Summary: - kbuild cleanups and improvements for dtbs - Code clean-up of overlay code and fixing for some long standing memory leak and race condition in applying overlays - Improvements to DT memory usage making sysfs/kobjects optional and skipping unflattening of disabled nodes. This is part of kernel tinification efforts. - Final piece of removing storing the full path for every DT node. The prerequisite conversion of printk's to use device_node format specifier happened in 4.14. - Sync with current upstream dtc. This brings additional checks to dtb compiling. - Binding doc tree wide removal of leading 0s from examples - RTC binding documentation adding missing devices and some consolidation of duplicated bindings - Vendor prefix documentation for nutsboard, Silicon Storage Technology, shimafuji, Tecon Microprocessor Technologies, DH electronics GmbH, Opal Kelly, and Next Thing" * tag 'devicetree-for-4.15' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (55 commits) dt-bindings: usb: add #phy-cells to usb-nop-xceiv dt-bindings: Remove leading zeros from bindings notation kbuild: handle dtb-y and CONFIG_OF_ALL_DTBS natively in Makefile.lib MIPS: dts: remove bogus bcm96358nb4ser.dtb from dtb-y entry kbuild: clean up *.dtb and *.dtb.S patterns from top-level Makefile .gitignore: move *.dtb and *.dtb.S patterns to the top-level .gitignore .gitignore: sort normal pattern rules alphabetically dt-bindings: add vendor prefix for Next Thing Co. scripts/dtc: Update to upstream version v1.4.5-6-gc1e55a5513e9 of: dynamic: fix memory leak related to properties of __of_node_dup of: overlay: make pr_err() string unique of: overlay: pr_err from return NOTIFY_OK to overlay apply/remove of: overlay: remove unneeded check for NULL kbasename() of: overlay: remove a dependency on device node full_name of: overlay: simplify applying symbols from an overlay of: overlay: avoid race condition between applying multiple overlays of: overlay: loosen overly strict phandle clash check of: overlay: expand check of whether overlay changeset can be removed of: overlay: detect cases where device tree may become corrupt of: overlay: minor restructuring ...
| * dt-bindings: usb: add #phy-cells to usb-nop-xceivRob Herring2017-11-131-0/+2
| | | | | | | | | | | | | | | | | | Consumers of usb-nop-xceiv use the phy binding, but #phy-cells is missing from the binding. This is probably because this binding predates the common phy binding. So add #phy-cells as a required property. This should not break any users as missing should be treated as 0 cells. Signed-off-by: Rob Herring <robh@kernel.org>

| | * kbuild: handle dtb-y and CONFIG_OF_ALL_DTBS natively in Makefile.libMasahiro Yamada2017-11-1048-182/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If CONFIG_OF_ALL_DTBS is enabled, "make ARCH=arm64 dtbs" compiles each DTB twice; one from arch/arm64/boot/dts/*/Makefile and the other from the dtb-$(CONFIG_OF_ALL_DTBS) line in arch/arm64/boot/dts/Makefile. It could be a race problem when building DTBS in parallel. Another minor issue is CONFIG_OF_ALL_DTBS covers only *.dts in vendor sub-directories, so this broke when Broadcom added one more hierarchy in arch/arm64/boot/dts/broadcom/<soc>/. One idea to fix the issues in a clean way is to move DTB handling to Kbuild core scripts. Makefile.dtbinst already recognizes dtb-y natively, so it should not hurt to do so. Add $(dtb-y) to extra-y, and $(dtb-) as well if CONFIG_OF_ALL_DTBS is enabled. All clutter things in Makefiles go away. As a bonus clean-up, I also removed dts-dirs. Just use subdir-y directly to traverse sub-directories.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "%pOF" printf format was recently added to print the full name of a device tree node, with the intent of changing the node full_name field to contain only the node name instead of the full path of the node. dup_and_fixup_symbol_prop() duplicates a property from the "/__symbols__" node of an overlay device tree. The value of each duplicated property must be fixed up to include the full path of a node in the live device tree. The current code uses the node's full_name for that purpose. Update the code to use the "%pOF" printf format to determine the node's full path. Signed-off-by: Frank Rowand <frank.rowand@sony.com> Signed-off-by: Rob Herring <robh@kernel.org>

After recent restructuring of the overlay apply code, it is easier to disintangle the code that applies the symbols, and to make the overlay changeset creation code more straight forward and understandable.

Add a mutex to prevent multiple overlay applies from occurring simultaneously. Move of_resolve_phandles() into of_overlay_apply() so that it does not have to be duplicated by each caller of of_overlay_apply(). The test in of_resolve_phandles() that the overlay tree is detached is temporarily disabled so that old style overlay unittests do not fail.

When an attempt to remove an overlay changeset fails, an effort is made to re-apply any partial reversion of the changeset. The existing code does not check for failure to recover a failed overlay changeset application or overlay changeset revert. Add the missing checks and flag the devicetree as corrupt if the state of the devicetree can not be determined. Improve and expand the returned errors to more fully reflect the result of the effort to undo the partial effects of a failed attempt to apply or remove an overlay changeset. If the device tree might be corrupt, do not allow further attempts to apply or remove an overlay changeset. When creating an overlay changeset from an overlay device tree, add some additional warnings if the state of the overlay device tree is not as expected.
