2021-12-06dt-bindings: Only show unique unit address warning for enabled nodesSam Protsenko
There are valid cases when two nodes can have the same address. For example, in Exynos SoCs there is USI IP-core, which might be configured to provide UART, SPI or I2C block, all of which having the same base register address. But only one can be enabled at a time. That looks like this: usi@138200c0 { serial@13820000 { status = "okay"; }; i2c@13820000 { status = "disabled"; }; }; When running "make dt_binding_check", it reports next warning: Warning (unique_unit_address): /example-0/usi@138200c0/serial@13820000: duplicate unit-address (also used in node /example-0/usi@138200c0/i2c@13820000) Disable "unique_unit_address" in DTC_FLAGS to suppress warnings like that, but enable "unique_unit_address_if_enabled" warning, so that dtc still reports a warning when two enabled nodes are having the same address.

2021-12-03dt-bindings: media: nxp,imx7-mipi-csi2: Drop bad if/then schemaRob Herring
The if/then schema for 'data-lanes' doesn't work as 'compatible' is at a different level than 'data-lanes'. To make it work, the if/then schema would have to be moved to the top level and then whole hierarchy of nodes down to 'data-lanes' created. I don't think it is worth the complexity to do that, so let's just drop it. The error in this schema is masked by a fixup in the tools causing the 'allOf' to get overwritten. Removing the fixup as part of moving to json-schema draft 2019-09 revealed the issue: Documentation/devicetree/bindings/media/nxp,imx7-mipi-csi2.example.dt.yaml: mipi-csi@30750000: ports:port@0:endpoint:data-lanes:0: [1] is too short From schema: /builds/robherring/linux-dt-review/Documentation/devicetree/bindings/media/nxp,imx7-mipi-csi2.yaml Documentation/devicetree/bindings/media/nxp,imx7-mipi-csi2.example.dt.yaml: mipi-csi@32e30000: ports:port@0:endpoint:data-lanes:0: [1, 2, 3, 4] is too long From schema: /builds/robherring/linux-dt-review/Documentation/devicetree/bindings/media/nxp,imx7-mipi-csi2.yaml The if condition was always true because 'compatible' did not exist in 'endpoint' node and a non-existent property is true for json-schema.

2021-12-03of/irq: Add a quirk for controllers with their own definition of interrupt-mapMarc Zyngier
Since commit 041284181226 ("of/irq: Allow matching of an interrupt-map local to an interrupt controller"), a handful of interrupt controllers have stopped working correctly. This is due to the DT exposing a non-sensical interrupt-map property, and their drivers relying on the kernel ignoring this property. Since we cannot realistically fix this terrible behaviour, add a quirk for the limited set of devices that have implemented this monster, and document that this is a pretty bad practice.

Allow fully disabling CPU nodes using status = "fail". This allows a bootloader to change the number of available CPUs (for example when a common DTS is used for SoC variants with different numbers of cores) without deleting the nodes altogether, which could require additional fixups to avoid dangling phandle references. Unknown status values (everything that is not "okay"/"ok", "disabled" or "fail"/"fail-...") will continue to be interpreted like "disabled", meaning that the CPU can be enabled during boot.

Few Texas Instruments DC-DC converters on PMBus like TPS544B20 do not have bindings and are used only as hardware monitoring sensor. These devices are actually not trivial and can receive basic configuration (e.g. power up mode, CNTL pin polarity, expected input voltage), however devicetree support for configuration was never added.

2021-11-29dt-bindings: thermal: Fix definition of cooling-maps contribution propertyNiklas Söderlund
When converting the thermal-zones bindings to yaml the definition of the contribution property changed. The intention is the same, an integer value expressing a ratio of a sum on how much cooling is provided by the device to the zone. But after the conversion the integer value is limited to the range 0 to 100 and expressed as a percentage. This is problematic for two reasons. - This do not match how the binding is used. Out of the 18 files that make use of the property only two (ste-dbx5x0.dtsi and ste-hrefv60plus.dtsi) sets it at a value that satisfy the binding, 100. The remaining 16 files set the value higher and fail to validate. - Expressing the value as a percentage instead of a ratio of the sum is confusing as there is nothing to enforce the sum in the zone is not greater then 100. This patch restore the pre yaml conversion description and removes the value limitation allowing the usage of the bindings to validate.

In the struct supplier_bindings the member 'node_not_dev' is described as "The consumer node containing the property is never a device.", but that is inconsistent with the behaviour of the code in of_link_property(), as it calls of_get_compat_node() that starts parsing for a compatible property from the node it gets passed to it.

Special thanks to Nathan Chancellor who fixed the Clang bug[1][2]. This bugfix only appears in Clang 14.0.0, so older versions still contain the bug and -Wimplicit-fallthrough won't be enabled for them, for now. This concludes a long journey and now we are finally getting rid of the unintentional fallthrough bug-class in the kernel, entirely. :) Link: https://github.com/llvm/llvm-project/commit/9ed4a94d6451046a51ef393cd62f00710820a7e8 [1] Link: https://bugs.llvm.org/show_bug.cgi?id=51094 [2] Link: https://github.com/KSPP/linux/issues/115 Link: https://github.com/ClangBuiltLinux/linux/issues/236 Co-developed-by: Kees Cook <keescook@chromium.org> Signed-off-by: Kees Cook <keescook@chromium.org> Co-developed-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Gustavo A.

Pull xfs cleanups from Darrick Wong: "The most 'exciting' aspect of this branch is that the xfsprogs maintainer and I have worked through the last of the code discrepancies between kernel and userspace libxfs such that there are no code differences between the two except for #includes. IOWs, diff suffices to demonstrate that the userspace tools behave the same as the kernel, and kernel-only bits are clearly marked in the /kernel/ source code instead of just the userspace source. Summary: - Clean up open-coded swap() calls. - A little bit of #ifdef golf to complete the reunification of the kernel and userspace libxfs source code" * tag 'xfs-5.16-merge-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: xfs: sync xfs_btree_split macros with userspace libxfs xfs: #ifdef out perag code for userspace xfs: use swap() to make dabtree code cleaner

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull irq fixes from Thomas Gleixner: "A set of fixes for the interrupt subsystem Core code: - A regression fix for the Open Firmware interrupt mapping code where a interrupt controller property in a node caused a map property in the same node to be ignored. Interrupt chip drivers: - Workaround a limitation in SiFive PLIC interrupt chip which silently ignores an EOI when the interrupt line is masked. - Provide the missing mask/unmask implementation for the CSKY MP interrupt controller. PCI/MSI: - Prevent a use after free when PCI/MSI interrupts are released by destroying the sysfs entries before freeing the memory which is accessed in the sysfs show() function. - Implement a mask quirk for the Nvidia ION AHCI chip which does not advertise masking capability despite implementing it. Even worse the chip comes out of reset with all MSI entries masked, which due to the missing masking capability never get unmasked. - Move the check which prevents accessing the MSI[X] masking for XEN back into the low level accessors. The recent consolidation missed that these accessors can be invoked from places which do not have that check which broke XEN. Move them back to he original place instead of sprinkling tons of these checks all over the code" * tag 'irq-urgent-2021-11-14' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: of/irq: Don't ignore interrupt-controller when interrupt-map failed irqchip/sifive-plic: Fixup EOI failed when masked irqchip/csky-mpintc: Fixup mask/unmask implementation PCI/MSI: Destroy sysfs before freeing entries PCI: Add MSI masking quirk for Nvidia ION AHCI PCI/MSI: Deal with devices lying about their MSI mask capability PCI/MSI: Move non-mask check back into low level accessors
