2022-04-04dt-bindings: Fix incomplete if/then/else schemasRob Herring1-17/+17
A recent review highlighted that the json-schema meta-schema allows any combination of if/then/else schema keywords even though if, then or else by themselves makes little sense. With an added meta-schema to only allow valid combinations, there's a handful of schemas found which need fixing in a variety of ways. Incorrect indentation is the most common issue.

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.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi Pull spi updates from Mark Brown: "The overwhelming bulk of this pull request is a change from Uwe Kleine-König which changes the return type of the remove() function to void as part of some wider work he's doing to do this for all bus types, causing updates to most SPI device drivers. The branch with that on has been cross merged with a couple of other trees which added new SPI drivers this cycle, I'm not expecting any build issues resulting from the change. Otherwise it's been a relatively quiet release with some new device support, a few minor features and the welcome completion of the conversion of the subsystem to use GPIO descriptors rather than numbers: - Change return type of remove() to void. - Completion of the conversion of SPI controller drivers to use GPIO descriptors rather than numbers. - Quite a few DT schema conversions. - Support for multiple SPI devices on a bus in ACPI systems. - Big overhaul of the PXA2xx SPI driver. - Support for AMD AMDI0062, Intel Raptor Lake, Mediatek MT7986 and MT8186, nVidia Tegra210 and Tegra234, Renesas RZ/V2L, Tesla FSD and Sunplus SP7021" [ And this is obviously where that spi change that snuck into the regulator tree _should_ have been :^] * tag 'spi-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (124 commits) spi: fsi: Implement a timeout for polling status spi: Fix erroneous sgs value with min_t() spi: tegra20: Use of_device_get_match_data() spi: mediatek: add ipm design support for MT7986 spi: Add compatible for MT7986 spi: sun4i: fix typos in comments spi: mediatek: support tick_delay without enhance_timing spi: Update clock-names property for arm pl022 spi: rockchip-sfc: fix platform_get_irq.cocci warning spi: s3c64xx: Add spi port configuration for Tesla FSD SoC spi: dt-bindings: samsung: Add fsd spi compatible spi: topcliff-pch: Prevent usage of potentially stale DMA device spi: tegra210-quad: combined sequence mode spi: tegra210-quad: add acpi support spi: npcm-fiu: Fix typo ("npxm") spi: Fix Tegra QSPI example spi: qup: replace spin_lock_irqsave by spin_lock in hard IRQ spi: cadence: fix platform_get_irq.cocci warning spi: Update NXP Flexspi maintainer details dt-bindings: mfd: maxim,max77802: Convert to dtschema ...

2022-02-04dt-bindings: Improve phandle-array schemasRob Herring2-1/+3
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.

2021-11-05mfd: max77686: Do not enforce (incorrect) interrupt trigger typeKrzysztof Kozlowski1-1/+1
Interrupt line can be configured on different hardware in different way, even inverted. Therefore driver should not enforce specific trigger type - edge falling - but instead rely on Devicetree to configure it. The Maxim 77686 datasheet describes the interrupt line as active low with a requirement of acknowledge from the CPU therefore the edge falling is not correct. The interrupt line is shared between PMIC and RTC driver, so using level sensitive interrupt is here especially important to avoid races. With an edge configuration in case if first PMIC signals interrupt followed shortly after by the RTC, the interrupt might not be yet cleared/acked thus the second one would not be noticed.

dtschema" from Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com>: Hi All, Changes since v2 ================ 1. Add Stephen's and Rob's tags. 2. Correct inb-supply description in patch 10/10. Changes since v2 ================ 1. Add Rob's tags. 2. Remove "regulator-name" from properties (all regulator dtschema). 3. Move "unevaluatedProperties" higher to make code easier to read (all regulator dtschema). 4. Add ref-type to op-mode property (patch 6: s5m8767 regulators). Changes since v1 ================ 1. Drop DTS patches - applied. 2. Fully remove bindings/regulator/samsung,s5m8767.txt . 3. Minor subject reformatting and few typos in text. Intro ===== This patchset converts all devicetree bindings of Samsung S2M and S5M PMIC devices from txt to dtschema. It includes also two fixes because later conversion depends on it (contextually). Merging/dependencies ==================== 1. Regulator related binding changes depend on first two commits (the fixes), because of context. 2. The mfd bindings depend on clock and regulator bindings. The fixes and bindings changes (patches 1-10) should go via the same tree. For example regulator or mfd tree. Another alternative is that regulator patches (1-2, 4-6) go via Mark who later gives MFD a stable branch/tag to pull. Then the clock and MFD bindings would go on top via MFD tree. Or any other setup you would like to have. Overview of devices =================== Essentially all Samsung S2M and S5M PMICs are very similar devices. They provide the same functionality: regulators, RTC, 2 or 3 clocks and main power management (e.g. power cut to SoC). The differences are mostly in registers layout and number of regulators. The drivers are built around one common part, mfd/sec-core.c, and share some drivers between devices: 1. MFD sec-core for all devices, 1. one clock driver for most of devices, 2. one RTC driver for all devices, 3. three regulator drivers. The regulator drivers were implementing slightly different features, therefore one regulator binding for all devices does not make much sense. However the clock device binding can be shared. The final dtschema bindings try to implement this - share only the clock bindings.

2021-10-08regulator: s5m8767: do not use reset value as DVS voltage if GPIO DVS is ↵Krzysztof Kozlowski1-13/+8
disabled The driver and its bindings, before commit 04f9f068a619 ("regulator: s5m8767: Modify parsing method of the voltage table of buck2/3/4") were requiring to provide at least one safe/default voltage for DVS registers if DVS GPIO is not being enabled. IOW, if s5m8767,pmic-buck2-uses-gpio-dvs is missing, the s5m8767,pmic-buck2-dvs-voltage should still be present and contain one voltage. This requirement was coming from driver behavior matching this condition (none of DVS GPIO is enabled): it was always initializing the DVS selector pins to 0 and keeping the DVS enable setting at reset value (enabled). Therefore if none of DVS GPIO is enabled in devicetree, driver was configuring the first DVS voltage for buck[234]. Mentioned commit 04f9f068a619 ("regulator: s5m8767: Modify parsing method of the voltage table of buck2/3/4") broke it because DVS voltage won't be parsed from devicetree if DVS GPIO is not enabled. After the change, driver will configure bucks to use the register reset value as voltage which might have unpleasant effects. Fix this by relaxing the bindings constrain: if DVS GPIO is not enabled in devicetree (therefore DVS voltage is also not parsed), explicitly disable it.
