2013-04-10ssb: implement spurious tone avoidanceRafał Miłecki1-0/+2
And make use of it in b43. This fixes a regression introduced with 49d55cef5b1925a5c1efb6aaddaa40fc7c693335 b43: N-PHY: implement spurious tone avoidance This commit made BCM4322 use only MCS 0 on channel 13, which of course resulted in performance drop (down to 0.7Mb/s).

2012-12-14Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linusLinus Torvalds1-0/+3
Pull MIPS updates from Ralf Baechle: "The MIPS bits for 3.8. This also includes a bunch fixes that were sitting in the linux-mips.org git tree for a long time. This pull request contains updates to several OCTEON drivers and the board support code for BCM47XX, BCM63XX, XLP, XLR, XLS, lantiq, Loongson1B, updates to the SSB bus support, MIPS kexec code and adds support for kdump. When pulling this, there are two expected merge conflicts in include/linux/bcma/bcma_driver_chipcommon.h which are trivial to resolve, just remove the conflict markers and keep both alternatives." * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (90 commits) MIPS: PMC-Sierra Yosemite: Remove support.

2012-12-06ssb: add methods for watchdog driverHauke Mehrtens1-2/+3
The watchdog driver wants to set the watchdog timeout in ms and not in ticks, which is depending on the SoC type and the clock. Calculate the number of ticks per millisecond and provide two functions for the watchdog driver. Also return the ticks or millisecond the timer was set to in case the provided value was bigger than the max allowed value. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W.

2012-11-21ssb: add locking around gpio register accessesHauke Mehrtens1-0/+1
The GPIOs are access through some registers in the chip common core or over extif. We need locking around these GPIO accesses, all GPIOs are accessed through the same registers and parallel writes will cause problems.

2012-08-10ssb: check for flash presentenceRafał Miłecki1-1/+3
We can not assume parallel flash is always present, there are boards with *serial* flash and probably some without flash at all. Define some bits by the way.

2010-04-26ssb: do not read SPROM if it does not existJohn W. Linville1-0/+15
Attempting to read registers that don't exist on the SSB bus can cause hangs on some boxes. At least some b43 devices are 'in the wild' that don't have SPROMs at all. When the SSB bus support loads, it attempts to read these (non-existant) SPROMs and causes hard hangs on the box -- no console output, etc. This patch adds some intelligence to determine whether or not the SPROM is present before attempting to read it. This avoids those hard hangs on those devices with no SPROM attached to their SSB bus. The SSB-attached devices (e.g. b43, et al.) won't work, but at least the box will survive to test further patches. :-) Signed-off-by: John W.

2007-10-10[SSB]: add Sonics Silicon Backplane bus supportMichael Buesch1-0/+396
SSB is an SoC bus used in a number of embedded devices. The most well-known of these devices is probably the Linksys WRT54G, but there are others as well. The bus is also used internally on the BCM43xx and BCM44xx devices from Broadcom. This patch also includes support for SSB ID tables in modules, so that SSB drivers can be loaded automatically.
