The board file for Wolfson Cragganmore 6410 uses various KEY_* defines,
but does not include the relevant header directly and instead relies on
other headers to include it indirectly. With the upcoming cleanup of
matrix_keypad.h this indirection is now broken and we should include the
relevant header directly.

Here is the big set of USB and Thunderbolt driver changes for 6.1-rc1.
Nothing major in here, lots of little things with new devices supported
and updates for a few drivers. Highlights include:
- thunderbolt/USB4 devices supported a bit better than before,
and some new ids to enable new hardware devices
- USB gadget uvc updates for newer video formats and better v4l
integration (the v4l portions were acked by those maintainers)
- typec updates for tiny issues and more typec drivers for new
chips.
- xhci tiny updates for minor issues
- big usb-serial ftdi_sio driver update to handle new devices
better
- lots of tiny dwc3 fixes and updates for the IP block that is
showing up everywhere these days
- dts updates for new devices being supported
- other tiny janitorial and cleanups fixes for lots of different
USB drivers. Full details are in the shortlog.
All of these have been in linux-next for a while with no reported
issues.

There are a number of old Makefile.boot files that remain from the
multiplatform conversion, and three that are still in use.
These provide the "ZRELADDR", "PARAMS_PHYS" and "INITRD_PHYS" values
that are platform specific. It turns out that we can generally just
derive this from information that is available elsewhere:
- ZRELADDR is normally detected at runtime with the
CONFIG_AUTO_ZRELADDR flag, but also needed to be passed to
for 'make uImage'. In a multiplatform kernel, one always has
to pass this as the $(LOADADDR) variable, but in the StrongARM
kernels we can derive it from the sum of $(CONFIG_PHYS_OFFSET)
and $(TEXT_OFFSET) that are already known.
- PARAMS_PHYS and INITRD_PHYS are only used for bootpImage, which
in turn is only used for the pre-ATAGS 'param_struct' based boot
interface on StrongARM based machines with old boot loaders.
They can both be derived from CONFIG_PHYS_OFFSET and a machine
specific offset for the initrd, so all of the logic for these
can be part of arch/arm/boot/bootp/Makefile.

Over the past ten years, new machine support was based on device tree,
and an initial set of about 400 boards using ATAGS with boardfile
for booting were grandfathered in, with about half of them either
removed or converted to DT over time.
Based on the recent mailing list discussion I started, I have now
turned the findings into a set of patches that marks most board files as
'depends on UNUSED_BOARD_FILES', leaving only 38 of the 196 boards.
For the boards that are marked as unused, there are two final chances
for potential users: The removal is scheduled to take place after the
longterm stable kernel at the end of 2022, so users can stay on that
version for another few years, and if anyone still has one of these
machines and is planning to keep updating kernels beyond that version,
they can speak up now to have their boards taken off the list again.
Waiting for the LTS release also makes sure that there will be at
least one longterm kernel that contains the recent multiplatform
conversion along while still supporting all legacy boards.
The short summary of the current status is:
- The s3c24xx, cns3xxx, iop32x and mv78xx0 platforms have no known
users and will be removed entirely.
- The mmp and davinci platforms have DT support for the important
machines and will become DT-only after this.
- s3c64xx, dove, orion5x, and pxa keep some board files to allow
those to be migrated over to DT more easily, but most board files
are getting removed now. DT support on these platforms is partially
working but requires changes to additional drivers for the other
boards.
- omap1, ep93xx, sa1100, footbridge and rpc have no DT support at
the moment but have some boards with known users. Removing the board
files that nobody uses should make it easier to try a DT conversion
if anyone cares.
There is no explicit timeline what happens with the boards that remain
after this removal, but I expect to revisit this in the future, and
with most boards gone, there will be a good time to do a treewide
review of platform drivers that never gained DT support and have no
remaining in-tree board files.

Most of the s3c64xx board files appear to be unused, as the better

the Wolfson Cragganmore board, which remains in use as the reference
design for Wolfson/Cirrus devices. As the other boards get removed,

There are a total of eight platforms that only suppor ATAGS based boot
with board files but no devicetree booting.
For dove, the DT support is part of the mvebu platform, which shares
driver but no code in arch/arm.
Most of these will never get converted to DT, and the majority of the
board files appear to be entirely unused already. There are still known
users on a few machines, and there may be interest in converting some
omap1, ep93xx or footbridge machines over in the future.
For the moment, just add a Kconfig dependency to hide these platforms
completely when CONFIG_ATAGS is disabled, and reorder the priority
of the options: Rather than offering to turn ATAGS off for platforms
that have DT support, make it a top-level setting that determines
which platforms are visible.
The s3c24xx platform supports one machine with DT support, but it
cannot be built without also including ATAGS support, and the
entire platform is scheduled for removal, so leaving the entire
platform behind a dependency seems good enough.
All defconfig files should keep working, as the option remains default
enabled.

