2014-07-29brcmfmac: Fix OOB interrupt not working for BCM43362Hans de Goede1-0/+16
It has taken me a long long time to get the OOB interrupt working on the AP6210 sdio wifi/bt module found on various Allwinner A20 boards. In the end I found these magic register pokes in the cubietruck kernel tree: https://github.com/cubieboard2/linux-sunxi/commit/7f08ba395617d17e7a711507503d89a50406fe7a This is also done for the bcm43362 in broadcom's internal/proprietary driver.

2013-04-12brcmfmac: define and use platform specific data for SDIO.Hante Meuleman1-77/+78
This patch adds support for platform specific data for SDIO fullmac devices. Currently OOB interrupts are configured by Kconfig BRCMFMAC_SDIO_OOB but that is now determined dynamically by checking availibility of platform data.

2013-04-03brcmfmac: add dedicated log level for low-level sdio debuggingArend van Spriel1-15/+15
The low-level sdio code has a large number of trace and info messages that are mostly useful looking into bus specific issues. For tracing higher-level driver functions it is better to have a dedicated level for low-level sdio debugging.

2013-01-08brcmfmac: define pr_fmt in one placeArend van Spriel1-2/+0
Several source files (but not all) define the pr_fmt() macro in exactly the same way. Instead this commit defines it in a header file so driver logging is consistent.

2012-12-11brcmfmac: error messages should not be suppressedArend van Spriel1-8/+7
The call to brcmf_dbg(ERROR, ...) only resulted in a log message when compiled with -DDEBUG. Error messages are valuable for resolving issues so this patch replaces it with brcmf_err(...) so they always end up in the log.

On sdio module unload followed by load (without removing the device) the access window should be moved back to enumeration space. Force this by removing initialisation of sbwad during probe.
