Subject: [PATCH] brcmfmac: add support for BCM43455 with modalias
sdio:c00v02D0dA9BF
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
BCM43455 is a more recent revision of the BCM4345. Some of the BCM43455
got a dedicated SDIO device ID which is currently not supported by
brcmfmac.
Adding the new sdio_device_id to brcmfmac is enough to get the BCM43455
supported because the chip itself is already supported (due to BCM4345
support in the driver).

From 8e290cecdd0178f3d4cf7d463c51dc7e462843b4 Mon Sep 17 00:00:00 2001

Subject: [PATCH] brcmfmac: fix incorrect event channel deduction
brcmf_sdio_fromevntchan() was being called on the the data frame
rather than the software header, causing some frames to be
mischaracterized as on the event channel rather than the data channel.
This fixes a major performance regression (due to dropped packets). With
this patch the download speed jumped from 1Mbit/s back up to 40MBit/s due
to the sheer amount of packets being incorrectly processed.

in cfg80211.c only so make it static and drop from header as well.

Subject: [PATCH] brcmfmac: drop brcmf_bus_detach and inline its code
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Driver used to call brcmf_bus_detach only from one place and it already
contained a check for drvr not being NULL. We can get rid of this extra
function, call brcmf_bus_stop directly and simplify the code.
There also isn't brcmf_bus_attach function which one could expect so it
looks more consistent this way.

This intends to make init/attach process slightly easier to follow.
What driver was doing in brcmf_bus_start wasn't bus specific at all and
function brcmf_bus_stop wasn't undoing things done there. This function
is supposed to be called by bus specific code when the bus is ready.
