2019-10-15dt-bindings: iio: adc: max1027: Mark interrupts as optionalMiquel Raynal1-0/+2
The chips have a 'start conversion' and a 'end of conversion' pair of pins. They can be used but this is absolutely not mandatory as regular polling is supported by the chip depending on its internal clocking setup. There is no physical reason to force the use of interrupts so turn them optional. Also, once the interrupt turned optional, these devices fit perfectly the "trivial devices" described in the generic (yaml) bindings file, so instead of converting this text file to json schema, we can just add the relevant compatibles in: Documentation/devicetree/bindings/trivial-devices.yaml.

2019-10-14dt-bindings: Clean-up regulator '-supply' schemasRob Herring5-12/+2
Regulator '*-supply' properties are always a single phandle, so 'maxItems: 1' or a $ref is not necessary. All that's needed is either 'true' or an optional 'description'. Following this clean-up, the meta-schema will enforce this pattern. There's one case in tree with 'innolux,n156bge-l21' having 2 phandles. This appears to be a mistake or abuse of simple-panel as it's 2 different voltage rails connected to 'power-supply'.

https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: First set of IIO new device support, cleanups and features for the 5.5 cycle Third version with the adis rework set dropped as better to just have a fresh version of that at some future date. The usual mixed backs of new device support being added to drivers, long term reworks continuing and little per driver cleanups and features. Also a few trivial counter subsystem tidy ups on behalf of William. Core new feature * Device label support. A long requested feature no one got around to implementing before. Allows DT based provision of a 'label' that identifies a device uniquely within a system. This differs from existing 'name' which is meant to be the part number. New device support * ingenic-adc - Support for the JZ4770 SoC ADC including bindings. * inv_mpu6050 - Add support for magnetometer in MPU925x parts. Fiddly to do as this is actually a separate device sitting inside the package, but with the master device being able to schedule reads etc. Will only run if the auxiliary bus is not in use for any other devices. Features * ad7192 - Userspace calibration controls to do zero and full scale. * st_lsm6dsx - Enable latched interrupts by default for sensors events with related clear. - Motion events and related wakeup source. This needed quite a bit of refactoring as well. Cleanups and minor features * ad7192 - sysfs ABI docs * ad7949 - Remove code to readback configuration word as driver never actually enabled it. - Fix incorrect xfer length. Not actually known to cause problems other than wasted bus usage. * adis16080 - Replace core mlock usage with local lock with more appropriate scope. * adis16130 - Remove pointless mlock usage. * adis16240 - Remove include of gpio.h as no gpio usage. * atlas-ph-sensor - Improve logical ordering of buffer predisable / postenable functions. This is part of a longer term rework Alexandru is driving towards. * bh1750 - Fix up a static compiler warning and make the code more readable. - yaml conversion of binding + MAINTAINERS entry. * bmp280 - Drop a stray newline. * cm36651 - Drop a redundant assignment * itg3200 - Alignment cleanup. * max31856 - Add missing of_node and parent references, useful to identify the device. * sc27xx_adc - Use devm_hwspin_lock_request_specific rather than local rolled version. * stm32-lptimer counter - kernel-doc warning. * stm32-timer counter - kernel-doc warning. - Alignment cleanup. * sx9500 - Improve logical ordering of buffer predisable / postenable functions.

The AD7192 binding describes two regulator properties, avdd-supply and dvdd-supply, but describes it as a constant string that must be avdd and dvdd. This is wrong since a *-supply property is actually a phandle, and results in warnings when the example is validated (or any device tree using that device, for that matter).

