linux-toradex.git/include/linux/bcma/bcma_driver_chipcommon.h, branch v3.8.4

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."

bcma: register watchdog driver

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

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

bcma: add methods for watchdog driver

2012-12-06T19:58:56+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.

bcma: 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.

bcma: add bcma_chipco_gpio_pull{up,down}

2012-11-21T20:55:51+00:00

Add functions to access the GPIO registers for pullup and pulldown.
These are needed for handling gpio registration.

bcma: add locking around GPIO register accesses

2012-11-21T20:55:51+00:00

The GPIOs are access through some registers in the chip common core.
We need locking around these GPIO accesses, all GPIOs are accessed
through the same registers and parallel writes will cause problems.

bcma: mark nflash if it is the boot flash

2012-10-19T19:52:37+00:00

There are some devices which are able to boot from nand flash and other
are using a serial flash for booting. Add a bool to indicate that the
device is booted from that flash chip and not from some other chip also
connected to the SoC. This is needed to find the nvram, as it is stored
on the flash the devices booted from.

bcma: just do the necessary things in early register on SoCs

2012-10-19T19:52:18+00:00

Some parts of the initialization for chip common and the pcie core are
accessing the sprom struct, but it is not initialized at that stage.
Just do the necessary thing in the early register on SoCs and not the
complete initialization to read out the nvram from the flash chip.
After it is possible to read out the nvram, the sprom should be parsed
from it and the full initialization of the cores should be run.

mtd: basic (read only) driver for BCMA serial flash

2012-09-29T14:39:12+00:00

This registers MTD driver for serial flash platform device. Right now it
supports reading only, writing still has to be implemented.

Artem: minor amendments.
