2024-08-21dt-bindings: memory-controllers: renesas,rpc-if: add top-level constraintsKrzysztof Kozlowski
Properties with variable number of items per each device are expected to have widest constraints in top-level "properties:" block and further customized (narrowed) in "if:then:". Add missing top-level constraints for clocks.

2024-08-08dt-bindings: memory-controllers: fsl,imx-weim: Fix "fsl,weim-cs-timing" schemaRob Herring (Arm)
The "fsl,weim-cs-timing" property is an array, but the constraints in the if/then schema are for a matrix. That worked fine when all properties were decoded into a matrix, but now dtschema decodes properties into scalars and arrays based on their type.

2024-04-05dt-bindings: treewide: add access-controllers descriptionGatien Chevallier
access-controllers is an optional property that allows a peripheral to refer to one or more domain access controller(s). Description of this property is added to all peripheral binding files of the peripheral under the STM32 firewall controller. It allows an accurate representation of the hardware, where various peripherals are connected to a firewall bus. The firewall can then check the peripheral accesses before allowing its device to probe.

2024-02-27dt-bindings: memory-controller: st,stm32: add MP25 supportChristophe Kerello
Add a new compatible string to support MP25 SoC. On MP1 SoC, RNB signal (NAND controller signal) and NWAIT signal (PSRAM controller signal) have been integrated together in the SoC. That means that the NAND controller and the PSRAM controller (if the signal is used) can not be used at the same time. On MP25 SoC, the 2 signals can be used outside the SoC, so there is no more restrictions. MP1 SoC also embeds revision 1.1 of the FMC2 IP when MP25 SoC embeds revision 2.0 of the FMC2 IP. MP25 SoC is also using PSCI OS-initiated mode, so allow a single 'power-domains' entry for STM32 FMC2. As MP1 will move on PSCI OS-initiated mode, add this property as optional for all FMC2 variants.

Pull ARM SoC devicetree updates from Arnd Bergmann: "The biggest change this time is for the 32-bit devicetree files, which are all moved to a new location, using separate subdirectories for each SoC vendor, following the same scheme that is used on arm64, mips and riscv. This has been discussed for many years, but so far we never did this as there was a plan to move the files out of the kernel entirely, which has never happened. The impact of this will be that all external patches no longer apply, and anything depending on the location of the dtb files in the build directory will have to change. The installed files after 'make dtbs_install' keep the current location. There are six added SoCs here that are largely variants of previously added chips. Two other chips are added in a separate branch along with their device drivers. - The Samsung Exynos 4212 makes its return after the Samsung Galaxy Express phone is addded at last. The SoC support was originally added in 2012 but removed again in 2017 as it was unused at the time. - Amlogic C3 is a Cortex-A35 based smart IP camera chip - Qualcomm MSM8939 (Snapdragon 615) is a more featureful variant of the still common MSM8916 (Snapdragon 410) phone chip that has been supported for a long time. - Qualcomm SC8180x (Snapdragon 8cx) is one of their earlier high-end laptop chips, used in the Lenovo Flex 5G, which is added along with the reference board. - Qualcomm SDX75 is the latest generation modem chip that is used as a peripherial in phones but can also run a standalone Linux. Unlike the prior 32-bit SDX65 and SDX55, this now has a 64-bit Cortex-A55. - Alibaba T-Head TH1520 is a quad-core RISC-V chip based on the Xuantie C910 core, a step up from all previously added rv64 chips.

Both are different configurations of the same IP with support for different types of memory interfaces. The 'arm,pl354' binding has already been in use upstream for a long time in Arm development boards. The existing users have only the controller without any child devices, so drop the required address properties (ranges, #address-cells, #size-cells). The schema for 'ranges' is too constrained as the order is not important and the PL354 has 8 chipselects (And the PL353 actually has up to 8 too). The clocks aren't really correct in either case.

2022-10-18dt-bindings: memory: Add jedec,lpddrX-channel bindingJulius Werner
This patch adds a new device tree binding for an LPDDR channel to serve as a top-level organizing node for LPDDR part nodes nested below it. An LPDDR channel needs to have an "io-width" property to describe its width (this is important because this width does not always match the io-width of the part number, indicating that multiple parts are wired in parallel on the same channel), as well as one or more nested "rank@X" nodes. Those represent information about the individual ranks of each LPDDR part connected on that channel and should match the existing "jedec,lpddrX" bindings for individual LPDDR parts. New platforms should be using this node -- the existing practice of providing a raw, toplevel "jedec,lpddrX" node without indication of how many identical parts are in the system should be considered deprecated.

2022-10-18dt-bindings: memory: Add numeric LPDDR compatible string variantJulius Werner
This patch allows a new kind of compatible string for LPDDR parts in the device tree bindings, in addition to the existing hardcoded <vendor>,<part-number> strings. The new format contains manufacturer and part (revision) information in numerical form, such as lpddr3-ff,0201 for an LPDDR3 part with manufacturer ID ff and revision ID 0201. This helps cases where LPDDR parts are probed at runtime by boot firmware and cannot be matched to hardcoded part numbers, such as the firmware on the qcom/sc7280-herobrine boards does (which supports 4 different memory configurations at the moment, and more are expected to be added later at a point where the boot firmware can no longer be updated to specifically accommodate them).

2022-10-18dt-bindings: memory: Factor out common properties of LPDDR bindingsJulius Werner
The bindings for different LPDDR versions mostly use the same kinds of properties, so in order to reduce duplication when we're adding support for more versions, this patch creates a new lpddr-props subschema that can be referenced by the others to define these common parts. (This will consider a few smaller I/O width and density numbers "legal" for LPDDR3 that are usually not used there, but this should be harmless.)
