Subject[PATCH v5 00/15] Add functionality to ipu3-cio2 driver allowing software_node connections to sensors on platforms designed for Windows
Date

Hello all

v4:
https://lore.kernel.org/linux-media/20210103231235.792999-1-djrscally@gmail.com/T/#m11b7cb977e1b73fba1e625c3d6a189e2943a7783

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
