This patch modified set_cs_timing parameter, no need pass in spi_delay
to set_cs_timing callback.
By the way, we modified the mediatek and tegra114 spi driver to fix build err.
In mediatek spi driver, We have support set absolute time not clk_count,
and call this function in prepare_message not user's API.

As we know, spi core layer has removed spi_set_cs_timing() API.
So this patch moved spi_delay for cs_timing from spi_controller
to spi_device, because cs timing should be set by spi_device but
not controller.

Extend IS_MODULE() and IS_ENABLED comments to explain why one might use
"#if IS_ENABLED(CONFIG_FOO)" instead of "#ifdef CONFIG_FOO".
To wit, "#ifdef CONFIG_FOO" is true only for CONFIG_FOO=y, while
"#if IS_ENABLED(CONFIG_FOO)" is true for both CONFIG_FOO=y and
CONFIG_FOO=m.
This is because "CONFIG_FOO=m" in .config does not result in "CONFIG_FOO"
being defined. The actual definitions are in autoconf.h, where:
CONFIG_FOO=y results in #define CONFIG_FOO 1
CONFIG_FOO=m results in #define CONFIG_FOO_MODULE 1

git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull more s390 updates from Vasily Gorbik:
- Fix preempt_count initialization.
- Rework call_on_stack() macro to add proper type handling and avoid
possible register corruption.
- More error prone "register asm" removal and fixes.
- Fix syscall restarting when multiple signals are coming in. This adds
minimalistic trampolines to vdso so we can return from signal without
using the stack which requires pgm check handler hacks when NX is
enabled.
- Remove HAVE_IRQ_EXIT_ON_IRQ_STACK since this is no longer true after
switch to generic entry.
- Fix protected virtualization secure storage access exception
handling.
- Make machine check C handler always enter with DAT enabled and move
register validation to C code.
- Fix tinyconfig boot problem by avoiding MONITOR CALL without
CONFIG_BUG.
- Increase asm symbols alignment to 16 to make it consistent with
compilers.
- Enable concurrent access to the CPU Measurement Counter Facility.
- Add support for dynamic AP bus size limit and rework ap_dqap to deal
with messages greater than recv buffer.

Commit cf6acb8bdb1d ("s390/cpumf: Add support for complete counter set extraction")
allows access to the CPU Measurement Counter Facility via character
device /dev/hwctr. The access was exclusive via this device or
via perf_event_open() system call. Only one path at a time was
permitted. The CPU Measurement Counter Facility device driver blocked
access to other processes.
This patch removes this restriction and allows concurrent access to
the CPU Measurement Counter Facility from multiple processes at the same
time via perf_event_open() SVC and via /dev/hwctr device. The access
via /dev/hwctr device is still exclusive, only one process is allowed to
access this device.
This patch
- moves the /dev/hwctr device access from file perf_cpum_cf_diag.c.
to file perf_cpum_cf.c.
- use only one trace buffer .../s390dbf/cpum_cf.
- remove cfset_csd structure and includes its members it into the
structure cpu_cf_events. This results in one data structure and
simplifies the access.
- rework function familiy ctr_set_enable, ctr_set_disable, ctr_set_start
and ctr_set_stop which operate on a counter set number.
Now they operate on a counter set bit mask.
- move CF_DIAG event functionality to file perf_cpum_cf.c. It now
contains the complete functionality of the CPU Measurement Counter
Facility:
- Performance measurement support for counters using perf stat.
- Support for complete counter set extraction with device /dev/hwctr.
- Support for counter set extraction event CF_DIAG attached to
samples using perf record.
- removes file perf_cpum_cf_diag.c

Memory controller drivers for v5.14 - Tegra SoC, part two
Second set of changes for Tegra SoC memory controller drivers,
containing patchset from Thierry Reding:
"The goal here is to avoid early identity mappings altogether and instead
postpone the need for the identity mappings to when devices are attached
to the SMMU. This works by making the SMMU driver coordinate with the
memory controller driver on when to start enforcing SMMU translations.
This makes Tegra behave in a more standard way and pushes the code to
deal with the Tegra-specific programming into the NVIDIA SMMU
implementation."
This pulls a dependency from Will Deacon (ARM SMMU driver) and contains
further ARM SMMU driver patches to resolve complex dependencies between
different patchsets. The pull from Will contains only one patch
("Implement ->probe_finalize()"). Further work in Will's tree might
depend on this patch, therefore patch was applied there.
On the other hand, this ("Implement ->probe_finalize()") patch is also a
dependency for ARM SMMU driver changes for Tegra. These changes,
bringing seamless transition from the firmware framebuffer to the OS
framebuffer, depend on earlier Tegra memory controller driver patches.