Pull ARM DT updates from Arnd Bergmann: "This is another huge branch with close to 450 changessets related to devicetree files, roughly half of this for 32-bit and 64-bit respectively. There are lots of cleanups and additional hardware support for platforms we already support based on SoCs from Renesas, ST-Microelectronics, Intel/Altera, Rockchips, Allwinner, Broadcom and other manufacturers. A total of 6 new SoCs and 37 new boards gets added this time, one more SoC will come in a follow-up branch. Most of the new boards are for 64-bit ARM SoCs, the others are typically for the 32-bit Cortex-A7. Going more into details for SoC platforms with new hardware support: - The Snapdragon 855 (SM8150) is Qualcomm's current high-end phone platform, usually paired with an external 5G modem. So far we only support the Qualcomm SM8150 MTP reference platform, but no actual products. - For the slightly older Qualcomm platforms, support for several interesting products is getting added: Three laptops based on Snapdragon 835/MSM8998 (Asus NovaGo, HP Envy X2 and Lenovo Miix 630), one laptop based on Snapdragon 850/sdm850 (Lenovo Yoga C630) and several phones based on the older Snapdragon 410/MSM8916 (Samsung A3 and A5, Longcheer L8150 aka Android One 2nd gen "seed" aka Wileyfox Swift). - Mediatek MT7629 is a new wireless network router chip, similar to the older MT7623. It gets added together with the reference board implementation. - Allwinner V3 is a repackaged version of the existing low-end V3s chip, and is used in the tiny Lichee Pi Zero plus, also added here. There is also a new TV set-top box based on Allwinner H6, the Tanix TX6, and the eMMC variant of the Olimex A64-Olinuxino development board. - NXP i.MX8M Nano is a new member of the ever-expanding i.MX SoC family, similar to the i.MX8M Mini. As usual, there is a large number of new boards for i.MX SoCs: Einfochips i.MX8QXP AI_ML, SolidRun Hummingboard Pulse baseboard and System-on-Module, Boundary Devices i.MX8MQ Nitrogen8M, and TechNexion PICO-PI-IMX8M-DEV for the 64-bit i.MX8 line. For 32-bit, we get the Kontron i.MX6UL N6310 SoM with two baseboards, the PHYTEC phyBOARD-Segin SoM with three baseboards, and the Zodiac Inflight Innovations i.MX7 RMU2 board. - In a different NXP product line, the Layerscape LS1046A "Freeway" reference board gets added. - Amlogic SM1 (S905X3) and G12B (S922X, A311D) are updated chips from their set-top-box line and smart speaker with newer CPU and GPU cores compared to their predecessors. Both are now also supported by the Khadas VIM3 development board series, and the dts files for that get reorganized a bit to better deal with all variants. Another board based on SM1 that gets added is the SEI Robotics SEI610. - There are a handful of new x86 and Power9 server boards using Aspeed BMC chips that are gaining support for running Linux on the BMC through the OpenBMC project: Facebook Minipack/Wedge100/Wedge40, Lenovo Hr855xg2, and Mihawk. Notably these are still new machines using SoCs based on the ARM9 and ARM11 CPU cores, as support for the new Cortex-A7 based AST2600 is still ramping up. - There are three new end-user products using 32-bit Rockchips SoCs: Mecer Xtreme Mini S6 is an Android "mini PC" box based on the low-end RK3229 chip, while the two AOpen products Chromebox Mini (Fievel) and Chromebase Mini (Tiger) run ChromeOS and are meant for commercial settings(digital signage, PoS, ...). - One more single-board computer based on the popular 64-bit RK3399 is added: the Leez RK3399 P710" * tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (467 commits) arm64: dts: qcom: Add Lenovo Yoga C630 ARM: dts: aspeed-g5: Fixe gpio-ranges upper limit ARM; dts: aspeed: mihawk: File should not be executable ARM: dts: aspeed: swift: Change power supplies to version 2 ARM: dts: aspeed: vesnin: Add secondary SPI flash chip ARM: dts: aspeed: vesnin: Add wdt2 with alt-boot option ARM: dts: aspeed-g4: Add all flash chips ARM: dts: exynos: Enable GPU/Mali T604 on Arndale board ARM: dts: exynos: Enable GPU/Mali T604 on Chromebook Snow ARM: dts: exynos: Add GPU/Mali T604 node to Exynos5250 ARM: dts: exynos: Fix min/max buck4 for GPU on Arndale board ARM: dts: exynos: Mark LDO10 as always-on on Peach Pit/Pi Chromebooks ARM: dts: exynos: Remove not accurate secondary ADC compatible arm64: dts: rockchip: limit clock rate of MMC controllers for RK3328 arm64: dts: meson-sm1-sei610: add stdout-path property back arm64: dts: meson-sm1-sei610: enable DVFS arm64: dts: khadas-vim3: add support for the SM1 based VIM3L dt-bindings: arm: amlogic: add Amlogic SM1 based Khadas VIM3L bindings arm64: dts: khadas-vim3: move common nodes into meson-khadas-vim3.dtsi arm64: dts: meson: g12a: add reset to tdm formatters ...

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: First set of new device support, features and cleanups for IIO in the 5.3 cycle New device support * mt6577 - add supprot for the mt6765 which requires a few minor additional new features in the driver. Yaml binding conversions * adxl345 * isl29018 * tsl2583 * tsl2772 Minor features and improvements * ad5758 - declare an of_device_id table rather than just relying on the spi fallback which doesn't use the manufacturer id. - drop a set but not used variable left from previous refactor. * ad7816 - Add a bit more description to kconfig text. * ad9523 - change calculation order to improve frequency accuracy. * adxl372 - declare an of_device_id table * adt7316 - white space. * at91_adc - Use dev_get_drvdata directly rather than boucing to the platform device and back again. * cros_ec - add an id sysfs entry to bring in line with the other implementations. * ds5522 - drop a check on the of_node existing as we don't actually use it for anything. * kxsd9 - declare an of_device_id table. * maxim_thermocouple - declare an of_device_id table. * mt6577 - add dt binding entry for mt8183 which is also supported. * rcar-gyroadc - tidy up unnecessary error messages. * stm32-dfsdm - improved error handling. * stmpe-adc - drop an unnecessary variable assignment. - add an of_device_id table. - reinit completion on begin converstion to avoid a path in which previous round had been interrupted, also switch to non interruptible wait to avoid an issue with a user program using -pg - simplify interrupt handling by just having them always enabled. - reset all interrupts on startup and in the timeout handler to avoid getting stuck. * sun4i-gpadc - SPDX * tag 'iio-for-5.3a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (28 commits) iio: adc: mediatek: mt6577-auxadc, add mt6765 support dt-bindings: iio: adc: mediatek: Add document for mt6765 dt-bindings: iio: accel: adxl345: switch to YAML bindings iio: adc: sun4i-gpadc-iio convert to SPDX license tags iio: ad9523-1: Improve reported VCO frequency accuracy iio: dac: ds4422/ds4424 drop of_node check iio: stmpe-adc: Reset possible interrupts iio: stmpe-adc: Use wait_for_completion_timeout iio: stmpe-adc: Enable all stmpe-adc interrupts just once iio: stmpe-adc: Reinit completion struct on begin conversion iio: stmpe-adc: Add compatible name iio: stmpe-adc: Remove unnecessary assignment staging: iio: adc: Add paragraph to describe Kconfig symbol staging: iio: adt7316: match parenthesis alignment iio: adc: rcar-gyroadc: Remove devm_iio_device_alloc() error printing dt-bindings: iio: isl29018: convert bindings to YAML format dt-bindings: adc: mt8183: add binding document iio: dac: ad5758: remove set but not used variable 'dc_dc_mode' iio: cros_ec: add 'id' sysfs entry iio: adc: stm32-dfsdm: missing error case during probe ...
