Fix function name in of-fpga-region.c kernel-doc comment

drivers/fpga/of-fpga-region.c:451: warning: expecting prototype for

The FPGA region class driver data structure is being treated as a
managed resource instead of using the standard dev_release call-back
function to release the class data structure. This change removes the
managed resource code and combines the create() and register()
functions into a single register() or register_full() function.
The register_full() function accepts an info data structure to provide
flexibility in passing optional parameters. The register() function
supports the current parameter list for users that don't require the
use of optional parameters.

Currently autoloading for SPI devices does not use the DT ID table, it uses
SPI modalises. Supporting OF modalises is going to be difficult if not
impractical, an attempt was made but has been reverted, so ensure that
module autoloading works for this driver by adding a SPI ID table.

Pull driver core updates from Greg KH:
"Here is the big set of driver core patches for 5.15-rc1.
These do change a number of different things across different
subsystems, and because of that, there were 2 stable tags created that
might have already come into your tree from different pulls that did
the following
- changed the bus remove callback to return void
- sysfs iomem_get_mapping rework
Other than those two things, there's only a few small things in here:
- kernfs performance improvements for huge numbers of sysfs users at
once
- tiny api cleanups
- other minor changes
All of these have been in linux-next for a while with no reported
problems, other than the before-mentioned merge issue"

DFL device drivers have a common need for checking feature revision
information from the DFL header, as well as other common DFL information
like the already exposed feature id and type.
This patch exposes the feature revision information directly via the DFL
device data structure.
Since the DFL core code has already read the DFL header, this this patch
saves additional mmio reads from DFL device drivers too.

The performance reporting driver added cpu hotplug
feature but it didn't add pmu migration call in cpu
offline function.
This can create an issue incase the current designated
cpu being used to collect fme pmu data got offline,
as based on current code we are not migrating fme pmu to
new target cpu. Because of that perf will still try to
fetch data from that offline cpu and hence we will not
get counter data.
Patch fixed this issue by adding pmu_migrate_context call
in fme_perf_offline_cpu function.

This adds the approved PCI Express Device IDs for the Silicom PAC N5010
and N5011 cards (aka. Silicom Lightning Creek cards).
The N5010 features an FPGA that manages/interfaces four QSFP ports, and
allows on-board custom packet processing/filtering/routing, based on
logic loaded with user-provided FPGA bitstreams.
The N5011 cards adds a PCIe switch that exposes, in addition to the FPGA
itself, two Intel E810 (aka Columbiaville) ethernet controllers. With
this, packets can be forwarded from the FPGA to the host for further
processing.

Pull ARM SoC driver updates from Arnd Bergmann:
"Updates for SoC specific drivers include a few subsystems that have
their own maintainers but send them through the soc tree:

- ti-sysc debug option can now detect more devices
- ti-sysc now warns if an old incomplete devicetree data is found as
we now rely on it being complete for am3 and 4
- soc init code needs to check for prcm and prm nodes for omap4/5 and
dra7
- omap-prm driver needs to enable autoidle retention support for
omap4
- omap5 clocks are missing gpmc and ocmc clock registers
- pci-dra7xx now needs to use builtin_platform_driver instead of
using builtin_platform_driver_probe for deferred probe to work
Raspberry Pi:

orderly fashion
- Support for RPi's PoE hat PWM bus
Qualcomm
