Hello all v4: https://lore.kernel.org/linux-media/20210103231235.792999-1-djrscally@xxxxxxxxx/T/#m11b7cb977e1b73fba1e625c3d6a189e2943a7783 v3: https://lore.kernel.org/linux-media/20201224010907.263125-1-djrscally@xxxxxxxxx/T/#m37b831bb2b406917d6db5da9acf9ed35df65d72d v2: https://lore.kernel.org/linux-media/20201217234337.1983732-1-djrscally@xxxxxxxxx/T/#md93fd090009b42a6a98aed892aff0d38cf07e0cd v1: https://lore.kernel.org/linux-media/20201130133129.1024662-1-djrscally@xxxxxxxxx/T/#m91934e12e3d033da2e768e952ea3b4a125ee3e67 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 Andy Shevchenko (1): media: ipu3-cio2: Add headers that ipu3-cio2.h is direct user of Daniel Scally (13): software_node: Fix refcounts in software_node_get_next_child() device property: Return true in fwnode_device_is_available for NULL ops device 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 device property: Define format macros for ports and endpoints lib/test_printf.c: Use helper function to unwind array of software_nodes ipu3-cio2: Add T: entry to MAINTAINERS ipu3-cio2: Rename ipu3-cio2.c media: v4l2-core: v4l2-async: Check sd->fwnode->secondary in match_fwnode() ACPI / bus: Add acpi_dev_get_next_match_dev() and helper macro media: v4l2-fwnode: Include v4l2_fwnode_bus_type ipu3-cio2: Add cio2-bridge to ipu3-cio2 driver Heikki Krogerus (1): software_node: Add support for fwnode_graph*() family of functions MAINTAINERS | 2 + drivers/acpi/utils.c | 30 +- drivers/base/property.c | 15 +- drivers/base/swnode.c | 180 ++++++++-- drivers/media/pci/intel/ipu3/Kconfig | 18 + drivers/media/pci/intel/ipu3/Makefile | 3 + drivers/media/pci/intel/ipu3/cio2-bridge.c | 311 ++++++++++++++++++ drivers/media/pci/intel/ipu3/cio2-bridge.h | 125 +++++++ .../ipu3/{ipu3-cio2.c => ipu3-cio2-main.c} | 34 ++ drivers/media/pci/intel/ipu3/ipu3-cio2.h | 24 ++ drivers/media/v4l2-core/v4l2-async.c | 8 + drivers/media/v4l2-core/v4l2-fwnode.c | 11 - include/acpi/acpi_bus.h | 7 + include/linux/fwnode.h | 7 + include/media/v4l2-fwnode.h | 22 ++ lib/test_printf.c | 4 +- 16 files changed, 763 insertions(+), 38 deletions(-) create mode 100644 drivers/media/pci/intel/ipu3/cio2-bridge.c create mode 100644 drivers/media/pci/intel/ipu3/cio2-bridge.h rename drivers/media/pci/intel/ipu3/{ipu3-cio2.c => ipu3-cio2-main.c} (98%) -- 2.25.1
