Merge patch series "drivers: Driver support for ADI SC5xx SoCs"

Greg Malysa <malysagreg@gmail.com> says:

This series adds all of the supported peripheral drivers for the sc5xx
series of SoCs from Analog Devices and other drivers that are used by
the evaluation kits, such as a GPIO expander used by the EZLITE carrier
boards. This series passes gitlab CI tests.

Merge patch series "pci_auto: Downgrade prefetch if necessary"

This series from Patrick Rudolph <patrick.rudolph@9elements.com> fixes
an issue with how we treat PCIe vs PCI in some cases and fixes the
qemu-arm-sbsa reference platform support.

Link: https://lore.kernel.org/r/20250226135647.194842-1-patrick.rudolph@9elements.com

emulation: qemu-sbsa: Enable PCI enumeration

Enable PCI enumeration by default to get the Bochs display driver up
and running before the boot medium is scanned.
This is just to enhance the user-experience while booting the machine.

TEST: U-Boot logo, version, log output and the U-Boot shell is visible
      on the display device.

emulation: qemu-sbsa: Select SYS_PCI_64BIT

qemu's sbsa-ref is always using a 64bit CPU and the PCI prefetch MMIO
window is located above 4GiB, thus always enable SYS_PCI_64BIT.

pci_auto: Downgrade prefetch if necessary

Legacy PCI devices, like qemu's Bochs VGA device, are allowed to have
prefetchable 32-bit BARs, while PCIe devices are not allowed to have
32-bit prefetchable BARs. Typically prefetchable BARs are 64-bit and
typically the prefetch MMIO window is also 64-bit and placed above
4GiB, as it's the case on qemu sbsa-ref.

Currently the U-Boot code assumes that prefetchable BARs are
64-bit BARs and always tries to assign them into the prefetch
MMIO window.

When a 32-bit BAR is marked as prefetch, but the prefetch area is
not within the first 4GiB of the address space, then downgrade the
BAR and place it in the non-prefetch MMIO window.

For prefetch BARs there's no downside on being placed in non prefetch
MMIO areas, besides the possible slower performance when a driver tries
to map it Write-Combine.

TEST: Fixes pci_auto on QEMU sbsa-ref fails to autoconfigure BAR0.

common: edid: update timing selection logic

Older EDID timing algorithms relied solely on detailed timings, typically
optimized for a display's native resolution. This caused issues with newer
4K panels on older hardware, which couldn't handle those high resolutions.
To address this, the algorithm now also considers standard timings, offering

text along the lines of "[function] shall mark for update the last data
modification and last file status change timestamps of the parent
directory of each file." [1][2][3] The common theme is these timestamp
updates occur when a directory entry is added or removed. The
create_link() and delete_dentry_link() functions have been changed to
update the modification timestamp on the directory where the direntry
change occurs. This differs slightly from Linux in the case of rename(),
where Linux will not update `new_path`'s parent directory's timestamp if
it is replacing an existing file. (via `vfat_add_entry` [4])

The timestamps are not updated if the build configuration does not support
RTCs. This is an effort to minimize introducing erratic timestamps where
they would go from [current date] -> 2000-01-01 (error timestamp in the
FAT driver). I would assume an unchanged timestamp would be more valuable
than a default timestamp in these cases.

fs: fat: add rename

The implementation roughly follows the POSIX specification for
rename() [1]. The ordering of operations attempting to minimize the chance
for data loss in unexpected circumstances.

The 'mv' command was implemented as a front end for the rename operation
as that is what most users are likely familiar with in terms of behavior.

The 'FAT_RENAME' Kconfig option was added to prevent code size increase on
size-oriented builds like SPL.

fs: add rename infrastructure

The selection for *rename as the name for the rename/move operation
derives from the POSIX specification where they name the function
rename/renameat. [1] This aligns with Linux where the syscalls for
renaming/moving also use the rename/renameat naming.

fs: fat: factor out dentry link create/delete

The create_link() code was previously duplicated in two existing functions.
The two functions will be used in a future commit to achieve renaming.

scripts/checkpatch.pl: Upgrade IS_ENABLED_CONFIG to error for U-Boot

A problem we have today is that some instances of IS_ENABLED(FOO) have
crept in to the code. This is in turn because with checkpatch.pl this is
only a warning and not an error, so they were overlooked. And looking
deeper, in the Linux kernel this pattern is allowed because
IS_ENABLED(DEFINED_FLAG) is allowed if discouraged and a quick skim of
the instances I saw in the current kernel follow this pattern. In U-Boot
however, this is not allowed, so bump to an error.

fs/squashfs: Fix memory leak in sqfs_size_nest()

In case MAX_SYMLINK_NEST is reached while determining the size
on a symlink node, the function returns immediately.
This would not free the resources after the free_strings: label
causing a memory leak.

Set the ret value and just break out of the switch to fix this.

mcheck: Fix SPDX License Identifier to LGPL-2.1-or-later

The GPL-2.1+ SPDX License Identifier doesn't exist, but luckily the full
license text was available which shows that GPL-2.1+ was a typo and it
should have been LGPL-2.1-or-later.
As the '+' in LGPL-2.1+ is deprecated in SPDX 3.0, use the preferred
identifier, which is '-or-later'.

Normally the full license header is removed when switching to SPDX
License Identifiers, so do that now.
