MFD_CORE depends on HAS_IOMEM so anything that selects MFD_CORE should
also depend on HAS_IOMEM since 'select' does not check any dependencies
of the symbol that is being selected.

Pull IIO and staging driver updates from Greg KH:
"Here is the big set of staging and IIO driver updates for 5.15-rc1.
Also included in here are the counter driver subsystem updates as the
IIO drivers needed them.
Lots of churn in some staging drivers, we dropped the "old" rtl8188eu
driver and replaced it with a newer version of the driver that had
been maintained out-of-tree by Larry with the end goal of actually
being able to get this driver out of staging eventually. Despite that
driver being "newer" the line count of this pull request is going up.
Some drivers moved out of staging as well, which is always nice to
see, that is why there are additions to the mfc and misc driver
subsystems. All of these were acked by the various subsystem
maintainers involved.
But by far, as normal, it's coding style cleanups all over the
drivers/staging/ tree in here.
Full details of these changes are in the shortlog.
All of these have been in linux-next for a while with no reported
problems"
[ Note: the r8188eu merge clashed with commit 89939e890605 ("staging:
rtlwifi: use siocdevprivate") from the networking tree. When resolving
the issue, I noted that the whole r8188eu rtw_android code is dead
since commit ae7471cae00a ("staging: r8188eu: remove rtw_ioctl
function").
End result: the merge resolution was to throw all of that away,
rather than do the mindless fixup to code that isn't actually
reachable - Linus ]

General Electric Healthcare's PPD has a secondary processor from
NXP's Kinetis K20 series. That device has two SPI chip selects:
The main interface's behaviour depends on the loaded firmware
and is currently unused.
The secondary interface can be used to update the firmware using
EzPort protocol. This is implemented by this driver using the
kernel's firmware API. The firmware is being flashed into
non-volatile flash memory, so it is enough to flash it once
and not on every boot. Flashing will wear the flash memory
(it has a life time of at least 10k programming cycles). At
the same time only occasional FW updates are expected (like e.g.
a BIOS update). Thus the firmware update is triggered via sysfs
instead of doing it in the driver's probe routine like many
other drivers.

Intel Moorestown and Medfield are quite old Intel Atom based
32-bit platforms, which were in limited use in some Android phones,
tablets and consumer electronics more than eight years ago.
There are no bugs or problems ever reported outside from Intel
for breaking any of that platforms for years. It seems no real
users exists who run more or less fresh kernel on it. The commit
05f4434bc130 ("ASoC: Intel: remove mfld_machine") also in align
with this theory.
Due to above and to reduce a burden of supporting outdated drivers
we remove the support of outdated platforms completely.

Removing the dma and char-misc changes in one patch and

The HiKey 970 board is similar to Hikey 960 with regards
to its USB configutation: it also relies on a USB HUB
that is used when DWC3 is at host mode.
However, it requires a few extra DT settings, as it
uses a voltage regulator and GPIO reset pin.
Add support for them.

The HiKey960 has a fairly complex USB configuration due to it
needing to support a USB-C port for host/device mode and multiple
USB-A ports in host mode, all using a single USB controller.
See schematics here:
https://github.com/96boards/documentation/raw/master/consumer/hikey/hikey960/hardware-docs/HiKey960_Schematics.pdf
This driver acts as a usb-role-switch intermediary, intercepting
the role switch notifications from the tcpm code, and passing
them on to the dwc3 core.
In doing so, it also controls the onboard hub and power gpios in
order to properly route the data lines between the USB-C port
and the onboard hub to the USB-A ports.

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

The only thing that vexpress-syscfg does is provide a regmap to
vexpress-config bus child devices. There's little reason to have 2
components for this. The current structure with initcall ordering
requirements makes turning these components into modules more difficult.
So let's start to simplify things and merge vexpress-syscfg into
vexpress-config. There's no functional change in this commit and it's
still separate components until subsequent commits.

