cddaac0459 ARM: pxa/gumstix: fix attaching properties to vbus gpio device
Commit f1d6588af9 tried to convert GPIO lookup tables to software
properties for the vbus gpio device, bit forgot the most important
step: actually attaching the new properties to the device.

Also fix up the name of the property array to reflect the board name,
and add missing gpio/property.h and devices.h includes absence of which
causes compile failures on some configurations.

Switch "#ifdef CONFIG_USB_PXA25X" to "#if IS_ENABLED(CONFIG_USB_PXA25X)"
because it should not matter if the driver is buolt in or a module, it
still need vbus controls.

ARM: pxa: fix build breakage on PXA3xx
Commit 917195d6f8 ("ARM: pxa: consolidate GPIO chip platform data")
tried to reuse the same instance of platform data for PXA25x and PXA27x
GPIO controllers by moving it into arch/arm/mach-pxa/devices.c
Unfortunately this file is built for other PXA variants which resulted
in the following error:

>> arm-linux-gnueabi-ld: arch/arm/mach-pxa/devices.o:(.data+0x167c): undefined reference to `gpio_set_wake'

Fix this by using #ifdef around PXA25x and PXA27x GPIO controller device
structures and associated data.

- making a trampoline for the driver to support non-default number

daa22f5a78 Modules changes for v6.6-rc1
Summary of the changes worth highlighting from most interesting to boring below:
 
   * Christoph Hellwig's symbol_get() fix to Nvidia's efforts to circumvent the
     protection he put in place in year 2020 to prevent proprietary modules from
     using GPL only symbols, and also ensuring proprietary modules which export
     symbols grandfather their taint. That was done through year 2020 commit
     262e6ae708 ("modules: inherit TAINT_PROPRIETARY_MODULE"). Christoph's new
     fix is done by clarifing __symbol_get() was only ever intended to prevent
     module reference loops by Linux kernel modules and so making it only find
     symbols exported via EXPORT_SYMBOL_GPL(). The circumvention tactic used
     by Nvidia was to use symbol_get() to purposely swift through proprietary
     module symbols and completley bypass our traditional EXPORT_SYMBOL*()
     annotations and community agreed upon restrictions.
 
     A small set of preamble patches fix up a few symbols which just needed
     adjusting for this on two modules, the rtc ds1685 and the networking enetc
     module. Two other modules just needed some build fixing and removal of use
     of __symbol_get() as they can't ever be modular, as was done by Arnd on
     the ARM pxa module and Christoph did on the mmc au1xmmc driver.
 
     This is a good reminder to us that symbol_get() is just a hack to address
     things which should be fixed through Kconfig at build time as was done in
     the later patches, and so ultimately it should just go.
 
   * Extremely late minor fix for old module layout 055f23b74b ("module: check
     for exit sections in layout_sections() instead of module_init_section()") by
     James Morse for arm64. Note that this layout thing is old, it is *not*
     Song Liu's commit ac3b432839 ("module: replace module_layout with
     module_memory"). The issue however is very odd to run into and so there was
     no hurry to get this in fast.
 
   * Although the fix did not go through the modules tree I'd like to highlight
     the fix by Peter Zijlstra in commit 5409730962 ("x86/static_call: Fix
     __static_call_fixup()") now merged in your tree which came out of what
     was originally suspected to be a fallout of the the newer module layout
     changes by Song Liu commit ac3b432839 ("module: replace module_layout
     with module_memory") instead of module_init_section()"). Thanks to the report
     by Christian Bricart and the debugging by Song Liu & Peter that turned to
     be noted as a kernel regression in place since v5.19 through commit
     ee88d363d1 ("x86,static_call: Use alternative RET encoding").
 
     I highlight this to reflect and clarify that we haven't seen more fallout
     from ac3b432839 ("module: replace module_layout with module_memory").
 
   * RISC-V toolchain got mapping symbol support which prefix symbols with "$"
     to help with alignment considerations for disassembly. This is used to
     differentiate between incompatible instruction encodings when disassembling.
     RISC-V just matches what ARM/AARCH64 did for alignment considerations and
     Palmer Dabbelt extended is_mapping_symbol() to accept these symbols for

Pull modules updates from Luis Chamberlain:
 "Summary of the changes worth highlighting from most interesting to
  boring below:

   - Christoph Hellwig's symbol_get() fix to Nvidia's efforts to
     circumvent the protection he put in place in year 2020 to prevent
     proprietary modules from using GPL only symbols, and also ensuring
     proprietary modules which export symbols grandfather their taint.

     That was done through year 2020 commit 262e6ae708 ("modules:
     inherit TAINT_PROPRIETARY_MODULE"). Christoph's new fix is done by
     clarifing __symbol_get() was only ever intended to prevent module
     reference loops by Linux kernel modules and so making it only find
     symbols exported via EXPORT_SYMBOL_GPL(). The circumvention tactic
     used by Nvidia was to use symbol_get() to purposely swift through
     proprietary module symbols and completely bypass our traditional
     EXPORT_SYMBOL*() annotations and community agreed upon
     restrictions.

