* ssb: chipcommon: fix fall-through annotationGustavo A. R. Silva2018-10-051-1/+1
| | | | | | | | | | | Replace "Fallthough" with a proper "fall through" annotation. This fix is part of the ongoing efforts to enabling -Wimplicit-fallthrough Signed-off-by: Gustavo A. R.

* ssb: Remove SSB_WARN_ON, SSB_BUG_ON and SSB_DEBUGMichael Büsch2018-08-091-4/+4
| | | | | | | | | | | Use the standard WARN_ON instead. If a small kernel is desired, WARN_ON can be disabled globally. Also remove SSB_DEBUG. Besides WARN_ON it only adds a tiny debug check. Include this check unconditionally. Signed-off-by: Michael Buesch <m@bues.ch> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

| | | | | | | | | | | | | Replace the ssb printk wrappers by standard print helpers. Also remove SSB_SILENT. Nobody should use it anyway. Originally submitted by Joe Perches <joe@perches.com>.

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.

| * ssb: add locking around gpio register accessesHauke Mehrtens2012-11-211-7/+59
| | | | | | | | | | | | | | | | | | | | | | 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.

* | ssb: add methods for watchdog driverHauke Mehrtens2012-12-061-1/+46
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* | ssb: set the PMU watchdog if availableHauke Mehrtens2012-12-061-2/+36
| | | | | | | | | | | | | | | | | | | | Some ssb based devices have a PMU and the PMU watchdog register should be used instead of the register in the chip common part, if the device has a PMU. This patch also calculates the maximal number the watchdog could be set to. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* ssb: Handle alternate SSPROM locationLarry Finger2010-06-041-0/+1
| | | | | | | | | | | | | | | | In kernel Bugzilla #15825 (2 users), in a wireless mailing list thread (http://lists.infradead.org/pipermail/b43-dev/2010-May/000124.html), and on a netbook owned by John Linville (http://marc.info/?l=linux-wireless&m=127230751408818&w=4), there are reports of ssb failing to detect an SPROM at the normal location. After studying the MMIO trace dump for the Broadcom wl driver, it was determined that the affected boxes had a relocated SPROM. This patch fixes all systems that have reported this problem.

* ssb: do not read SPROM if it does not existJohn W. Linville2010-04-261-0/+2
| | | | | | | | | | | | | | | | | | | 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.

* [SSB]: add Sonics Silicon Backplane bus supportMichael Buesch2007-10-111-0/+446
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.