Instead of programming all SID overrides during early boot, perform the
operation on-demand after the SMMU translations have been set up for a
device. This reuses data from device tree to match memory clients for a
device and programs the SID specified in device tree, which corresponds
to the SID used for the SMMU context banks for the device.

The Tegra210 (and earlier) driver now supports all the functionality
that the Tegra186 (and later) driver does, so they can be unified.
Note that previously the Tegra186 (and later) driver could be unloaded,
even if that was perhaps not very useful. Older chips don't support that
yet, but once they do this code can be reenabled.

Tegra20 requires a slightly different interrupt handler than Tegra30 and
later, so parameterize the handler, so that each SoC implementation can
provide its own.

The current per-SoC setup code runs at a fairly arbitrary point during
probe, thereby making it less flexible for other SoC generations. Move
the call around slightly (after only the very basic, common setup that
applies to all SoC generations has been performed), which will allow

Subsequent patches will introduce further callbacks, so create a new

existing ->init() callback into the new structure.

As another step towards unifying both the Tegra210 (and earlier) and
Tegra186 (and later) memory controller drivers, unify the structures
that are used to represent them.
Note that this comes at a slight space penalty since some fields are
not used on all generations, but the benefits of unifying the driver
outweigh the downsides.

Arm Firmware Framework for ARMv8-A(FFA) interface driver
The Arm FFA specification describes a software architecture to
leverages the virtualization extension to isolate software images
provided by an ecosystem of vendors from each other and describes
interfaces that standardize communication between the various software
images including communication between images in the Secure world and
Normal world. Any Hypervisor could use the FFA interfaces to enable
communication between VMs it manages.
The Hypervisor a.k.a Partition managers in FFA terminology can assign
system resources(Memory regions, Devices, CPU cycles) to the partitions
and manage isolation amongst them.
This is the initial and minimal support for the FFA interface to enable
communication between secure partitions and the normal world OS.

Most of the MEM_* APIs share the same parameters, so they can be
generalised. Currently only MEM_SHARE is implemented and the user space
interface for that is not added yet.

Parse the FFA nodes from the device-tree and register all the partitions
whose services will be used in the kernel.
In order to also enable in-kernel users of FFA interface, let us add
simple set of operations for such devices.
The in-kernel users are registered without the character device interface.

The Arm FF for Armv8-A specification has concept of endpoints or
partitions. In the Normal world, a partition could be a VM when
the Virtualization extension is enabled or the kernel itself.
In order to handle multiple partitions, we can create a FFA device for
each such partition on a dedicated FFA bus. Similarly, different drivers
requiring FFA transport can be registered on the same bus. We can match
the device and drivers using UUID. This is mostly for the in-kernel
users with FFA drivers.

Pull ARM SoC updates from Olof Johansson:
"A few SoC (code) changes have queued up this cycle, mostly for minor
changes and some refactoring and cleanup of legacy platforms. This
branch also contains a few of the fixes that weren't sent in by the
end of the release (all fairly minor).
- Adding an additional maintainer for the TEE subsystem (Sumit Garg)
- Quite a significant modernization of the IXP4xx platforms by Linus
Walleij, revisiting with a new PCI host driver/binding, removing
legacy mach/* include dependencies and moving platform
detection/config to drivers/soc. Also some updates/cleanup of
platform data.
- Core power domain support for Tegra platforms, and some
improvements in build test coverage by adding stubs for compile
test targets.
- A handful of updates to i.MX platforms, adding legacy (non-PSCI)
SMP support on i.MX7D, SoC ID setup for i.MX50, removal of platform
data and board fixups for iMX6/7.
... and a few smaller changes and fixes for Samsung, OMAP, Allwinner,
Rockchip"

This is a major chunk of IXP4xx modernization:
- Fist we move some registers around to make room for
the predetermined PCI I/O space.
- Then we add some Kconfig options to make it possible
to use the old PCI driver in parallell with the new
shiny one.
- Then we add the new PCI driver and some bindings for
it.
- On top of this we add an (ages old) patch from Arnd
that centralize the CPU/SoC detection in drivers/soc
and make the header a standard Linux header to avoid
the <mach/*> business in drivers.
- Then we split out and modernize some platform data
headers for pata, and hwrandom, and top it up with
DT bindings and support for hwrandom.

Generic drivers are unable to use the feature macros from mach/cpu.h
or the feature bits from mach/hardware.h, so move these into a global
header file along with some dummy helpers that list these features as
disabled elsewhere.

Add driver state syncing that is invoked once all PMC consumers are
attached and ready. The consumers are the power domain clients.
The synchronization callback is invoked once all client drivers are
probed, the driver core handles this for us. This callback informs
PMC driver that all voltage votes are initialized by each PD client
and it's safe to begin voltage scaling of the core power domain.
