git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux Pull devicetree updates from Rob Herring: - Add Krzysztof Kozlowski as co-maintainer for DT bindings providing much needed help. - DT schema validation now takes DTB files as input rather than intermediate YAML files. This decouples the validation from the source level syntax information. There's a bunch of schema fixes as a result of switching to DTB based validation which exposed some errors and incomplete schemas and examples. - Kbuild improvements to explicitly warn users running 'make dt_binding_check' on missing yamllint - Expand DT_SCHEMA_FILES kbuild variable to take just a partial filename or path instead of the full path to 1 file. - Convert various bindings to schema format: mscc,vsc7514-switch, multiple GNSS bindings, ahci-platform, i2c-at91, multiple UFS bindings, cortina,gemini-sata-bridge, cortina,gemini-ethernet, Atmel SHA, Atmel TDES, Atmel AES, armv7m-systick, Samsung Exynos display subsystem, nuvoton,npcm7xx-timer, samsung,s3c2410-i2c, zynqmp_dma, msm/mdp4, rda,8810pl-uart - New schemas for u-boot environment variable partition, TI clksel - New compatible strings for Renesas RZ/V2L SoC - Vendor prefixes for Xen, HPE, deprecated Synopsys, deprecated HiSilicon - Add/fix schemas for QEMU Arm 'virt' machine - Drop unused of_alias_get_alias_list() function - Add a script to check DT unittest EXPECT message output.

2022-03-02dt-bindings: Another pass removing cases of 'allOf' containing a '$ref'Rob Herring1-2/+1
Another pass at removing unnecessary use of 'allOf' with a '$ref'. json-schema versions draft7 and earlier have a weird behavior in that any keywords combined with a '$ref' are ignored (silently). The correct form was to put a '$ref' under an 'allOf'. This behavior is now changed in the 2019-09 json-schema spec and '$ref' can be mixed with other keywords.

2022-02-21dt-bindings: mtd: spi-nor: Allow two CS per deviceMiquel Raynal1-1/+2
The Xilinx QSPI controller has two advanced modes which allow the controller to behave differently and consider two flashes as one single storage. One of these two modes is quite complex to support from a binding point of view and is the dual parallel memories. In this mode, each byte of data is stored in both devices: the even bits in one, the odd bits in the other. The split is automatically handled by the QSPI controller and is transparent for the user. The other mode is simpler to support, it is called dual stacked memories. The controller shares the same SPI bus but each of the devices contain half of the data. Once in this mode, the controller does not follow CS requests but instead internally wires the two CS levels with the value of the most significant address bit. Supporting these two modes will involve core changes which include the possibility of providing two CS for a single SPI device Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> Acked-by: Rob Herring <robh@kernel.org> Reviewed-by: Pratyush Yadav <p.yadav@ti.com> Link: https://lore.kernel.org/r/20220126112608.955728-2-miquel.raynal@bootlin.com Signed-off-by: Mark Brown <broonie@kernel.org>

2021-12-01dt-bindings: mtd: spi-nor: Add a reference to spi-peripheral-props.yamlPratyush Yadav1-1/+2
The spi-peripheral-props.yaml schema contains peripheral-specific properties for SPI controllers that should be present in the peripheral node. Add a reference to that so its constraints are followed. additionalProperties: false cannot be used since it marks the controller properties as unknown. Use unevaluatedProperties: false instead. This has the side effect of allowing extra properties that are not specified in the schema. The alternative is to list all the controller properties in this schema but that would mean every peripheral binding would have to repeat the same set of properties for each controller.

2021-07-15dt-bindings: More dropping redundant minItems/maxItemsRob Herring1-8/+0
Another round of removing redundant minItems/maxItems from new schema in the recent merge window. If a property has an 'items' list, then a 'minItems' or 'maxItems' with the same size as the list is redundant and can be dropped. Note that is DT schema specific behavior and not standard json-schema behavior. The tooling will fixup the final schema adding any unspecified minItems/maxItems. This condition is partially checked with the meta-schema already, but only if both 'minItems' and 'maxItems' are equal to the 'items' length. An improved meta-schema is pending.

On a typical end product, a vendor may choose to secure some regions in the NAND memory which are supposed to stay intact between FW upgrades. The access to those regions will be blocked by a secure element like Trustzone. So the normal world software like Linux kernel should not touch these regions (including reading). So let's add a property for declaring such secure regions so that the drivers can skip touching them.
