it a bit
more generic.

Subject: [PATCH] brcmfmac: use provided channels for scheduled scan
User-space can provide list of channels in the schedule scan request.
This was ignored so all channels supported and allowed by the device
were used. This patch configures the device to use the channels as
listed in the request.

Subject: [PATCH] brcmfmac: remove restriction from .sched_scan_start()
callback
In the .sched_scan_start() callback a condition was checked whether a
normal scan was ongoing. However, there is no need for this check as
it is ok to start the scheduled scan irrespective whether or not a
normal scan is ongoing.

Subject: [PATCH] brcmfmac: use requested scan interval in scheduled scan
User-space can specify the interval for the scheduled scan. This
interval is found in scheduled scan plan. The driver supports only
one plan, which is legacy behaviour.

Subject: [PATCH] brcmfmac: fix scheduled scan result handling for newer chips
The scan results for scheduled scan as retrieved from the device
have changed. A field has been added which is not needed. However,
the appended info is. Luckily they are versioned so check that to
find out the location of the appended data.
