During clock's registration, clock's name are used to establish parent -
child relation. On STM32MP13 and STM32MP25, most of SCMI clocks are parent
clocks.
Since commit fdb1bffe28 ("clk: scmi: Postpone clock name resolution"),
all scmi clocks are named by default "scmi-%zu" until they are enabled,
it breaks clocks registration and boot process for STM32MP13/25
platforms.
Rework the STM32 core clock driver and STM32MP13/25 clock description
to use clock index instead of their real name.
Introduce struct clk_parent_data which allows to identify parent clock
either by index or by name. Name is only used for particular clocks
provided by IP which are clock provider as i2s/i2s_ckin, usb0/ck_usbo_48m,
and ltdc/ck_ker_ltdc.
STM32_GATE() and STM32_COMPOSITE_NOMUX macros are updated in order to
use parent clock index.
As STM32MP13 supports both SPL and SCMI boot, keep using an array
with clock's name for SPL.

As of v2026.01, no platforms contain any rel.dyn sections in their xPL
phase images. Their inclusion in linker scripts initially was an
oversight as part of taking the full U-Boot linker scripts and modifying
them down. Then in commit 8b0ebe054b ("arm: Update linker scripts to
ensure appended device tree is aligned") these sections were used to
force correct alignment for the device tree. This however, lead to a
different problem.
That problem is that when we do not have a separate BSS section in SPL
we instead would overlay the BSS with the rel.dyn section, in the common
linker script case. This in turn lead to creating an incorrectly sized
BSS "pad" file sometimes (depending on arbitrary changes within the rest
of the binary itself). This in turn lead to the dtb being in the wrong
location in the binary and not found at run time.
This commit fixes a few things:
- Remove the rel.dyn section from all ARM SPL linker scripts.
- In turn, this moves the dtb alignment statement in to another section.
- For ast2600 which uses CONFIG_POSITION_INDEPENDENT we need to keep the
symbols however.

Markus Schneider-Pargmann (TI.com) <msp@baylibre.com> says:
musb currently uses a wrapper driver that binds on the parent device of
the actual musb devices to manage the differentiation between gadget and
host modes. However in the upstream devicetree this parent devicetree
node can not be used to match the wrapper driver.
To be able to probe the musb devices in host/gadget mode directly, this
series introduces support for returning -ENODEV in bind functions
resulting in iterating the remaining drivers potentially binding to
other drivers that match the compatible.

The loop in lists_bind_fdt uses an indented style for log messages
within the loop and normal messages for errors that lead to the exit of

for continuation on -ENODEV returned by bind, the log message should be
indented.

Currently once a driver matched the compatible string of a device, other
drivers are ignored. If the first matching driver returns -ENODEV, no
other possibly matching drivers are iterated with that compatible of the
device. Instead the next compatible in the list of compatibles is
selected, assuming only one driver matches one compatible at a time.
To be able to use the bind function to return -ENODEV and continue
matching other drivers with the same compatible, move the for loop a bit
to continue the for loop after -ENODEV was returned. The loop had to be
adjusted a bit to still support the 'drv' argument properly. Some
simplifications were done as well.
The modification will only add additional loop iterations if -ENODEV is
returned. Otherwise the exit and continue conditions for the loop stay
the same and do not cause any additional iterations and should not
impact performance.
This is required for ti-musb-host and ti-musb-peripheral which both
match on the same device but differ based on the dr_mode DT property.
Depending on this property, the driver is either UCLASS_USB or
UCLASS_USB_GADGET_GENERIC. By checking the DT property in the bind
function and returning -ENODEV the other driver can probe instead.
