Merge tag 'driver-core-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core updates from Greg KH: "Here is the "big" set of driver core patches for 5.5-rc1 There's a few minor cleanups and fixes in here, but the majority of the patches in here fall into two buckets: - debugfs api cleanups and fixes - driver core device link support for boot dependancy issues The debugfs api cleanups are working to slowly refactor the debugfs apis so that it is even harder to use incorrectly. That work has been happening for the past few kernel releases and will continue over time, it's a long-term project/goal The driver core device link support missed 5.4 by just a bit, so it's been sitting and baking for many months now. It's from Saravana Kannan to help resolve the problems that DT-based systems have at boot time with dependancy graphs and kernel modules. Turns out that no one has actually tried to build a generic arm64 kernel with loads of modules and have it "just work" for a variety of platforms (like a distro kernel). The big problem turned out to be a lack of dependency information between different areas of DT entries, and the work here resolves that problem and now allows devices to boot properly, and quicker than a monolith kernel. All of these patches have been in linux-next for a long time with no reported issues" * tag 'driver-core-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (68 commits) tracing: Remove unnecessary DEBUG_FS dependency of: property: Add device link support for interrupt-parent, dmas and -gpio(s) debugfs: Fix !DEBUG_FS debugfs_create_automount of: property: Add device link support for "iommu-map" of: property: Fix the semantics of of_is_ancestor_of() i2c: of: Populate fwnode in of_i2c_get_board_info() drivers: base: Fix Kconfig indentation firmware_loader: Fix labels with comma for builtin firmware driver core: Allow device link operations inside sync_state() driver core: platform: Declare ret variable only once cpu-topology: declare parse_acpi_topology in <linux/arch_topology.h> crypto: hisilicon: no need to check return value of debugfs_create functions driver core: platform: use the correct callback type for bus_find_device firmware_class: make firmware caching configurable driver core: Clarify documentation for fwnode_operations.add_links() mailbox: tegra: Fix superfluous IRQ error message net: caif: Fix debugfs on 64-bit platforms mac80211: Use debugfs_create_xul() helper media: c8sectpfe: no need to check return value of debugfs_create functions of: property: Add device link support for iommus, mboxes and io-channels ...
