c8e93255f6 omap3: evm: Drop old musb omap3 driver
The USB_OMAP3 driver was (re)added in commit e74e9f620a as part
of migrating to DM_USB but the config already had MUSB_OMAP2PLUS
which is the newer musb driver and what other omap3 devices use.
So drop it so we can drop the old driver.

96edadab54 Merge patch series "ti: add speed grades support for AM62a"
Anshul Dalal <anshuld@ti.com> says:

TI offers SoCs in various speed grades, each speed grade specifies a
certain maximum operating frequency of the clocks for each core.

In K3's boot flow, the R5 SPL starts the A53 or A72 core and configures
the correct clocks and power using the K3 ARM64 rproc driver
(compatible: ti,am654-rproc). However, the driver expects the dt node
for the ARM64 core to be set with a correct "assigned-clock-rates"
value.

Currently the dt has a value of 1.2GHz for the A53 core on AM62a, this
is incorrect for lower speed grades. Therefore this patch set adds
support for fixing this value at runtime based on the detected speed
grade from the efuse MMR.

For the speed grade table, refer to Table 6-1 of the AM62a datasheet.

65a6b83a9b mach-k3: refactor A53 speed grade clock-rate fixup
The K3 ARM64 rproc driver uses the "assigned-clock-rates" value in the
respective "/a53@0" node to properly configure the clocks for the A53
core.

Although the clock value in the DT node might need to be fixed based on
SoC's speed grade at runtime. Certain SoCs such as AM62p and AM62x
already had this implemented, this patch moves the common code to
common.c to avoid duplication and simplify speed grade handling.

The logic to detect the correct entry in the "assigned-clock-rates"
property has also changed. Where we earlier relied on per SoC specific
device and clock IDs for the A53 core, we now use the "clock-names"
property which is device agnostic.

b526ec6f3c pinctrl: exynos: bind GPIO driver along with pinctrl
The devicetree of Samsung devices typically have the pin controller and
GPIO bank descriptors under the same pinctrl node. In U-Boot, these are
handled by two separate drivers. It is not possible to invoke both
drivers from a single node compatible.

Bind the GPIO driver on pinctrl driver bind, with the same OF node as
the pinctrl driver. This solution is already being used in other pinctrl
drivers. The hierarchy, as represented in `dm tree`, is as follows:

  pinctrl@13750000
  |-- gpio-banks
  |   |-- gpr0-gpio-bank
  |   |-- gpr1-gpio-bank
  |   |-- gpr2-gpio-bank
  |   |-- gpr3-gpio-bank
  |   `-- gpr4-gpio-bank
  |-- sd0-bus-width1-pins
  |-- sd0-bus-width4-pins
  |-- sd0-bus-width8-pins
  `-- sd0-clk-pins

Since a bind function doesn't exist, create and add it to all pinctrl
drivers.

10fec1b7a3 Merge patch series "reenable dm_gpio tests, add support for gpio-line-names lookup"
Rasmus Villemoes <ravi@prevas.dk> says:

Hopefully third time's the charm.

I merely wanted to add support (mostly for use by the 'gpio' shell
command) for looking up a gpio via the gpio-line-names DT property. We
already have a "gpio_request_by_line_name()", but cmd/gpio.c does a
separate "lookup + request", so it felt more natural to teach the
lookup machinery this as well. That ran into
OF_CONTROL-but-not-OF_LIBFDT being a thing for SPL, so here's yet
another attempt.

Now, when trying to do my civic duty and add tests for this, I found
that test/dm/gpio.c has been defunct for a couple of years, and
reinstating it is not entirely trivial.

After a couple of rounds CI is now happy with this:

c92c3768b6 gpio: search gpio-line-names property in dm_gpio_lookup_name
In scripts as well as interactively, it's much nicer to be able to
refer to GPIOs via their names defined in the device tree property
"gpio-line-names", instead of the rather opaque names derived from the
bank name with a _xx suffix. E.g.

  gpio read factory_reset FACTORY_RESET
  if test $factory_reset = 1 ; then ...

versus

  gpio read factory_reset gpio@481ac000_16
  if test $factory_reset = 1 ; then ...

This is also consistent with the move on the linux/userspace side towards
using line names instead of legacy chip+offset or the even more legacy
global gpio numbering in sysfs.

As dev_read_stringlist_search() depends on both OF_CONTROL and
OF_LIBFDT (which matters for the SPL case), we need some .config
conditional. However, it only adds about ~50 bytes of code to U-Boot
proper, and dm_gpio_lookup_name() most often ends up being GC'ed for
SPL, thus adds no overhead there, so for now make it a hidden symbol
which is merely a convenient shorthand for
CONFIG_IS_ENABLED(OF_CONTROL) && CONFIG_IS_ENABLED(OF_LIBFDT).

23908d8f24 test: gpio: include in build, and fixup bitrot
Commit ebaa3d053e ("test: fix CONFIG_ACPIGEN dependencies"), which
got into v2022.10-rc1, accidentally left out a $
before (CONFIG_DM_GPIO), with the effect that test/dm/gpio.c has not
been built for three years.

