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.

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. Therefore in current state the devices are used only in read-only mode and have trivial bindings, so document them to have basic dtschema tests.

Niklas Söderlund authored
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.

Ulf Hansson authored
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. The proper behaviour is to start at the node's parent, so let's do that. While at it, let's take the opportunity to update the description of the 'node_not_dev' flag, as to clarify its purpose.

Add Kconfig support for -Wimplicit-fallthrough for both GCC and Clang. The compiler option is under configuration CC_IMPLICIT_FALLTHROUGH, which is enabled by default. 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/236Co-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.
