9bf3fc5007 Merge tag 'devicetree-for-5.18' of 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. Pass
   messages also now print by default at PR_INFO level to help test
   automation.

dca669354e dt-bindings: Another pass removing cases of 'allOf' containing a '$ref'
Another pass at removing unnecessary use of 'allOf' with a '$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.

b252ada293 dt-bindings: mtd: spi-nor: Allow two CS per device
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

See commit a10d862e58 ("ARM: dts: Fix the DNS-313 flash compatible")
The flash on the DNS-313 needs to be probed as JEDEC, it does not conform to the common CFI standard.

e9d7c323cf dt-bindings: mtd: spi-nor: Add a reference to spi-peripheral-props.yaml
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.

778cb8e39f dt-bindings: mtd: gpmc: Fix the ECC bytes vs. OOB bytes equation
"PAGESIZE / 512" is the number of ECC chunks.
"ECC_BYTES" is the number of bytes needed to store a single ECC code.
"2" is the space reserved by the bad block marker.

"2 + (PAGESIZE / 512) * ECC_BYTES" should of course be lower or equal
than the total number of OOB bytes, otherwise it won't fit.

Fix the equation by substituting s/>=/<=/.

e8917266ae dt-bindings: More dropping redundant minItems/maxItems
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.

63f8e9e0ac dt-bindings: mtd: Convert mtd-physmap to DT schema
Convert the mtd-physmap binding to DT schema format. The arm-versatile,
cypress,hyperflash and intel,ixp4xx-flash are all just an additional
compatible string, so they are all merged into the main schema.

There doesn't appear to be any users nor support for 'vendor-id' and
'device-id', so these have been dropped.

6b562738a2 dt-binding: mtd: nand: Document the cs-gpios property
To reach higher capacities, arrays of chips are now pretty common.
Unfortunately, most of the controllers have been designed a decade ago
and did not all anticipate the need for several chip-selects. The new
cs-gpios property allows to workaround this limitation by adding as many
GPIO chip-select as needed.

27736ddd24 dt-bindings: mtd: brcmnand: convert to the json-schema
This helps validating DTS files.

Changes that require mentioning:
1. Property "clock" was renamed to "clocks"
2. Duplicated properties (defined in nand-controller.yaml) were dropped
3. Compatible "brcm,nand-bcm63168" was added
4. SoC specific "compatible" cases got limited controller versions

Examples changes:
1. Nodes "nand" were renamed to "nand-controller"
2. Nodes "nandcs" were renamed to "nand"
3. Dropped partitions as they were using old syntax and are well
   documented elsewhere anyway

This rewritten binding validates cleanly using the "dt_binding_check".
Some Linux stored DTS files will require updating to make "dtbs_check"
happy.

ee590106c3 dt-bindings: mtd: Add a property to declare secure regions in NAND chips
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.
