| * iio: imu: inv_mpu6050: fix interrupt status read for old buggy chipsJean-Baptiste Maneyrol2024-08-171-2/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Interrupt status read seems to be broken on some old MPU-6050 like chips. Fix by reverting to previous driver behavior bypassing interrupt status read. This is working because these chips are not supporting WoM and data ready is the only interrupt source.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cfg pointer is set before reading the channel number that the configuration should point to. This causes configurations to be shifted by one channel. For example setting bipolar to the first channel defined in the DT will cause bipolar mode to be active on the second defined channel. Fix by moving the cfg pointer setting after reading the channel number.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | With commit 7b0c9f8fa3d2 ("iio: adc: ad_sigma_delta: Add optional irq selection"), we can get the irq line from struct ad_sigma_delta_info instead of the spi device.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ad7124_find_similar_live_cfg() computes the compare size by substracting the address of the cfg struct from the address of the live field. Because the live field is the first field in the struct, the result is 0. Also, the memcmp() call is made from the start of the cfg struct, which includes the live and cfg_slot fields, which are not relevant for the comparison. Fix by grouping the relevant fields with struct_group() and use the size of the group to compute the compare size; make the memcmp() call from the address of the group.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ad7124_soft_reset() function has the assumption that the chip will assert the "power-on reset" bit in the STATUS register after a software reset without any delay. The POR bit =0 is used to check if the chip initialization is done. A chip ID mismatch probe error appears intermittently when the probe continues too soon and the ID register does not contain the expected value.

| * iio: adc: ad7606: remove frstdata check for serial modeGuillaume Stols2024-07-293-29/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current implementation attempts to recover from an eventual glitch in the clock by checking frstdata state after reading the first channel's sample: If frstdata is low, it will reset the chip and return -EIO. This will only work in parallel mode, where frstdata pin is set low after the 2nd sample read starts. For the serial mode, according to the datasheet, "The FRSTDATA output returns to a logic low following the 16th SCLK falling edge.", thus after the Xth pulse, X being the number of bits in a sample, the check will always be true, and the driver will not work at all in serial mode if frstdata(optional) is defined in the devicetree as it will reset the chip, and return -EIO every time read_sample is called. Hence, this check must be removed for serial mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the AXP717 ADC. The AXP717 differs from other ADCs in this series by utilizing a 14 bit ADC for all channels (a full 16 bits with the first 2 digits reserved). It also differs by lacking a battery discharge current channel. Note that while the current charge channel itself is included in this driver for the AXP717 and listed in the datasheet, no scale or offset was given for this channel. For now no scale or offset is provided in this driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a frequent minor comment in reviews, so start cleaning up existing drivers in the hope we get fewer cases of cut and paste. There are not kernel wide rules for these, but for IIO the style that I prefer (and hence most common) is: - Space after { and before } - No comma after terminator { } This may cause merge conflicts but they should be trivial to resolve hence I have not broken this into per driver patches.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The vendorless compatible strings are deprecated and weren't retained when the binding was converted to schema. As a result, they are listed as undocumented when running "make dt_compatible_check". Rather than add them back to the schema, let's just drop them as they are unnecessary.

Add automatic mode switching between the UVS and ALS channel based on which channel is being accessed. The default mode in which the sensor start is ALS mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This implements buffered reads for the ad4695 driver using the typical triggered buffer implementation, including adding a soft timestamp channel. The chip has 4 different modes for doing conversions. The driver is using the advanced sequencer mode since that is the only mode that allows individual configuration of all aspects each channel (e.g. bipolar config currently and oversampling to be added in the future).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add scaling support to STM32 DFSDM. When used in an analog context, a DFSDM filter typically converts the data from a sigma delta modulator. The IIO device associated to the DFSDM filter provides these data as raw data. The IIO device can provide scaling information (voltage and offset) to allow conversion of raw data into physical values. With the new binding based on IIO backend framework, the sigma delta modulators are defined as backends providing scaling information. The scaling is not supported with legacy binding.