     A small set of preamble patches fix up a few symbols which just
     needed adjusting for this on two modules, the rtc ds1685 and the
     networking enetc module. Two other modules just needed some build
     fixing and removal of use of __symbol_get() as they can't ever be
     modular, as was done by Arnd on the ARM pxa module and Christoph
     did on the mmc au1xmmc driver.

     This is a good reminder to us that symbol_get() is just a hack to
     address things which should be fixed through Kconfig at build time
     as was done in the later patches, and so ultimately it should just
     go.

   - Extremely late minor fix for old module layout 055f23b74b
     ("module: check for exit sections in layout_sections() instead of
     module_init_section()") by James Morse for arm64. Note that this
     layout thing is old, it is *not* Song Liu's commit ac3b432839
     ("module: replace module_layout with module_memory"). The issue
     however is very odd to run into and so there was no hurry to get
     this in fast.

   - Although the fix did not go through the modules tree I'd like to
     highlight the fix by Peter Zijlstra in commit 5409730962
     ("x86/static_call: Fix __static_call_fixup()") now merged in your
     tree which came out of what was originally suspected to be a
     fallout of the the newer module layout changes by Song Liu commit
     ac3b432839 ("module: replace module_layout with module_memory")
     instead of module_init_section()"). Thanks to the report by
     Christian Bricart and the debugging by Song Liu & Peter that turned
     to be noted as a kernel regression in place since v5.19 through
     commit ee88d363d1 ("x86,static_call: Use alternative RET
     encoding").

     I highlight this to reflect and clarify that we haven't seen more
     fallout from ac3b432839 ("module: replace module_layout with
     module_memory").

   - RISC-V toolchain got mapping symbol support which prefix symbols
     with "$" to help with alignment considerations for disassembly.

     This is used to differentiate between incompatible instruction
     encodings when disassembling. RISC-V just matches what ARM/AARCH64
     did for alignment considerations and Palmer Dabbelt extended
     is_mapping_symbol() to accept these symbols for RISC-V. We already
     had support for this for all architectures but it also checked for
     the second character, the RISC-V check Dabbelt added was just for
     the "$". After a bit of testing and fallout on linux-next and based
     on feedback from Masahiro Yamada it was decided to simplify the
     check and treat the first char "$" as unique for all architectures,
     and so we no make is_mapping_symbol() for all archs if the symbol
     starts with "$".

     The most relevant commit for this for RISC-V on binutils was:

       https://sourceware.org/pipermail/binutils/2021-July/117350.html

   - A late fix by Andrea Righi (today) to make module zstd

     large compressed modules. I suspect we'll see similar things for
     other decompression algorithms soon.

The spitz board file uses the obscure symbol_get() function
to optionally call a function from sharpsl_pm.c if that is
built. However, the two files are always built together
these days, and have been for a long time, so this can
be changed to a normal function call.

5bb578a0c1 ARM: 9298/1: Drop custom mdesc->handle_irq()
ARM exclusively uses GENERIC_IRQ_MULTI_HANDLER, so at some point
set_handle_irq() needs to be called to handle system-wide
interrupts.

For all DT-enabled boards, this call happens down in the
drivers/irqchip subsystem, after locating the target irqchip
driver from the device tree.

We still have a few instances of the boardfiles with machine
descriptors passing a machine-specific .handle_irq() to the
ARM kernel core.

Get rid of this by letting the few remaining machines consistently
call set_handle_irq() from the end of the .init_irq() callback
instead and diet down one member from the machine descriptor.

a9ff696160 ARM: mm: Make virt_to_pfn() a static inline
Making virt_to_pfn() a static inline taking a strongly typed
(const void *) makes the contract of a passing a pointer of that
type to the function explicit and exposes any misuse of the
macro virt_to_pfn() acting polymorphic and accepting many types
such as (void *), (unitptr_t) or (unsigned long) as arguments
without warnings.

Doing this is a bit intrusive: virt_to_pfn() requires
PHYS_PFN_OFFSET and PAGE_SHIFT to be defined, and this is defined in
<asm/page.h>, so this must be included *before* <asm/memory.h>.

The use of macros were obscuring the unclear inclusion order here,
as the macros would eventually be resolved, but a static inline
like this cannot be compiled with unresolved macros.

The naive solution to include <asm/page.h> at the top of
<asm/memory.h> does not work, because <asm/memory.h> sometimes
includes <asm/page.h> at the end of itself, which would create a
confusing inclusion loop. So instead, take the approach to always
unconditionally include <asm/page.h> at the end of <asm/memory.h>

arch/arm uses <asm/memory.h> explicitly in a lot of places,
however it turns out that if we just unconditionally include
<asm/memory.h> into <asm/page.h> and switch all inclusions of
<asm/memory.h> to <asm/page.h> instead, we enforce the right
order and <asm/memory.h> will always have access to the
definitions.

