The RZ/G2L multi-function timer pulse unit 3 (MTU3a) is embedded in
the Renesas RZ/G2L family SoCs. It consists of eight 16-bit timer
channels and one 32-bit timer channel. It supports the following
functions
- Counter
- Timer
- PWM
The 8/16/32 bit registers are mixed in each channel.
Add MTU3a core driver for RZ/G2L SoC. The core driver shares the
clk and channel register access for the other child devices like
Counter, PWM and Clock event.

Since commit 0166dc11be ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.
It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.
As a minor optimization, this also lets us drop of_match_ptr(), as we
now know what it will resolve to, we might as well save cpp some work.

Instead of open coding p2sb_bar() functionality we are going to
use generic library. There is one more user en route.
This is more than just a clean-up. It also fixes a potential issue
seen when SPI BAR is 64-bit. The current code works if and only if
the PCI BAR of the hidden device is inside 4G address space. In case
when firmware decides to go above 4G, we will get a wrong address.

Intel Platform Monitoring Technology (PMT) support is indicated by presence
of an Intel defined PCIe Designated Vendor Specific Extended Capabilities
(DVSEC) structure with a PMT specific ID. The current MFD implementation
creates child devices for each PMT feature, currently telemetry, watcher,
and crashlog. However DVSEC structures may also be used by Intel to
indicate support for other features. The Out Of Band Management Services
Module (OOBMSM) uses DVSEC to enumerate several features, including PMT.
In order to support them it is necessary to modify the intel_pmt driver to
handle the creation of the child devices more generically. To that end,
modify the driver to create child devices for any VSEC/DVSEC features on
supported devices (indicated by PCI ID). Additionally, move the
implementation from MFD to the Auxiliary bus. VSEC/DVSEC features are
really multifunctional PCI devices, not platform devices as MFD was
designed for. Auxiliary bus gives more flexibility by allowing the
definition of custom structures that can be shared between associated
auxiliary devices and the parent device. Also, rename the driver from
intel_pmt to intel_vsec to better reflect the purpose.
This series also removes the current runtime pm support which was not
complete to begin with. None of the current devices require runtime pm.
However the support will be replaced when a device is added that requires
it.

The Samsung PMIC drivers since long time are used only on devicetree
platforms (Samsung Exynos) and there are no users with board files.
Drop the support for board files entirely and depend on OF for matching.

Qualcomm Technologies, Inc. PM8008 is a dedicated camera PMIC that
integrates all the necessary power management, housekeeping, and
interface support functions into a single IC. Its key features include
overtemperature protection, low-dropout linear regulators, GPIOs, and an
I2C interface.
Add an MFD driver to support it.

There is no reason why the arizona core,irq and codec model specific
regmap bits cannot be build as a module. All they do is export symbols
which are used by the arizona-spi/i2c and arizona-codec modules, which
themselves can be built as module.
Change the Kconfig and Makefile arizona bits so that the arizona MFD-core
can be built as a module.
This is especially useful on x86 platforms with a WM5102 codec, this
allows the arizona MFD driver necessary for the WM5102 codec to be
enabled in generic distro-kernels without growing the base kernel-image
size.
Note this also adds an explicit "depends on MFD_ARIZONA" to all the
arizona codec Kconfig options. The codec drivers use functions from mfd
arizona-core. These new depends are necessary to disallow the codec
drivers being builtin when the arizona-core is build as a module,
otherwise we end up with missing symbol errors when building vmlinuz.
