This problem has two main parts; the first part, which is handled in this series, is extending the ipu3-cio2 driver to allow for patching the firmware via software_nodes if endpoints aren't defined by ACPI. The second is adding a new driver to handle power, clocks and GPIO pins defined in DSDT tables in an awkward way. I decided to split that second part out from this series, and instead give it its own series (a v2 of which should land "soon"). The reasons for that are: 1. It's a logically separate change anyway 2. The recipients list was getting really long and 3. That probably meant that handling merge for all of this in one go was going to be impractically awkward. 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 (with an ack already) 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: - Added patch 13/14 to define an enum in media/v4l2-fwnode.h - Added patch 06/14 to define name formats for fwnode graph ports and endpoints More details of changes on each patch.
