A few old machines have not been converted away from the old-style
gpiolib interfaces. Make these select the new CONFIG_GPIOLIB_LEGACY
symbol so the code still works where it is needed but can be left
out otherwise.

The crag6410 board is one of the last users of the gpio-led driver
with plain gpio numbers. The driver has several ways to pass this
information without using gpio numbers, using a lookup table is
the easiest way.

This converts the Arizona driver to use GPIO descriptors
exclusively, deletes the legacy code path an updates the
in-tree user of legacy GPIO.
The GPIO lines for mic detect polarity and headphone ID
detection are made exclusively descriptor-oriented. The
headphone ID detection could actually only be used by
the legacy GPIO code, but I converted it to use a
descriptor if someone would actually need it so we don't
just drop useful code.
The compatible "wlf,hpdet-id-gpio" is not in the device
tree bindings and only intended to be used by software
nodes if any. If someone insists I can try to add a
binding for it, but I doubt there is any real user so
it seems pointless.

Several drivers can benefit from registering per-instance data along
with the syscore operations. To achieve this, move the modifiable fields
out of the syscore_ops structure and into a separate struct syscore that
can be registered with the framework. Add a void * driver data field for
drivers to store contextual data that will be passed to the syscore ops.

The conversion of all GPIO drivers to using the .set_rv() and
.set_multiple_rv() callbacks from struct gpio_chip (which - unlike their
predecessors - return an integer and allow the controller drivers to
indicate failures to users) is now complete and the legacy ones have
been removed. Rename the new callbacks back to their original names in
one sweeping change.

The GPIO device in crag6410 is registered with struct bgpio_pdata passed
as platform_data to the gpio-mmio driver. We want to remove the
bgpio_pdata from the kernel and the gpio-mmio driver is now also able to
get the relevant values from the software node. Set up device properties
and switch to using platform_device_info to register the device as
platform_add_devices() doesn't allow us to pass device properties to the
driver model.

The wlf-gf-module driver doesn't use the driver_data member of struct
i2c_device_id, so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

Kbuild conventionally uses $(obj)/ for generated files, and $(src)/ for
checked-in source files. It is merely a convention without any functional
difference. In fact, $(obj) and $(src) are exactly the same, as defined
in scripts/Makefile.build:
src := $(obj)
When the kernel is built in a separate output directory, $(src) does
not accurately reflect the source directory location. While Kbuild
resolves this discrepancy by specifying VPATH=$(srctree) to search for
source files, it does not cover all cases. For example, when adding a
header search path for local headers, -I$(srctree)/$(src) is typically
passed to the compiler.
This introduces inconsistency between upstream and downstream Makefiles
because $(src) is used instead of $(srctree)/$(src) for the latter.
To address this inconsistency, this commit changes the semantics of
$(src) so that it always points to the directory in the source tree.
Going forward, the variables used in Makefiles will have the following
meanings:
$(obj) - directory in the object tree
$(src) - directory in the source tree (changed by this commit)
$(objtree) - the top of the kernel object tree
$(srctree) - the top of the kernel source tree
Consequently, $(srctree)/$(src) in upstream Makefiles need to be replaced
with $(src).

This converts the WM8996 codec to use GPIO descriptors, an a similar
way to WM5100.
The driver is instantiating a GPIO chip named wm8996, and we get
rid of the base address for the GPIO chip from the platform data and
just use dynamic numbering. Move base and ngpio into the static
gpio_chip template.
Fix up the only in-tree user which is the Cragganmore 6410 module.

This converts the WM5100 codec to use GPIO descriptors, a pretty
straight-forward conversion with the following peculiarities:
- The driver is instantiating a GPIO chip named wm5100, and the
headphone polarity detection GPIO is lifted from there. We add
this to the GPIO descriptor table as well, and we can then get
rid of also the base address for the GPIO chip from the
platform data and just use dynamic numbering.
- Fix up the only in-tree user which is the Cragganmore 6410
module.

This converts the WM1250-EV1 codec to use GPIO descriptors.
It turns out that the platform data was only used to pass some
global GPIO numbers from a board file, so we get rid of this
and also switch over the single in-tree user in the S3C
Cragganmore module for S3C 6410.
The driver obtains two GPIO lines named OSR and master and just
pull them low, we leave this behaviour as it was.

I added $(srctree)/ to some included Makefiles in the following commits:
- 3204a7fb98a3 ("kbuild: prefix $(srctree)/ to some included Makefiles")
- d82856395505 ("kbuild: do not require sub-make for separate output tree builds")
They were a preparation for removing --include-dir flag.
I have never thought --include-dir useful. Rather, it _is_ harmful.
For example, run the following commands:
$ make -s ARCH=x86 mrproper defconfig
$ make ARCH=arm O=foo dtbs
make[1]: Entering directory '/tmp/linux/foo'
HOSTCC scripts/basic/fixdep
Error: kernelrelease not valid - run 'make prepare' to update it
UPD include/config/kernel.release
make[1]: Leaving directory '/tmp/linux/foo'
The first command configures the source tree for x86. The next command
tries to build ARM device trees in the separate foo/ directory - this
must stop because the directory foo/ has not been configured yet.
However, due to --include-dir=$(abs_srctree), the top Makefile includes
the wrong include/config/auto.conf from the source tree and continues
building. Kbuild traverses the directory tree, but of course it does
not work correctly. The Error message is also pointless - 'make prepare'
does not help at all for fixing the issue.
This commit fixes more arch Makefile, and finally removes --include-dir
from the top Makefile.
There are more breakages under drivers/, but I do not volunteer to fix
them all. I just moved --include-dir to drivers/Makefile.
With this commit, the second command will stop with a sensible message.
$ make -s ARCH=x86 mrproper defconfig
$ make ARCH=arm O=foo dtbs
make[1]: Entering directory '/tmp/linux/foo'
SYNC include/config/auto.conf.cmd

similar symbols that are no longer available with the platform gone,
though the drivers themselves are still used on newer platforms,
so remove these hacks.

The platform was deprecated in commit 6a5e69c7ddea ("ARM: s3c: mark
as deprecated and schedule removal") and can be removed. This includes
all files that are exclusively for s3c24xx and not shared with s3c64xx,
as well as the glue logic in Kconfig and the maintainer file entries.

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.

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.

Pull ARM boardfile deprecation from Arnd Bergmann:
"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"

The s3c24xx platform is already scheduled for removal in early 2023,
with s3c64xx meeting the same fate a year later.
Most of the s3c64xx board files appear to be unused, as the better
maintained ones already got converted to DT. The main exception is
the Wolfson Cragganmore board, which remains in use as the reference
design for Wolfson/Cirrus devices. As the other boards get removed,
this one stays around along with the DT based machines.
The s3c6400_defconfig file now disables the unused boards, while the
s3c24xx defconfig files all turn on CONFIG_UNUSED_BOARD_FILES to
remain usable.

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.

Pull ARMv4T/v5 multiplatform support from Arnd Bergmann:
"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"
