This series is to start adding support for webcams on laptops with ACPI tables
designed for use with CIO2 on Windows. This series extends the ipu3-cio2
driver to allow for patching the firmware via software_nodes if endpoints
aren't defined by ACPI.

I'm hopeful that most or all of this series could get picked up for 5.12.
We touch a few different areas (listed below), but I think the easiest
approach would be to merge everything through media tree. Rafael, Greg,
Mauro and Sergey; are you ok with that plan, or would you prefer a
different approach? Mauro; if that plan is ok (and of course assuming that
the rest of the patches are acked by their respective maintainers) could
we get a dedicated feature branch just in case the following series ends
up being ready in time too?

lib
  lib/test_printf.c: Use helper function to unwind array of
    software_nodes

base
  software_node: Fix refcounts in software_node_get_next_child()
  property: Return true in fwnode_device_is_available for NULL ops
  property: Call fwnode_graph_get_endpoint_by_id() for fwnode->secondary
  software_node: Enforce parent before child ordering of nodes arrays
  software_node: unregister software_nodes in reverse order
  include: fwnode.h: Define format macros for ports and endpoints

acpi
  acpi: Add acpi_dev_get_next_match_dev() and helper macro

media
  media: v4l2-core: v4l2-async: Check sd->fwnode->secondary in
    match_fwnode()
  ipu3-cio2: Add T: entry to MAINTAINERS
  ipu3-cio2: Rename ipu3-cio2.c
  ipu3-cio2: Add cio2-bridge to ipu3-cio2 driver
  include: media: v4l2-fwnode: Include v4l2_fwnode_bus_type

Series-level changelog:
	- Rebased onto 5.11-rc1

Thanks
Dan