Unsurprisingly, the code in there has bit-rotted.

- There's a missing ; causing plain build fail.

  That code was added in 9bf87e256c ("test: dm: update test for
  open-drain/open-source emulation in gpio-uclass"), which was part of
  v2020.07-rc3, i.e. long before the commit causing gpio.c to not be
  built at all. It did build at that time, but also, the missing
  semicolon wasn't found when fa847bb409 ("test: Wrap assert macros
  in ({ ... }) and fix missing semicolons") happened in 2023.

- Commit 592b6f394a ("led: add function naming option from linux")
  bumped sandbox,gpio-count for bank gpio_a in test.dts to 25, but
  didn't update the expected global gpio numbers accordingly.

- The "lookup by label" test likely worked when it was added, but then I
  inadvertently broke it when I noticed that dm_gpio_lookup_label()
  seemed to be broken in commit 10e66449d7 ("gpio-uclass: fix gpio
  lookup by label") - which landed in v2023.01-rc1, so after gpio.c
  was no longer being built.

  The "label" (which is a u-boot concept) that a "hogged gpio" gets is
  <gpio hog node name>.gpio-hog, which is why it used to work with the
  strncmp() but doesn't with strcmp().

  We can either revert 10e66449d7 or append the ".gpio-hog" suffix as
  done below. I don't really have a dog in that race; when I did
  10e66449d7, it was because I thought the "lookup by label" was
  actually about the standardized gpio-line-names property, but then I
  learnt it was not, so is not at all useful to me.

- The leak check now fails.

  Test: gpio_leak: gpio.c
  test/dm/core.c:112, dm_leak_check_end(): uts->start.uordblks == end.uordblks: Expected 0x2a95b0 (2790832), got 0x2a9650 (2790992)
  test/dm/gpio.c:328, dm_test_gpio_leak(): 0 == dm_leak_check_end(uts): Expected 0x0 (0), got 0x1 (1)
  Test: gpio_leak: gpio.c (flat tree)
  test/dm/core.c:112, dm_leak_check_end(): uts->start.uordblks == end.uordblks: Expected 0x2a9650 (2790992), got 0x2a9700 (2791168)
  test/dm/gpio.c:328, dm_test_gpio_leak(): 0 == dm_leak_check_end(uts): Expected 0x0 (0), got 0x1 (1)

  And it fails with the same differences (160/176) even if I
  remove the three lines that actually exercise any of the gpio code,
  i.e. make the whole function amount to

    ut_assertok(dm_leak_check_end(uts));

  Test: gpio_leak: gpio.c
  test/dm/core.c:112, dm_leak_check_end(): uts->start.uordblks == end.uordblks: Expected 0x2a95b0 (2790832), got 0x2a9650 (2790992)
  test/dm/gpio.c:325, dm_test_gpio_leak(): 0 == dm_leak_check_end(uts): Expected 0x0 (0), got 0x1 (1)
  Test: gpio_leak: gpio.c (flat tree)
  test/dm/core.c:112, dm_leak_check_end(): uts->start.uordblks == end.uordblks: Expected 0x2a9650 (2790992), got 0x2a9700 (2791168)
  test/dm/gpio.c:325, dm_test_gpio_leak(): 0 == dm_leak_check_end(uts): Expected 0x0 (0), got 0x1 (1)

  So I suspect that the leak is somewhere in the test framework
  setup/teardown code - dm_leack_check_end() isn't really used
  anywhere else except in a dm/core test. Bisecting to figure out
  where that was introduced is somewhat of a hassle because of the
  other bitrot, and because of the SWIG failure that makes it very
  hard to build older U-Boots.

  So since it's better to have most of the gpio tests actually
  working instead of leaving all of gpio.c as dead code, #if 0 that
  part out and leave it as an archeological exercise.

62e89de769 Merge patch series "rsa: fix dependency, rename and relocate RSASSA PSS symbols"
Quentin Schulz <foss+uboot@0leil.net> says:

While historically signature verification is mostly done for FIT such
FIT_SIGNATURE dependency for signature algorithm makes sense, it isn't
the only kind of file we can verify signatures of. It can also be done
manually with rsa_verify_hash() with an embedded public key.

Considering the impacted code is guarded by RSA_VERIFY, let's make the
symbol depend on that otherwise selecting it without RSA_VERIFY won't do
anything. The FIT_SIGNATURE dependency wasn't also enough before as it
only implied RSA_VERIFY.

Then, simply relocate the RSA SSA PSS padding with the other RSA symbols
in lib/rsa instead of in boot/ and rename it to remove the mention to
FIT.

Finally, add the PSS padding wherever PKCS1.5 padding is specified as
one or the other can be used.

63686bf6e0 boot: fix incorrect dependency of FIT_RSASSA_PSS
This padding has nothing to do with FIT except that we can make use of
it when verifying the FIT signatures.

This padding can also be used to verify the signature "manually" e.g. by
calling rsa_verify_hash() directly with an embedded public key.

