Merge tag 'soc-arm-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

2026-08-19T02:50:40+00:00

Pull ARM SoC platform updates from Arnd Bergmann:
 "The 32-bit Arm platforms are a bit more interesting this time: I
  refreshed an earlier series to mark code as deprecated that does have
  the tendency of getting in the way of cleanups and new features but
  has close to zero users. Among these are:

   - 22 of the remaining 28 legacy board files that predate the current
     devicetree based descriptions, using old chips from Intel and
     Marvell. The remaining six board files are for TI OMAP1 and Samsung
     s3c64xx chips and all still have known users.

   - support for Cortex-M3/M4/M7 and ARM1136r0 CPU cores and the 25
     machines based on these. These all use devicetree but the CPU
     support causes disproportional work. Most of them are just
     reference boards, the notable exceptions being the Nokia N800/N810
     tablet and the Buglabs BUG platform.

   - be8, be32, oabi and iwmmxt userspace binaries, which were mostly
     associated with the platforms now scheduled for removal and are
     increasingly problematic to support with modern toolchains.

  Nothing is actually removed at this point, to ensure that any
  remaining users continue to have the 7.3-LTS for a while longer.
  Patches for removal are currently being tested.

  Other updates include a continued work to convert GPIO number based
  interfaces to descriptors, a patch to restore little-endian mode on
  the one Arm platform (ixp4xx) that only worked in big-endian mode
  recently, and some minor cleanups and bugfixes"

ARM: Don't let ARMv5 platforms select USE_OF

2026-07-10T12:44:26+00:00

USE_OF is already selected by ARM (unless ARCH_FOOTBRIDGE || ARCH_RPC ||
ARCH_SA1100; these all conflict with ARCH_MULTI_V5). So there is no need
for an explicit select and it can be dropped.

ARM: PXA: mark remaining board files as deprecated

2026-07-03T18:36:07+00:00

In the 2021 board file removal, the gumstix and sharpsl
support was left around in order to make it easier to convert
more of the PXA platform to device tree, given that both
platforms had some level of support in qemu.

As far as I can tell, nobody has worked on additional DT
conversion in that time, and qemu has in turn deprecated
the entire PXA platform.

Schedule the remaining board files for removal now, as they
are unlikely to be of any help in the future. If anyone
wants to revive support for these machines, they can
obviously still contribute device tree based code and
work on updating the corresponding drivers.

Any drivers that are only usable on legacy PXA board files
can also get removed along with the boards, or saved by
adding devicetree support.

ARM: select legacy gpiolib interfaces where used

2026-05-07T12:16:41+00:00

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.

ARM: pxa: remove pxa93x support

2023-01-20T10:23:56+00:00

There is currently no devicetree support for pxa930 or pxa935
SoCs, and no board files remain. As it seems unlikely that anyone
is going to add DT support soon, let's drop the SoC specific code
now.

ARM: pxa: remove unused board files

2023-01-20T10:23:44+00:00

The majority of all pxa board files has not been touched in a long time,
and no users have spoken up in favor of keeping them around. This leaves
only support for the platforms that were already converted to DT, as
well as the gumstix and spitz/akita/borzoi machines that work in qemu
and can still be converted to DT later.

ARM: pxa: enable PXA310/PXA320 for DT-only build

2023-01-09T16:00:13+00:00

After commit b5aaaa666a85 ("ARM: pxa: add Kconfig dependencies for
ATAGS based boards"), the default PXA build no longer includes support
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.

ARM: pxa: add Kconfig dependencies for ATAGS based boards

2022-07-22T11:11:21+00:00

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.

Pull more ARM multiplatform updates from Arnd Bergmann:
 "The second part of the multiplatform changes now converts the
  Intel/Marvell PXA platform along with the rest. The patches went
  through several rebases before the merge window as bugs were found, so
  they remained separate.

  This has to touch a lot of drivers, in particular the touchscreen,
  pcmcia, sound and clk bits, to detach the driver files from the
  platform and board specific header files"
