OpenBMC Linux v6.12

[Joel Stanley]

Here's the new kernel tree, based on the upstream LTS v6.12 release.

  https://gerrit.openbmc.org/c/openbmc/openbmc/+/77224

Please test your machines and +1 the patch. Note that two of the
machines didn't pass CI as the kernel is too big for the image.

The tree contains most of the patches that were in 6.6. A large amount
of code has been merged upstream, which is great. Congratulations if
you landed a patch over the past year, it makes for an easier to
maintain openbmc tree, and means you get security backports for free.

Notably these patches didn't make it in the rebase:

pmbus (core): One-shot retries for failure to set page
pmbus (max31785): Wrap all I2C accessors in one-shot failure handlers

-> now uses pmbus_wait, which is the upstream solution to slow to
respond i2c devices

i2c: core: Add mux root adapter operations
iio: si7020: Lock root adapter to wait for reset

-> Eddie, please resubmit if still required as the core patch does not
apply. Ideally speak with upstream about a long term solution.

eeprom: ee1004: Enable devices on multiple busses
dt-bindings: trivial-devices: Add Atmel
AT30TSE004A serial eeprom

-> Eddie, please resubmit if still required, as it does not apply cleanly

leds: pca955x: Add HW blink support
 -> Eddie, please resend upstream now that the led maintainer seems to
be active again. You don't need to resend as the patches are in
dev-6.12.

ARM: aspeed_g5_defconfig: Enable G6 sensors, PWM and regulators
 -> Andrew to send upstream

Eddie and Ninad, the various IBM systems that used XDMA went upstream.
The revert that Andrew sent to keep the nodes in place is still in the
tree, some machines might still be missing them. Please submit your
downstream patches while you work on a long term solution there.

The gerrit commit message for the bump follows:

There are 92 patches in the tree, with 30 of those patches not yet
queued for merging in mainline.

v6.12 is an LTS kernel as decreed by the kernel.org maintainers. The
OpenBMC kernel maintainers encourage everyone to ship the latest
kernel as it has the most code review and upstream code.
