2016-02-06brcmfmac: sdio: Increase the default timeouts a bitSjoerd Simons1-2/+2
On a Radxa Rock2 board with a Ampak AP6335 (Broadcom 4339 core) it seems the card responds very quickly most of the time, unfortunately during initialisation it sometimes seems to take just a bit over 2 seconds to respond. This results intialization failing with message like: brcmf_c_preinit_dcmds: Retreiving cur_etheraddr failed, -52 brcmf_bus_start: failed: -52 brcmf_sdio_firmware_callback: dongle is not responding Increasing the timeout to allow for a bit more headroom allows the card to initialize reliably. A quick search online after diagnosing/fixing this showed that Google has a similar patch in their ChromeOS tree, so this doesn't seem specific to the board I'm using.

2016-02-06brcmfmac: treat NULL character in NVRAM as separatorRafał Miłecki1-1/+1
Platform NVRAM (stored on a flash partition) has entries separated by a NULL (\0) char. Our parsing code switches from VALUE state to IDLE whenever it meets a NULL (\0). When that happens our IDLE handler should simply consume it and analyze whatever is placed ahead. This fixes harmless warnings spamming debugging output: [ 155.165624] brcmfmac: brcmf_nvram_handle_idle warning: ln=1:col=20: ignoring invalid character [ 155.180806] brcmfmac: brcmf_nvram_handle_idle warning: ln=1:col=44: ignoring invalid character [ 155.195971] brcmfmac: brcmf_nvram_handle_idle warning: ln=1:col=63: ignoring invalid character Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

On Broadcom ARM routers BCM4366 cards are available with 14e4:4365 ID. Unfortunately this ID was already used by Broadcom for cards with BCM43142, a totally different chipset requiring SoftMAC driver.

So far we were looking for address descriptors without a check for crossing current component border. In case of dealing with unsupported descriptor or descriptor missing at all the code would incorrectly get data from another component.

2016-02-06brcmfmac: fix setting primary channel for 80 MHz widthRafał Miłecki1-13/+10
First of all it changes the way we calculate primary channel offset. If we use e.g. 80 MHz channel with primary frequency 5180 MHz (which means center frequency is 5210 MHz) it makes sense to calculate primary offset as -30 MHz. Then it fixes values we compare primary_offset with. We were comparing offset in MHz against -2 or 2 which was resulting in picking a wrong primary channel.

The attached patch removes the call to waitqueue_active() leaving just wake_up() behind. This fixes the problem because the call to spin_lock_irqsave() in wake_up() will be an ACQUIRE operation.

2015-11-30brcmfmac: Unify methods to define and map firmware files.Hante Meuleman6-317/+178
All bus drivers (sdio, usb and pcie) require firmware files which needs to be downloaded to the device, The definitions and mapping of device id and revision to firmware and nvram file is done by each bus driver.

2015-11-30brcmfmac: Change error print on wlan0 existence.Hante Meuleman1-3/+4
During initialization of the device, but also on some other moments the driver prints an error that the netdev already exists. This is a result of the way the driver is initializing the firmware and not really an error. The code is not treating it as an error either. This error print has resulted in many questions by users and is confusing and incorrect. This patch changes the error log into a debug info log.