This series has been 12 years in the making, it mostly finishes the
work that was started with the founding of Linaro to clean up platform
support in the kernel.
The largest change here is a cleanup of the omap1 platform, which
is the final ARM machine type to get converted to the common-clk
subsystem. All the omap1 specific drivers are now made independent of the
mach/*.h headers to allow the platform to be part of a generic ARMv4/v5
multiplatform kernel. The last bit that enables this support is still
missing here while we wait for some last dependencies to make it into
the mainline kernel through other subsystems.
The s3c24xx, ixp4xx, iop32x, ep93xx and dove platforms were all almost
at the point of allowing multiplatform kernels, this work gets completed
here along with a few additional cleanup. At the same time, the s3c24xx
and s3c64xx are now deprecated and expected to get removed in the future.
The PXA and OMAP1 bits are in a separate branch because of dependencies.
Once both branches are merged, only the three Intel StrongARM platforms
(RiscPC, Footbridge/NetWinder and StrongARM1100) need separate kernels,
and there are no plans to include these.

The Samsung S3C24xx and S3C64xx platforms are very old designs. S3C2416
was introduced in 2008 and S3C6410 in 2009/2010. They are not widely
available anymore - out-of-stock on FriendlyArm (one of manufacturers of
boards) and only few specialist stores still offer them for quite a high
price.
The community around these platforms was not very active, so I suspect
no one really uses them anymore. Maintenance takes precious time so
there is little sense in keeping them alive if there are no real users.
Let's mark all S3C24xx and S3C64xx platforms as deprecated and mention
possible removal in after 2022 for the first and 2024 for the lattere.
The deprecation message will be as text in Kconfig, build message (not a
warning though) and runtime print error.
If there are any users, they might respond and postpone the removal.

Choosing big-endian vs little-endian kernels in Kconfig has not worked
correctly since the introduction of CONFIG_ARCH_MULTIPLATFORM a long
time ago.
The problems is that CONFIG_BIG_ENDIAN depends on
ARCH_SUPPORTS_BIG_ENDIAN, which can set by any one platform
in the config, but would actually have to be supported by all
of them.
This was mostly ok for ARMv6/ARMv7 builds, since these are BE8 and
tend to just work aside from problems in nonportable device drivers.
For ARMv4/v5 machines, CONFIG_BIG_ENDIAN and CONFIG_ARCH_MULTIPLATFORM
were never set together, so this was disabled on all those machines
except for IXP4xx.
As IXP4xx can now become part of ARCH_MULTIPLATFORM, it seems better to
formalize this logic: all ARMv4/v5 platforms get an explicit dependency
on being either big-endian (ixp4xx) or little-endian (the rest). We may
want to fix ixp4xx in the future to support both, but it does not work
in LE mode at the moment.
For the ARMv6/v7 platforms, there are two ways this could be handled
a) allow both modes only for platforms selecting
'ARCH_SUPPORTS_BIG_ENDIAN' today, but only LE mode for the
others, given that these were added intentionally at some
point.
b) allow both modes everwhere, given that it was already possible
to build that way by e.g. selecting ARCH_VIRT, and that the
list is not an accurate reflection of which platforms may or
may not work.
Out of these, I picked b) because it seemed slighly more logical
to me.

As a final bit of preparation for converting to ARCH_MULTIPLATFORM,
change the interrupt handling for s3c24xx to use sparse IRQs.
Since the number of possible interrupts is already fixed and relatively
small per chip, just make it use all legacy interrupts preallocated
using the .nr_irqs field in the machine descriptor, rather than actually
allocating domains on the fly.

BAST is the one machine that theoretically supports unmodified ISA
drivers for hardware on its PC/104 connector, using a custom version of
the inb()/outb() and inw()/outw() macros.
This is incompatible with the generic version used in asm/io.h, and
can't easily be used in a multiplatform kernel.
Removing the special case for 16-bit I/O port access on BAST gets us
closer to multiplatform, at the expense of any PC/104 users with 16-bit
cards having to either use an older kernel or modify their ISA drivers
to manually ioremap() the area and use readw()/write() in place of
inw()/outw(). Either way is probably ok, given that there is a
recurring discussion about dropping s3c24xx altogether, and many
traditional ISA drivers are already gone.
Machines other than BAST already have no support for ISA drivers, though a
couple of them do map one of the external chip-selects into the ISA port
range, using the same address for 8-bit and 16-bit I/O. It is unlikely
that anything actually uses this mapping, but it's also easy to keep
this working by mapping it to the normal platform-independent PCI I/O
base that is otherwise unused on s3c24xx.
The mach/map-base.h file is no longer referenced in global headers and
can be moved into the platform directory.

