3268b5618f [WATCHDOG] Basic support for GE Fanuc's FPGA based watchdog timer
GE Fanuc SBC610

Support for the FPGA based watchdog timer as found on GE Fanuc's SBC310,
SBC610 and PPC9A Single Board Computers.

This patch adds support for the watchdog timer found in one of the devices
FPGAs. There are two identical watchdog timers at different offsets in the
above mentioned boards, this driver is capable of supporting one of them.
The watchdog timers are also capable of generating interrupts at a
user-configurable threshold, though support for this operation is currently
not supported by the driver.

006948bafe [WATCHDOG] Add support for the WM8350 watchdog
This driver implements support for the watchdog functionality provided
by the Wolfson Microelectronics WM8350, a multi-function audio and
power management subsystem intended for use in embedded systems. It is
based on a driver originally written by Graeme Gregory, though it has
been extensively modified since then.

Use of a GPIO to kick the watchdog is not yet supported.

7d8b090661 [WATCHDOG] Add driver for winbond w83697ug/uf watchdog feature
Adapted the w83627hf_wdt.c driver to work with the w83697ug/uf chip, 
found on MSI Fuzzy CX700 boards.

The method used is taken directly from the winbond datasheet and 
surprisingly it differs slightly from all the other winbond watchdogs.

So far it has only been tested on the CX700 board that I have, but it 
seems to work nicely.

28acd02f9f [WATCHDOG] mpc83xx_wdt: rename to mpc8xxx_wdt
Rename the driver because now we support some MPC86xx processors.

There are no changes to the mpc83xx_wdt.c file, yet.  When possible, we do
file renames and changes separately (because Linus once asked so, because
it helps git to track the renamed files).

f606ddf42f remove the v850 port
Trying to compile the v850 port brings many compile errors, one of them exists
since at least kernel 2.6.19.

There also seems to be noone willing to bring this port back into a usable
state.

This patch therefore removes the v850 port.

If anyone ever decides to revive the v850 port the code will still be
available from older kernels, and it wouldn't be impossible for the port to
reenter the kernel if it would become actively maintained again.

7f4da4745c [WATCHDOG] HP ProLiant WatchDog driver
Hp is providing a Hardware WatchDog Timer driver that will only work with the
specific HW Timer located in the HP ProLiant iLO 2 ASIC. The iLO 2 HW Timer
will generate a Non-maskable Interrupt (NMI) 9 seconds before physically
resetting the server, by removing power, so that the event can be logged to
the HP Integrated Management Log (IML), a Non-Volatile Random Access Memory
(NVRAM). The logging of the event is performed using the HP ProLiant ROM via
an Industry Standard access known as a BIOS Service Directory Entry.