Additionally, this padding is only useful if RSA (and specifically
RSA_VERIFY) is enabled otherwise it's not used.
The only other place it's used is in rsa-sign.c which is only built for
the host tools and handled by TOOLS_FIT_RSASSA_PSS symbol instead, so no
need to care for that one.

Finally, the FIT_SIGNATURE dependency also wasn't enough because it only
implies RSA_VERIFY, meaning it can be disabled and still have
FIT_RSASSA_PSS enabled.

So add a dependency on RSA_VERIFY and reword the input prompt.

9420160a0d CI: Move to Ubuntu 24.04 'Noble' as the base
The changes here are that we need to ensure python setuptools are
in our build virtual environments as they will no longer come in via
python even in a virtual environment. As part of this ensure setuptools
is in our cache and also include pytest-azurepipelines as we should have
been doing. Next, we move away from using apt-key directly and move that
stanza towards the rest of the apt work.  This also lets us drop
directly installing gnupg2. These steps are not strictly required for
24.04 but will be for later releases and are valid now. Finally, we drop
the unused PTYHONPATH ENV line.

In order to use these containers however, we need to stop running the
event_dump test as the 'addr2line' tool provided by binutils no longer
is able to decode those specific events in most cases. As this is a
problem with binutils and present for some time now, disabling the test
until someone has time to work with upstream this seems reasonable.

6d04828b45 dm: Remove pre-schema tag support
Support for using "u-boot,dm-..." rather than "bootph-..." has been
deprecated since February 2023. Any platforms using this have had a
console message saying to migrate by 2023.07. Go and remove all support
here now, for the v2026.01 release.

The results of this change that aren't clear from the above are that we
still have a checkpatch.pl error message, and document in
doc/develop/spl.rst that they have been migrated since 2023. We also
change the key2dtsi.py tool to use the correct bootph phase rather than
the legacy phase.

3547e315c1 clk: scmi: Defer issue of SCMI_CLOCK_ATTRIBUTES
Instead of resolving clock control flags using SCMI_CLOCK_ATTRIBUTES
during probe for each and every clock, resolve the clock control
flags using SCMI_CLOCK_ATTRIBUTES when the clock control flags are
first used. Because most clock are never used by U-Boot, this allows
reducing the amount of SCMI_CLOCK_ATTRIBUTES considerably, and this
improve probe time of the scmi clock driver and U-Boot start up time.

On Renesas X5H, with 1700+ SCMI clock, the boot time improved by 1.7s .

fdb1bffe28 clk: scmi: Postpone clock name resolution
The clock names are retrived via SCMI_CLOCK_ATTRIBUTES, called for each
clock ID. This may take a lot of time to complete and is not strictly
necessary. Register each clock as "scmi-%zu" instead, and let the first
call of SCMI_CLOCK_ATTRIBUTES fill in the actual clock name.

This has a side effect, which can be considered both an upside and also
a downside. Unused clock are never renamed and retain their placeholder
"scmi-%zu" name, which avoids empty clock names for nameless SCMI clock,
and avoids the name resolution and improves boot time. But for those
SCMI clock which do have name, that name is not listed until the clock
are used.

This is a preparatory patch for deferred issue of SCMI_CLOCK_ATTRIBUTES.

ef52f697f2 clk: scmi: Bulk allocate all sub-driver instance data
Allocate all sub-driver instance data at once. The amount of data that
have to be allocated is known up front, so is the size of the data, so
there is no need to call malloc() in a loop, mallocate all data at once.

The upside is, less heap fragmentation and fewer malloc() calls overall,
and a faster boot time.

The downside is, if some of the clock fail to register, then the clock
driver cannot free parts of the bulk allocated sub-driver instance data.
Such a failure can only occur if clk_register() were to fail, and if that
happens, the system has more significant problems. Worse, if a core clock
driver fails to probe, the system has even bigger problem.

0619cb3203 firmware: scmi: Add clock v3.2 CONFIG_SET support
SCMI v3.2 introduces a new clock CONFIG_SET message format that can
optionally carry also OEM specific configuration values beside the usual
clock enable/disable requests. Add support to use such new format when
talking to a v3.2 compliant SCMI platform.

Support existing enable/disable operations across different clock protocol
versions: this patch still does not add protocol operations to support the
new OEM specific optional configuration capabilities.

No functional change for the SCMI drivers users of the related enable and
disable clock operations.

[Marek: Remodel after Linux e49e314a2cf7 ("firmware: arm_scmi: Add clock v3.2 CONFIG_SET support")
        Support both old < 2.1 and new >= 2.1 protocol versions.

a5a0134570 firmware: scmi: Drop mmu_set_region_dcache_behaviour() misuse
MMU region cache behavior configuration for SCMI/SMT mailboxes is
platform specific. Even on ARM systems, the mailbox memory may not
even be located in any cacheable MMU region and may instead reside
in some SRAM. Remove this non-generic cache behavior configuration
code from generic code path.

It is unlikely that any platform is affected by this change if it
did configure its MMU regions correctly on start up. Platforms
which might be affected are i.MX94/95 and STM32MP.
