The ARR (auto reload register) and CMP (compare) registers are successively written. The status bits to check the update of these registers are polled together with regmap_read_poll_timeout(). The condition to end the loop may become true, even if one of the register isn't correctly updated. So ensure both status bits are set before clearing them.

If the userspace daemon is killed in the middle of an invoke (e.g. audiopd listerner invoke), we need to skip the unmapping on device release, otherwise the DSP will crash.

In order to be able to start the adsp listener for audiopd using adsprpcd, we need to add the corresponding ioctl for creating a static process. On that ioctl call we need to allocate the heap. Allocating the heap needs to be happening only once and needs to be kept between different device open calls, so attach it to the channel context to make sure that remains until the RPMSG driver is removed. Then, if there are any VMIDs associated with the static ADSP process, do a call to SCM to assign it. And then, send all the necessary info related to heap to the DSP. Co-developed-by:

Now it is just used to protect device mode transitions (typically to and from buffered capture). Includes merge of an immutable i2c branch to get the new i2c_client_get_device_id() (thanks to Wolfram for providing the branch). Based on rc3 to pick up some precursor fixes from early in the cycle and avoid an unnecessarily messy history. New device support * adi,ad4310 - New driver to support this very flexible measurement device including a 24 bit ADC. Later fix for documentation build issue. * adi,adxl355 - Add support of the ADXL359 accelerometer. * adi,ltc2983 - Support additional variants of the temperatures sensor: LTC2984 with an EEPROM LTC2985, LTC2986 with only 10 channels. * invensense,icm42600 - Add support for icm42631 (needed only ID and WHOAMI) * kionix,kx022a - New driver for this 3 axis accelerometer. * maxim,max11401 - New driver to support this 24-bit 10 channel ADC. Includes some new ABI to support configuration of notch filters. * mediatek,mt6370 - Add new driver to support the ADC part of the mt6370. * st,lsm6dsx - Add support for LSM6DSV accelerometer and gyroscope. Simple additional of chip specific data and IDs. - Add support for LSM6DSV16X accelerometer and gyroscope. Compatible with features currently implemented for the LSM6DSV. * st,stm32-adc - Add support for stm32pm13x SoCs. core / subsystem wide: - Add new IIO_STATIC_CONST_DEVICE_ATTR() which is a dance necessary to allow for the wrapping of attributes in the code that duplicates them for multiple buffers. - Harden against future issues with expectation that all buffer attributes are iio_dev_attrs by changing the code to take an array of pointers of the correct type. - Last transitions of drivers to local locks rather than missuses of mlock. - Add an iio_device_claim_buffer_mode() callback to avoid a race in the max30100 driver without directly using mlock. - Move mlock to the opaque IIO device structure to prevent misuse. - Add missing spi_device_id tables to support auto loading of modules. - Update some ADI maintainers in DT bindings. - A few more moves of bus drivers and core module sets to export name spaces. - Extensive use of new devm_regulator_get_enable() and friends. - Switch a bunch of i2c drivers to probe_new() including the bmp280 which makes use of the new i2c_client_get_device_id() helper to simplify this change. dt-bindings: - More use of spi-peripheral-props.yaml. Features * freescale,mpl115 - Use runtime PM to implement shutdown GPIO support. * melexis,mlx90632 - More sophisticated runtime power management - Provide access to sampling frequency. - Trivial follow up fixes. * microchip,mcp3911 - Support control of PGA. * st,lsm6dsx - Add support for software triggers for cases where the IRQ lines are not wired up. * vishay,vcnl4000 - Add control of integration time.

The ADC block on the RZ/Five SoC is identical to one found on the RZ/G2UL SoC. "renesas,r9a07g043-adc" compatible string will be used on the RZ/Five SoC so to make this clear, update the comment to include RZ/Five SoC. No driver changes are required as generic compatible string "renesas,rzg2l-adc" will be used as a fallback on RZ/Five SoC. Signed-off-by:

Prior to commit bd5d54e4 ("iio: adc128s052: add ACPI _HID AANT1280"), the driver unconditionally used spi_get_device_id() to get the index into the adc128_config array. However, with that commit, OF-based boards now incorrectly treat all supported sensors as if they are an adc128s052, because all the .data members of the adc128_of_match table are implicitly 0. Our board, which has an adc122s021, thus exposes 8 channels whereas it really only has two. Fixes: bd5d54e4 ("iio: adc128s052: add ACPI _HID AANT1280") Signed-off-by:

Add smart calibration support for STM32MP1. - STM32MP15x: both linear & offset calibration are supported - STM32MP13x: Only offset calibration is supported Linear calibration: Linear calibration is SoC dependent and does not change over time so it can be done only once. Linear calibration may have already been done in u-boot. Skip calibration execution if calibration data are already available. Save calibration factors in private data and restore them from private data on next ADC start. Offset calibration: This calibration may vary over time, depending on temperature or voltage. Run offset single-ended and differential calibration on each ADC start, as it is not time consuming. This calibration do not need to be saved. So, remove calfact_s and calfact_d value and bitfields that are no longer used. Signed-off-by:

We have a board where the reset pin of the ad74412 is connected to a gpio, but also pulled low (i.e., asserted) by default. Hence to get the chip out of reset, the driver needs to know about that gpio and deassert the reset signal before attempting to communicate with the chip. When a reset-gpio is given in device tree, use that instead of the software reset. According to the data sheet, the two methods are functionally equivalent. Signed-off-by:
