The request API provides a way to group buffers and device parameters
into units of work to be queued and executed. This patch introduces the
UAPI and core framework.
This patch is based on the previous work by Laurent Pinchart. The core
has changed considerably, but the UAPI is mostly untouched.
As discussed yesterday, here is a rebase on the media master branch. A
few minor fixes for typos have also slept in, but otherwise this is
equivalent to v2. I expect to have the buffer queueing behavior fixed in
the next version.

The ioeventfd here is actually irqfd handling of an ioeventfd such as

Include the nmistat in the nmi_panic message to give support
an indication why the NMI was called (e.g. a timeout or generate
nmi button.)

Gen8 and prior Proliant systems supported the "CRU" interface
to firmware. This interfaces allows linux to "call back" into firmware
to source the cause of an NMI. This feature isn't fully utilized
as the actual source of the NMI isn't printed, the driver only
indicates that the source couldn't b
The primary purposes of this patch set are to
1) Update the hpwdt driver to use the watchdog core.
2) Reduce complexity by removing unnecessary features.
3) Add customer requested features like optional pretimeout.
4) Enhance readability/maintainability of the driver.

Removed data structures: hpwdt_fops, hpwdt_miscdev, watchdog_device

Modify prior change to not claim an NMI unless originated
from iLO to apply only to iLO5 and later going forward.
This restores hpwdt traditional behavior of calling panic
if the NMI is NMI_IO_CHECK, NMI_SERR, or NMI_UNKNOWN for
legacy hardware.

The intent of this parameter is unclear and it sets up a
race between the reset of the system by ASR and crashdump.
The length of time between receipt of the pretimeout NMI
and the ASR reset of the system is fixed by hardware.
Turning the parameter off doesn't necessairly prevent a crash dump.

Make whether or not the hpwdt watchdog delivers a pretimeout NMI

The underlying iLO hardware is programmable as to whether or not
a pre-timeout NMI is delivered to the system before the iLO resets

Introduce firmware driver for ZynqMP core.
This patchset is adding communication layer with firmware.
Firmware driver provides an interface to firmware APIs.
Interface APIs can be used by any driver to communicate to
PMUFW(Platform Management Unit). All requests go through ATF.
v4:
- Changed cloc
Add documentation to describe Xilinx ZynqMP firmware driver
bindings. Firmware driver provides an interface to firmware
APIs. Interface APIs can be used by any driver to communicate
to PMUFW (Platform Management Unit).

Firmware-debug provides debugfs interface to all APIs.
Debugfs can be used to call firmware APIs with required
parameters.
Usage:
* Calling firmware API through debugfs:
# echo " .. " > /sys/kernel/debug/zynqmp-firmware/pm
* Read output of last called firmware API:
# cat /sys/kernel/debug/zy
