brcmfmac: fix regression in parsing NVRAM for multiple devices

2018-08-06T14:18:21+00:00

commit 299b6365a3b7cf7f5ea1c945a420e9ee4841d6f7 upstream. NVRAM is designed to work with Broadcom's SDK Linux kernel which fakes PCI domain 0 for all internal MMIO devices. Since official Linux kernel uses platform devices for that purpose there is a mismatch in numbering PCI domains. There used to be a fix for that problem but it was accidentally dropped during the last firmware loading rework. That resulted in brcmfmac not being able to extract device specific NVRAM content and all kind of calibration problems.

brcmfmac: Add support for bcm43364 wireless chipset

2018-08-03T05:47:53+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'.

brcmfmac: fix firmware request processing if nvram load fails

2018-04-09T15:50:31+00:00

When nvram loading fails a double free occurred. Fix this and reorg the code a little. Fixes: d09ae51a4b67 ("brcmfmac: pass struct in brcmf_fw_get_firmwares()") Reported-by: Dan Carpenter Signed-off-by: Arend van Spriel Signed-off-by: Kalle Valo

brcmsmac: allocate ucode with GFP_KERNEL

2018-03-27T09:09:05+00:00

The brcms_ucode_init_buf() duplicates the ucode chunks via kmemdup() with GFP_ATOMIC as a precondition of wl->lock acquired. This caused allocation failures sometimes as reported in the bugzilla below. When looking at the the real usage, one can find that it's called solely from brcms_request_fw(), and it's obviously outside the lock. Hence we can use GFP_KERNEL there safely for avoiding such allocation errors.

brcmfmac: get rid of brcmf_fw_get_full_name()

The function was pretty minimal and now it is called only from one place so just get rid of it. Signed-off-by: Arend van Spriel Signed-off-by: Kalle Valo

brcmfmac: add extension to .get_fwname() callbacks

2018-03-27T09:04:34+00:00

This changes the bus layer api by having the caller provide an extension. With this the callback can use brcmf_fw_alloc_request() to get the needed firmware name.

brcmfmac: introduce brcmf_fw_alloc_request() function

2018-03-27T09:04:31+00:00

The function brcmf_fw_alloc_request() takes a list of required files and allocated the struct brcmf_fw_request instance accordingly. The request can be modified by the caller before being passed to the brcmf_fw_request_firmwares() function.