The only effect of this symbol is to select PWM_SAMSUNG. Drop it and fix
the affected defconfigs to still keep PWM_SAMSUNG=y. Developers using
MACH_NEO1973_GTA02 and/or MACH_RX1950 now have to manually select PWM and
PWM_SAMSUNG (and get the freedom to select is as a module or not at all).
A side effect of this change is that allmodconfig now contains
PWM_SAMSUNG=m (which was =y before).

__setup() handlers should return 1 to obsolete_checksetup() in
init/main.c to indicate that the boot option has been handled.
A return of 0 causes the boot option/value to be listed as an Unknown
kernel parameter and added to init's (limited) argument or environment
strings. Also, error return codes don't mean anything to
obsolete_checksetup() -- only non-zero (usually 1) or zero.
So return 1 from jive_mtdset().

A separate Kconfig option HAVE_S3C2410_I2C for Samsung SoCs is not
really needed and the i2c-s3c24xx driver can depend on Samsung ARM
architectures instead. This also enables i2c-s3c2410 for arm64 Exynos
SoCs, which is required for example by Exynos850.
This is basically continuation of work made in following commits:
- commit d96890fca9 ("rtc: s3c: remove HAVE_S3C_RTC in favor of
direct dependencies")
- commit 7dd3cae90d ("ARM: samsung: remove HAVE_S3C2410_WATCHDOG and

Now that entry code handles IRQ entry (including setting the IRQ regs)
before calling irqchip code, irqchip code can safely call
generic_handle_domain_irq(), and there's no functional reason for it to
call handle_domain_irq().
Let's cement this split of responsibility and remove handle_domain_irq()
entirely, updating irqchip drivers to call generic_handle_domain_irq().
For consistency, handle_domain_nmi() is similarly removed and replaced
with a generic_handle_domain_nmi() function which also does not perform
any entry logic.
Previously handle_domain_{irq,nmi}() had a WARN_ON() which would fire
when they were called in an inappropriate context. So that we can
identify similar issues going forward, similar WARN_ON_ONCE() logic is
added to the generic_handle_*() functions, and comments are updated for
clarity and consistency.

There are three noteworthy updates for 32-bit arm platforms this time:
- The Microchip SAMA7 family based on Cortex-A7 gets introduced, a new
cousin to the older SAM9 (ARM9xx based) and SAMA5 (Cortex-A5 based)
SoCs.
- The ixp4xx platform (based on Intel XScale) is finally converted to
device tree, and all the old board files are getting removed now.
- The Cirrus Logic EP93xx platform loses support for the old
MaverickCrunch FPU. Support for compiling user space applications
was already removed in gcc-4.9, and the kernel support for old
applications could not be built with clang ias. After confirming
that there are no remaining users, removing this from the kernel
seemed better than adding support for unused features to clang.

pwm_request() is deprecated because (among others) it depends on a global
numbering of PWM devices. So register a pwm_lookup to pick the right PWM
device (identified by provider and its local id) and use pwm_get().
Before this patch the PWM #1 was used. This is provided by the
samsung-pwm device which is the only PWM provider on this machine. The
local offset is 1, see also commit c107fe904a ("ARM: S3C24XX: Use PWM
lookup table for mach-rx1950") with a similar conversion for PWM #0.
As a follow up specify the period only once and symmetrically use pwm_put()
instead of pwm_free() to drop the reference.

SoC changes, a substantial part of this is cleanup of some of the older
platforms that used to have a bunch of board files. In particular:
- Removal of non-DT i.MX platforms that haven't seen activity in years,
it's time to remove them.
- A bunch of cleanup and removal of platform data for TI/OMAP platforms,
moving over to genpd for power/reset control (yay!)
- Major cleanup of Samsung S3C24xx and S3C64xx platforms, moving them
closer to multiplatform support (not quite there yet, but getting
close).
THere are a few other changes too, smaller fixlets, etc. For new
platform support, the primary ones re:
- New SoC: Hisilicon SD5203, ARM926EJ-S platform.
- Cpufreq support for i.MX7ULP

- Major cleanup of Samsung S3C24xx and S3C64xx platforms, moving them
closer to multiplatform support (not quite there yet, but getting
close).
There are a few other changes too, smaller fixlets, etc. For new
platform support, the primary ones are:
- New SoC: Hisilicon SD5203, ARM926EJ-S platform.
- Cpufreq support for i.MX7ULP"

PWM timer initialization has two independent implementations - one for
S3C24xx and one for S3C64xx. The naming however was always the same
and before also the declaration was shared. This is confusing, error
prone and might cause issues when trying to build multiplatform kernel.
