dev_read_s32_default is for getting an s32 from a Device Tree property
and allows to take a default value if that property is missing.

Considering it calls ofnode_read_u32_default which takes a u32 and
returns a u32, it should do the same instead of using an int, especially
considering that int size is typically architecture-specific, as opposed
to s32/u32.

s32 and u32 being the same size, dev_read_s32* functions calling
ofnode_read_u32_default shouldn't be an issue (at the type level at
least) as the information will be stored appropriately in 4B regardless
of the sign.

This incidentally matches all other dev_read_*_default functions.

There are already several helpers to find a udevice based on its
position in a device tree, like getting a child or a node pointed by a
phandle, but there was no support for graph endpoints, which are very
common in display pipelines.

Add a new helper, named uclass_get_device_by_endpoint() which enters the
child graph reprensentation, looks for a specific port, then follows the
remote endpoint, and finally retrieves the first parent of the given
uclass_id.

This is a very handy and straightforward way to get a bridge or a panel
handle.

Caleb Connolly <caleb.connolly@linaro.org> says:

In Simon's series reworking autoprobe, a discussion came up about
DM_FLAG_PROBE_AFTER_BIND, specifically that it wasn't very clear where
this flag should be used.

This series implements my suggestions made there to clarify the use of
this flag, and fixup the two driver which erroneously apply it to their
driver struct (this does nothing).

Link: https://lore.kernel.org/r/20250117-clarify-probe-after-bind-v1-0-273f046ce5dd@linaro.org

The DM_FLAG_PROBE_AFTER_BIND flag only makes sense on a per-device
basis, however recently added documentation as well as some confused
drivers imply that it might be added to a driver definition, this does
nothing.

Clarify the new documentation and expand on the comment by the
definition to point people in the right direction.

Depending on the platform, there may be multiple clock sources
required to enable a UART.  Use the bulk functions to get and
enable the clocks when the UART probes.  This can facilitate
the removal of functions to manually enable the clock.

This is made dependent on CLK_CCF which is used on imx6q,
imx8m[mnqp], several imxrt, imx9.  If/when the UART clock
registration is done for older boards, this limitation
could be updated.
