https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Second set of IIO + counter new device support, features etc for the 5.5 cycle. Note two merge commits in here, both for immutable branches based of 5.4-rc1. 1. Ti eqep driver because of some file moves in precursor patches. I suspect no one else will pull this one. 2. ab8500 refactor as changes in power supply, hwmon and mfd trees. This may come via numerous trees as well as IIO. Counter subsystem related * ti eqep - New device support with bindings. - Includes prior file move to reflect more general use of ti-pwmss. * Counter core - simplify count_read and count_write callbacks + document change. - fix a typo in docs. Various subsystems related * AB8500 - ab8500_btemp driver converted to be an IIO consumer driver. - ab8500_charger driver converted to be an IIO consumer driver. - ab8500_fg fuel gauge driver converted to be an IIO consumer driver. - ab8500 hwmon driver converted to be an IIO consumer driver. - mfd bindings augmented with the adc channels to make the above work. - drop original mfd driver. New device support * ab8500 - new ADC driver used by the above other subystems via the IIO consumer interface. * adux1020 photometric sensor - new driver and dt bindings. * fxos877cq - new driver for this simple(ish) IMU with DT bindings. * intel_mrfld_adc - new driver for the ADC found on Intel Merrifield platforms. * ltc2983 - new driver for this multi-sensor type temperature interface. Includes complex DT bindings. * max1027 - support for 12 bit devices, max1227, max1229 and max1231 + add to trivial bindings. * st_lsm6dsx - support for the LSM6DS0 6 axis MEMs sensor. Note different from the LSM6DSO which the driver already supports *sigh* - support for the LSM6DSRX 6 axis MEMs sensor. Features and cleanups * ad7303 - replace use of core mlock with a local lock with cleanly defined scope. * ad9834 - add a check for devm_clk_get failing. * at91-sama5d2 - tidy up a 0 as NULL warning. * bmp280 - endian type tidy ups. - use bulk regulator ops for a small reduction in code. - use devm_add_action... to simplify error path handling. * exynos - drop stray semicolon. - use devm_platform_ioremap_resource to reduce boilerplate. * hx711 - various tricks to improve the frequency of read out possible. * max1027 - debugfs support. - make interrupts optional. - reset at probe to get clean state. - refactors to allow addition of new device support. * maxim thermocouple - drop an unneeded semicolon. * mb1232 - yaml binding conversion. * mcp320x - tidy up an endian types in cast warning. * meson_saradc - use devm_platform_ioremap_resource to reduce boilerplate. * mpu3050 - make a poison value explicity big endian to supress a warning. * pulsedlight v2 - endian type tidy ups. * sgp30 - drop an excess semicolon. * sps30 - make truncation explicit with masking to clean up a warning. * st sensors - drop gpio include as none of these support gpios. * st_lsm6dsx - tidy up some alignment issues. - refactors to allow addition of new device support. * allow varients of irq related reg definitions. * avoid accessing active-low, open-drain regs if not provided. * allow varients of bdu/boot and reset regs. * allow for enabling or disabling wakeup sources through platform data (seems someone still uses this). - enable wake-up events for LSM6DS0 - use the drdy mask to avoid some invalid samples during initial start of sensor. - Add support to trim the timestamp. * stm32_adc - kernel-doc fixes. * stm32_dac - power management support. * stmpe-adc - Fix endian type of local variable. * twl4030 - use false / true instead of 0 / 1 for booleans. * xilinx-xadc - use devm_platform_ioremap_resouce to reduce boilerplate. * zpa2326 - reorganise buffer handling setup to be more consistent. Fixes (mostly recent additions) * cpcap-adc - Fix mising IRQF_ONESHOT that would cause warnings to be printed. * st_lsm6dsx - Sanity check the read_fifo pointer is set. - use locked read and update functions to prevent some races. - avoid accessing enable_reg if not provided. - take a lock to prevent a race in updating the config. - kernel-doc fixes. - document wakeup-source property in dt binding. - fix lsm9ds1 gyro gain definitions. * tag 'iio-for-5.5b' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (73 commits) dt-bindings: iio: imu: st_lsm6dsx: add lsm6dsrx device bindings iio: imu: st_lsm6dsx: add support to LSM6DSRX iio: st: Drop GPIO include iio: adc: hx711: optimize performance in read cycle iio: adc: stm32-adc: fix kernel-doc warnings iio: pressure: zpa2326: fix iio_triggered_buffer_postenable position iio: chemical: sgp30: drop excess semicolon iio: adc: twl4030: Use false / true instead of 0 / 1 with booleans dt-bindings: iio: Add ltc2983 documentation iio: temperature: Add support for LTC2983 iio: pressure: bmp280: use devm action and remove labels from probe iio: pressure: bmp280: use bulk regulator ops iio: imu: Add support for the FXOS8700 IMU dt-bindings: iio: imu: add fxos8700 imu binding staging: iio: ad9834: add a check for devm_clk_get iio: adc: xilinx-xadc: use devm_platform_ioremap_resource iio: temp: maxim thermocouple: Drop unneeded semi colon. iio: adc: cpcap-adc: Fix missing IRQF_ONESHOT as only threaded handler. iio: adc: meson_saradc: use devm_platform_ioremap_resource iio: adc: exynos: use devm_platform_ioremap_resource ...

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.

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. This is part of a longer term rework Alexandru is driving towards. * tcs3414 - Improve logical ordering of buffer predisable / postenable functions.
