Required fairly substantial rework to allow for small differences between this an existing parts.* bma400 accelerometer - New driver with follow up patch for regulator support. - DT bindings.* asc dlhl60d - New driver support this range of pressure and temperature sensors. - DT bindings.* ltc2496 ADC - New driver to support this ADC. - Split the existing LTC2497 driver generic component out and reuse. - DT bindings.* parallax ping - New driver supporting ultrasonic and laser tof distance sensors. - Bindings for these sensors.New features* core - New char type for read_raw returns, used for thermocouple types. - Rename read_first_n callback to read. The reasons behind the original naming are lost to the mists of time.* ad799x - Allow pm_ops to disable device completely allowing regulator power down.* bma180 - Enable basic regulator support.* dmaengine buffer - Report platform data alignment requirements via new ABI.* max31856 - Add option to set mains filter rejection frequency and document new in_temp_filter_notch_center_frequency ABI. - Add support for configuring HW averaging (oversampling ratio) - Add runtime configuration of thermocouple type and document new ABI.* maxim-thermocouple - Add read only access to thermocouple type using new ABI, includes adding more specific compatibles to reflect which variant of the chip is being used.* mpu6050 - Provide option to support the PMU9150 in package magnetometer directly rather than via auxiliary bus.* stm32_adc - Add overrun interrupt checks to detect if this happens.* st_lsm6dsx - Enable the sensor-hub support for lsm6dsm. Includes various reworks to allow this.Cleanups and minor fixes* Subsystem wide - Tidy up indentation in Kconfig and fix alphabetical order of AD7091R5. - Drop linux/gpio.h and linux/of_gpio.h from drivers that don't use them.* ad7266 - Convert to GPIO descriptors.* ad7303 - Avoid a dance with checking if the regulator is supplied by just using the optional request interface.* ad7887 - Simplify channel specification assignment to enable adding more devices.* ad7923 - Drop some unused and largely pointless defines of BOB_N==N variety. - Tidy up checkpatch warnings. - Add missing of_device_id table.* adf4350 - Convert to GPIO descriptors.* ak8975 - Convert to GPIO descriptors.* ADIS library and drivers - Expand scope of txrx_lock to cover all state and rename as state_lock - Add unlocked read / write to allow grouping of consecutive calls under single lock / unlock. - Add unlocked check_status, reset to allow grouping under single lock / unlock. - Remove remaining uses of core mlock for local state protection. mlock should never be used directly as it protects tightly defined core IIO device management state.* adis16240 - Enforce only supported SPI mode on driver load + add DT binding doc.* atlas-ph-sensor - Rename to atlas-sensor given it now covers things beyond ph sensors.* bma180 - Use local dev variable to tidy up code. - Use c99 style explicity .member assignment to make driver more readable.* bmp280 - Drop ACPI support. No evidence this was used and appropriate ID is not registered. - Allow ACPI to bind device via PRP0001* dmaengine buffer - Use dma_request_chan instead of dma_request_slave_channel_reason as that ABI is going away. - Add module info to avoid tainting the kernel.* hts221 - Avoid magic number defines when only used to fill structure elements that are self describing.* lm3533 - Drop a stray semicolon.* max9611 - Cleanup enum handling to be more resilient to future changes.* mpu6050 - Delete MPU9150 from supported SPI devices as doesn't provide SPI. - Select I2C_MUX again after kbuild issue fixed elsewhere.* stm32-timer - Drop an unnecessary register update.* ssp_sensors - Convert to GPIO descriptors.* st_sensors - drop !CONFIG_ACPI defines as ACPI_PTR() will stop them being used anyway. - Make default platform data structures __maybe_unsued. - Fill in some missing kernel-doc function parameters.* st_lsm6dsx - white space fixes. - Mark some constants that aren't always used as __maybe_unused. - Drop of ID table guards as they just pervent use under ACPI. - Switch to device properties to allow ACPI usage.* st_uvis25 - Drop acpi.h include as no ACPI APIs used.* ti-ads1015 - Drop legacy platform data as no one seems to be using it. - Use the device property API instead of OF specific.* ti-ads7950 - typo fix in error message.* tag 'iio-for-5.6a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (99 commits) iio: accel: bma180: BMA254 support iio: pressure: bmp280: Allow device to be enumerated from ACPI iio: pressure: bmp280: Drop ACPI support dt-bindings: iio: adc: convert sd modulator to json-schema iio: buffer: rename 'read_first_n' callback to 'read' iio: buffer-dmaengine: Report buffer length requirements bindings: iio: pressure: Add documentation for dlh driver dt-bindings: Add asc vendor iio: pressure: Add driver for DLH pressure sensors iio: buffer-dmaengine: Add module information iio: accel: bma180: Use explicit member assignment iio: accel: bma180: Basic regulator support iio: accel: bma180: Add dev helper variable iio: imu: st_lsm6dsx: enable sensor-hub support for lsm6dsm iio: imu: st_lsm6dsx: rename st_lsm6dsx_shub_read_reg in st_lsm6dsx_shub_read_output iio: imu: st_lsm6dsx: check if shub_output reg is located in primary page iio: imu: st_lsm6dsx: check if pull_up is located in primary page iio: imu: st_lsm6dsx: check if master_enable is located in primary page iio: imu: st_lsm6dsx: export max num of slave devices in st_lsm6dsx_shub_settings iio: light: remove unneeded semicolon ...

4538c185680996d7328beac629dbdb7dd3f8f34e - iio: buffer-dmaengine: Report buffer length requirements

Wed, 11 Dec 2019 12:56:15 +0100

iio: buffer-dmaengine: Report buffer length requirementsThe dmaengine buffer has some length alignment requirements that can differfrom platform to platform. If the length alignment requirements are not metunexpected behavior like dropping of samples can occur.Currently these requirements are not reported and applications need to knowthe requirements of the platform by some out-of-band means.Add a new buffer attribute that reports the length alignment requirementscalled `length_align_bytes`. The reported length alignment is in bytes thatmeans the buffer length alignment in sample sets depends on the number ofenabled channels and the bytes per channel. Applications using thisattribute to determine the buffer size requirements need to consider this.Signed-off-by: Lars-Peter Clausen Signed-off-by: Alexandru Ardelean Signed-off-by: Jonathan Cameron List of files: /linux/Documentation/ABI/testing/sysfs-bus-iio-dma-buffer