Put an inclusion guard in place making it impossible to include
<asm/memory.h> explicitly.

The problem is that there is a declaration for each of these, but
it's only seen by the caller and not the callee. Moving these
into appropriate header files ensures that both use the same
calling conventions and it avoids the warnings.

767d83361a Input: ads7846 - Convert to use software nodes
The Nokia 770 is using GPIOs from the global numberspace on the
CBUS node to pass down to the LCD controller. This regresses when we
let the OMAP GPIO driver use dynamic GPIO base.

The Nokia 770 now has dynamic allocation of IRQ numbers, so this
needs to be fixed for it to work.

As this is the only user of LCD MIPID we can easily augment the
driver to use a GPIO descriptor instead and resolve the issue.

The platform data .shutdown() callback wasn't even used in the
code, but we encode a shutdown asserting RESET in the remove()
callback for completeness sake.

The CBUS also has the ADS7846 touchscreen attached.

Populate the devices on the Nokia 770 CBUS I2C using software
nodes instead of platform data quirks. This includes the LCD
and the ADS7846 touchscreen so the conversion just brings the LCD
along with it as software nodes is an all-or-nothing design
pattern.

The ADS7846 has some limited support for using GPIO descriptors,
let's convert it over completely to using device properties and then
fix all remaining boardfile users to provide all platform data using
software nodes.

Dump the of includes and of_match_ptr() in the ADS7846 driver as part
of the job.

Since we have to move ADS7846 over to obtaining the GPIOs it is
using exclusively from descriptors, we provide descriptor tables
for the two remaining in-kernel boardfiles using ADS7846:

- PXA Spitz
- MIPS Alchemy DB1000 development board

It was too hard for me to include software node conversion of
these two remaining users at this time: the spitz is using a
hscync callback in the platform data that would require further
GPIO descriptor conversion of the Spitz, and moving the hsync
callback down into the driver: it will just become too big of
a job, but it can be done separately.

The MIPS Alchemy DB1000 is simply something I cannot test, so take
the easier approach of just providing some GPIO descriptors in
this case as I don't want the patch to grow too intrusive.

As we see that several device trees have incorrect polarity flags
and just expect to bypass the gpiolib polarity handling, fix up
all device trees too, in a separate patch.

ARM: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

After commit b5aaaa666a ("ARM: pxa: add Kconfig dependencies for

for the board files that are considered unused.

As a side-effect of this, the PXA310 and PXA320 support is not built
into the kernel any more, even though it should work in principle as
long as the symbols are enabled. As Robert points out, there are dts
files for zylonite and cm-x300, though those have not made it into the
mainline kernel.

7d0d3fa733 ARM: boardfile deprecation for 6.0
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.

ARM: pxa2xx: Fix GPIO descriptor tables
Laurence reports:

"Kernel >5.18 on Zaurus has a bug where the power management code can't
talk to devices, emitting the following errors:

sharpsl-pm sharpsl-pm: Error: AC check failed: voltage -22.
sharpsl-pm sharpsl-pm: Charging Error!
sharpsl-pm sharpsl-pm: Warning: Cannot read main battery!

Looking at the recent changes, I found that commit 31455bbda2 ("spi:
pxa2xx_spi: Convert to use GPIO descriptors") replaced the deprecated
SPI chip select platform device code with a gpiod lookup table. However,
this didn't seem to work until I changed the `dev_id` member from the
device name to the bus id. I'm not entirely sure why this is necessary,
but I suspect it is related to the fact that in sysfs SPI devices are
attached under /sys/devices/.../dev_name/spi_master/spiB/spiB.C, rather
than directly to the device."

After reviewing the change I conclude that the same fix is needed
for all affected boards.

b5aaaa666a ARM: pxa: add Kconfig dependencies for ATAGS based boards
Most of the traditional board files are no longer used by anyone and
will be removed next year, while the DT based machine support remains.

Adding a CONFIG_ATAGS dependency around all the board files means
that they now actaully get disabled when ATAGS support is left out,
and the individual boards that have no known users are marked
as depending on CONFIG_UNUSED_BOARD_FILES, with the plan to remove
them in early 2023 unless someone else shows interest.

Laurence de Bruxelles intends to work on converting the Spitz/Akita/Borzoi
family of Sharp Zaurus SL machines to DT, to make that easier those
remain for the moment.

In addition, the "Gumstix" machine is the one that is supported in
qemu with 256MB of RAM, which makes it particularly nice for testing,
I'm leaving it in hoping that someone can take care of converting it to
DT as well.

Finally, Marc Zyngier is still able to test the Zeus and Viper machines,
so these could be saved as well if anyone wants to conver them to DT.
This seems less likely, so I'm marking them as unused for the time being.

For the defconfig files, both the pxa3xx_defconfig and pxa_defconfig
now only enable the boards that are not marked as unused, while all the
other ones explicitly enable CONFIG_UNUSED_BOARD_FILES to still allow
building the kernels.
