linux.git/drivers/ssb, branch v3.8-rc2

Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus

2012-12-14T22:27:45+00:00

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."

ssb: use WARN in main.c

2012-12-10T20:47:32+00:00

Use WARN rather than printk followed by WARN_ON(1), for conciseness.

ssb: register watchdog driver

2012-12-06T19:58:58+00:00

Register the watchdog driver to the system if it is a SoC. Using the
watchdog on a non SoC device, like a PCI card, will make the PCI
card die when the timeout expired, but starting it again is not
supported by ssb.

ssb: extif: add methods for watchdog driver

2012-12-06T19:58:58+00:00

The watchdog driver wants to set the watchdog timeout in ms and not in
ticks, add a method converting ms to ticks before setting the watchdog
register. Return the ticks or millisecond the timer was set to in case
the provided value was bigger than the max allowed value.

ssb: extif: add check for max value before setting watchdog register

2012-12-06T19:58:57+00:00

Prevent the watchdog register on the extif core to be set to a too
high value.

ssb: add methods for watchdog driver

2012-12-06T19:58:57+00:00

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.

ssb: set the PMU watchdog if available

2012-12-06T19:58:57+00:00

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.

ssb: get alp clock from devices with PMU

2012-12-06T19:58:57+00:00

If there is a PMU in the device, get the alp clock from that part and
do not assume 20000000.

ssb: extif: fix compile errors

2012-11-30T18:38:14+00:00

If CONFIG_SSB_EMBEDDED or CONFIG_SSB_DRIVER_MIPS is set and
CONFIG_SSB_DRIVER_EXTIF is not set, it will cause compile problems
because of missing functions. This patch fixes these problems.

The mips driver now also uses ssb_chipco_available() instead of
checking bus->chipco.dev manually.

ssb: add GPIO driver

2012-11-21T20:55:52+00:00

Register a GPIO driver to access the GPIOs provided by the chip.
The GPIOs of the SoC should always start at 0 and the other GPIOs could
start at a random position. There is just one SoC in a system and when
they start at 0 the number is predictable.
