This patch removes the MIC drivers from the kernel tree
since the corresponding devices have been discontinued.
Removing the dma and char-misc changes in one patch and
merging via the char-misc tree is best to avoid any
potential build breakage.

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:

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 84af7a6194 ("checkpatch: kconfig: prefer 'help' over

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

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
+-- uacce_queue

That leaves us with a generic kernel that is as fast as the previous

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 f467c5640c ("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.

Highlights:
- Enable support for memory protection keys aka "pkeys" on Power7/8/9 when
using the hash table MMU.
- Extend our interrupt soft masking to support masking PMU interrupts as well
as "normal" interrupts, and then use that to implement local_t for a ~4x
speedup vs the current atomics-based implementation.
- A new driver "ocxl" for "Open Coherent Accelerator Processor Interface
(OpenCAPI)" devices.
- Support for new device tree properties on PowerVM to describe hotpluggable
memory and devices.
- Add support for CLOCK_{REALTIME/MONOTONIC}_COARSE to the 64-bit VDSO.
- Freescale updates from Scott:
"Contains fixes for CPM GPIO and an FSL PCI erratum workaround, plus a
minor cleanup patch."
As well as quite a lot of other changes all over the place, and small fixes and

as well as a new vboxguest subsystem for the VirtualBox hypervisor

The Texas Instruments DAC7512 has the exact same pinout, programming
interface and power-down modes as the Texas Instruments DAC121S101 and
Analog Devices AD5320, which are already supported by the IIO driver
ad5446.c. Remove the duplicate misc driver.
This requires user space to migrate to the standardized IIO sysfs ABI.
(In other words, it needs to change a filename.)
The IIO driver supports the chip's features more fully, e.g. the ability
to power down the output or choose one of the available powerdown modes.
There is an oddity with the misc driver in that it initializes the SPI
slave to SPI_MODE_0, in contradiction to the datasheet which specifies
that data is latched in on the falling edge, implying that SPI_MODE_1
or SPI_MODE_2 must be used. Another oddity is that Kconfig and the
MODULE_DESCRIPTION() claim the chip has 16-bit resolution although it
actually has 12-bit.

This is typically used to monitor BIOS boot progress by listening
to well-known debug port 80h.