Uacce (Unified/User-space-access-intended Accelerator Framework) targets to
provide Shared Virtual Addressing (SVA) between accelerators and processes.
So accelerator can access any data structure of the main cpu.
This differs from the data sharing between cpu and io device, which share
only data content rather than address.
Since unified address, hardware and user space of process can share the
same virtual address in the communication.
Uacce create a chrdev for every registration, the queue is allocated to
the process when the chrdev is opened. Then the process can access the
hardware resource by interact with the queue file. By mmap the queue
file space to user space, the process can directly put requests to the
hardware without syscall to the kernel space.
The IOMMU core only tracks mm<->device bonds at the moment, because it
only needs to handle IOTLB invalidation and PASID table entries. However
uacce needs a finer granularity since multiple queues from the same
device can be bound to an mm. When the mm exits, all bound queues must
be stopped so that the IOMMU can safely clear the PASID table entry and
reallocate the PASID.
An intermediate struct uacce_mm links uacce devices and queues.
Note that an mm may be bound to multiple devices but an uacce_mm
structure only ever belongs to a single device, because we don't need
anything more complex (if multiple devices are bound to one mm, then
we'll create one uacce_mm for each bond).
uacce_device --+-- uacce_mm --+-- uacce_queue
| '-- uacce_queue

'-- uacce_mm --+-- uacce_queue

The only thing remaining of the machvecs is a few checks if we are
running on an SGI UV system. Replace those with the existing
is_uv_system() check that has been rewritten to simply check the
OEM ID directly.
That leaves us with a generic kernel that is as fast as the previous

The IOC4 is a multi-function chip seen on SGI SN2 and some SGI MIPS
systems. This removes the base driver, which while not having an SN2
Kconfig dependency was only for sub-drivers that had one.

Note this also marks xp broken on ia64 now, as the UV support, which
was disable in generic kernels before actually never compiled due to
undefined uv_gpa_to_soc_phys_ram and uv_gpa_in_mmr_space symbols since

lib/devres.c, which implements devm_ioremap_resource(), is only built
when CONFIG_HAS_IOMEM is set/enabled, so XILINX_SDFEC should depend
on HAS_IOMEM. Fixes this build error (as seen on UML builds):

sd-fec-1.1 device tree node and registers as a character
device, including:
- SD-FEC driver binds to sdfec DT node.
- creates and initialise an initial driver dev structure.
- add the driver in Linux build and Kconfig.

Add support for compaction for VMware balloon. Since unlike the virtio
balloon, we also support huge-pages, which are not going through
compaction, we keep these pages in vmballoon and handle this list
separately. We use the same lock to protect both lists, as this lock is
not supposed to be contended.
Doing so also eliminates the need for the page_size lists. We update the
accounting as needed to reflect inflation, deflation and migration to be
reflected in vmstat.
Since VMware balloon now provides statistics for inflation, deflation
and migration in vmstat, select MEMORY_BALLOON in Kconfig.

'default n' is the default value for any bool or tristate Kconfig
setting so there is no need to write it explicitly.
Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOO
is not set' for visible symbols") the Kconfig behavior is the same
regardless of 'default n' being present or not:
...
One side effect of (and the main motivation for) this change is making
the following two definitions behave exactly the same:
config FOO
bool
config FOO
bool
default n
With this change, neither of these will generate a
'# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied).
That might make it clearer to people that a bare 'default n' is
redundant.

atmel_tclib is probed too late in the boot process to be able to use the
TCB as the boot clocksource. This is an issue for SoCs without the PIT
(sams70, samv70 and samv71 families) as they simply currently can't boot.
Get rid of the atmel_tclib dependency and probe everything on our own using
the correct device tree binding.
This also allows getting rid of ATMEL_TCB_CLKSRC_BLOCK and makes the driver
a bit more flexible as the TCB is not hardcoded in the kernel anymore.

This patch adds basic driver model for Qualcomm FastRPC driver which
implements an IPC (Inter-Processor Communication) mechanism that
allows for clients to transparently make remote method invocations
across processor boundaries.
Each DSP rpmsg channel is represented as fastrpc channel context and
is exposed as a character device for userspace interface.
Each compute context bank is represented as fastrpc-session-context,
which are dynamically managed by the channel context char device.

This driver is a logical device which provides an
interface between the hypervisor and a management
partition. This interface is like a message
passing interface. This management partition
is intended to provide an alternative to HMC-based
system management.
VMC enables the Management LPAR to provide basic
logical partition functions:
- Logical Partition Configuration
- Boot, start, and stop actions for individual
partitions
- Display of partition status
- Management of virtual Ethernet
- Management of virtual Storage
- Basic system management
This driver is to be used for the POWER Virtual
Management Channel Virtual Adapter on the PowerPC
platform. It provides a character device which
allows for both request/response and async message
support through the /dev/ibmvmc node.
