dt-bindings: Remove 'Device Tree Bindings' from end of title:

2022-08-25T19:06:57Z

As indicated in link: https://lore.kernel.org/all/20220822204945.GA808626-robh@kernel.org/ DT schema files should not have 'Device Tree Binding' as part of there title: line. Remove this in most .yaml files, so hopefully preventing developers copying it into new .yaml files, and being asked to remove it.

dt-bindings: bus: qcom,ssc-block-bus: rework arrays and drop redundant minItems

2022-07-18T20:24:55Z

There is no need to specify "minItems" if it equals to "maxItems". On the other hand number of items in an array can be specified via describing items, which might bring some additional information. This simplifies a bit the binding. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Rob Herring Link: https://lore.kernel.org/r/20220712154602.26994-1-krzysztof.kozlowski@linaro.org

Merge tag 'qcom-drivers-for-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/drivers

2022-05-09T21:14:06Z

Qualcomm driver updates for v5.19 This converts a wide range of Qualcomm-related DeviceTree bindings to YAML, in order to improve our ability to validate the DeviceTree source. The RPMh power-domain driver gains support for the modem platform SDX65, the compute platform SC8280XP and the automotive platform SA8540p. While LLCC gains support for SC8180X and SC8280XP and gains a MODULE_DEVICE_TABLE() to make it functional as a module. It adds a driver for configuring the SSC bus, providing Linux access to the hardware blocks in the sensor subsystem. The socinfo driver gets confusion related to MSM8974 Pro sorted out and adds new ids for SM8540 and SC7280. The SCM driver gains support for MSM8974. Add missing of_node_put() in smp2p and smsm drivers. Stop using iterator after list_for_each_entry() and define static definitions as such, in the PDR driver. * tag 'qcom-drivers-for-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (33 commits) soc: qcom: pdr: use static for servreg_* variables soc: qcom: llcc: Add sc8180x and sc8280xp configurations dt-bindings: arm: msm: Add sc8180x and sc8280xp LLCC compatibles soc: qcom: rpmhpd: add sc8280xp & sa8540p rpmh power-domains soc: qcom: rpmhpd: Don't warn about sparse rpmhpd arrays dt-bindings: power: rpmpd: Add sc8280xp RPMh power-domains spi: dt-bindings: qcom,spi-geni-qcom: convert to dtschema soc: qcom: socinfo: Sort out 8974PRO names dt-bindings: soc: qcom,smp2p: convert to dtschema dt-bindings: qcom: geni-se: Update UART schema reference dt-bindings: qcom: geni-se: Update I2C schema reference dt-bindings: soc: qcom,rpmh-rsc: convert to dtschema bus: add driver for initializing the SSC bus on (some) qcom SoCs dt-bindings: bus: add device tree bindings for qcom,ssc-block-bus dt-bindings: qcom: qcom,geni-se: refer to dtschema for SPI dt-bindings: soc: qcom,smd: convert to dtschema firmware: qcom_scm: Add compatible for MSM8976 SoC dt-bindings: firmware: qcom-scm: Document msm8976 bindings soc: qcom: smem: validate fields of shared structures soc: qcom: smem: map only partitions used by local HOST ...

dt-bindings: bus: add device tree bindings for qcom,ssc-block-bus

2022-04-19T17:02:04Z

Adds bindings for the AHB bus which exposes the SSC block in the global address space. This bus (and the SSC block itself) is present on certain qcom SoCs. In typical configuration, this bus (as some of the clocks and registers that we need to manipulate) is not accessible to the OS, and the resources on this bus are indirectly accessed by communicating with a hexagon CPU core residing in the SSC block. In this configuration, the hypervisor is the one performing the bus initialization for the purposes of bringing the haxagon CPU core out of reset. However, it is possible to change the configuration, in which case this binding serves to allow the OS to initialize the bus.

dt-bindings: Fix 'enum' lists with duplicate entries

2022-04-04T19:20:09Z

There's no reason to list the same value twice in an 'enum'. Fix all the occurrences in the tree. A meta-schema change will catch future ones.

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.

dt-bindings: Improve phandle-array schemas

2022-02-04T15:43:42Z

The 'phandle-array' type is a bit ambiguous. It can be either just an array of phandles or an array of phandles plus args. Many schemas for phandle-array properties aren't clear in the schema which case applies though the description usually describes it. The array of phandles case boils down to needing: items: maxItems: 1 The phandle plus args cases should typically take this form: items: - items: - description: A phandle - description: 1st arg cell - description: 2nd arg cell With this change, some examples need updating so that the bracketing of property values matches the schema.
