brcmfmac: stop watchdog before detach and free everything

2018-08-24T11:26:56+00:00

[ Upstream commit 373c83a801f15b1e3d02d855fad89112bd4ccbe0 ]

Using built-in in kernel image without a firmware in filesystem
or in the kernel image can lead to a kernel NULL pointer deference.
Watchdog need to be stopped in brcmf_sdio_remove

The system is going down NOW!

rsi: Fix 'invalid vdd' warning in mmc

2018-08-06T14:24:38+00:00

[ Upstream commit 78e450719c702784e42af6da912d3692fd3da0cb ]

While performing cleanup, driver is messing with card->ocr
value by not masking rocr against ocr_avail. Below panic
is observed with some of the SDIO host controllers due to
this. Issue is resolved by reverting incorrect modifications
to vdd.

brcmfmac: Add support for bcm43364 wireless chipset

2018-08-06T14:24:36+00:00

[ Upstream commit 9c4a121e82634aa000a702c98cd6f05b27d6e186 ]

Add support for the BCM43364 chipset via an SDIO interface, as used in
e.g. the Murata 1FX module.

The BCM43364 uses the same firmware as the BCM43430 (which is already
included), the only difference is the omission of Bluetooth.

However, the SDIO_ID for the BCM43364 is 02D0:A9A4, giving it a MODALIAS
of sdio:c00v02D0dA9A4, which doesn't get recognised and hence doesn't
load the brcmfmac module. Adding the 'A9A4' ID in the appropriate place
triggers the brcmfmac driver to load, and then correctly use the
firmware file 'brcmfmac43430-sdio.bin'.

the country isn't available and it is still programmed in the EEPROM then
it will cause an error and stop the initialization with:
