When every member of a linker list is aligned by the compiler, we can no
longer rely on the sizeof of the struct to determine the number of
entries.

For example, if the struct size is 0x90 but every entry is aligned to 0xa0
by the compiler, the linker list entries takes more space in memory and
the calculation of the number of entries is incorrect. For example, we may
see 0x12 entries when there are only 0x11.

This is a real problem. There may be a general solution, although I cannot
currently think of one. So far it only bites with OF_PLATDATA_RT which
creates a pointer to each entry of the 'struct udevice' linker_list. This
does not happen without that option, so it only affects SPL.

Work around it by manually calculating the aligned size of struct udevice,
then using that for the n_ent calculation.

Note: the alignment fix to linker list was here:

At present if devres is enabled in U-Boot proper it is enabled in SPL.
We don't normally want it there, so disable it.

This is controlled by the DM_EVENT config option.

Sphinx expects Return: and not @return to indicate a return value.

The commit 3ad307784847 ("dm: core: device: enable power domain in probe")
introduced enabling power domain when device is probed.
By checking this sequence in Linux kernel was found that power domain is
handled first followed by pinctrl setting.

This patch is switching this order to follow Linux kernel that power
domains are handled first follow by pinctrl setting.

The issue was found on Xilinx Kria SOM where firmware is blocking setting
up pin configuration/muxes without enabling power domain for the specific
IP first.

Add a message on probe in driver model core when the default

This message is displayed only when the pinctrl API is

In some cases it is useful to search just by a partial name, such as
when looking for a sibling device that has a common name substring. Add
helper functions to handle these requirements.

This uclass is intended to manage IOMMUs on systems where the
IOMMUs are not in bypass mode by default.  In that case U-Boot
cannot ignore the IOMMUs if it wants to use devices that need
to do DMA and sit behind such an IOMMU.

This initial IOMMU uclass implementation does not implement and
device ops and is intended for IOMMUs that have a bypass mode
that does not require address translation.  Support for IOMMUs
that do require address translation is planned and device ops
will be defined when support for such IOMMUs will be added.
