bmi150-accel and bmi323-imu are declared in an almost identical way in the ACPI and in some devices such as the Asus RC71L the "ROTM" property can be found: parse and use the ACPI-defined mount-matrix. Co-developed-by:

The Makefile for IIO ADC drivers is intended to be sorted alphabetically. I can be tricky to keep it sorted when adding new drivers when not all of the existing drivers are sorted. So let's sort everything now to make it easier to keep it sorted in the future. Signed-off-by:

After model data and num_hw_channles introduction, we have: ad3552r_desc, num_ch: used to keep channel number set in fdt, ad35xxr_model_data, num_hw_channels: for max channel checks, AD3552R_NUM_CH: just actually used to define the max array size on allocated arrays.

Add a "model data" structure to keep useful hardware-related information as from datasheet, avoiding id-based conditional choices later on. Removed id-based checks and filled model-specific structures with device specific features, In particular, num_hw_channels is introduced to keep the number of hardware implemented channels, since 1-channel versions of the DACs are added in this same patchset.

The adi,gain-scaling-p/n values are an inverted log2, so initial naming was set correctly, but the driver uses just adi,gain-scaling-p/n, and if fdt is created accordingly with the fdt bindings documentation, driver fails the probe. Observing that: - the Linux driver is the only consumer, - there are no upstreamed dts nodes related to ad3552r, the fix to the documentation side is preferred and less-risk.

Make sure we use a DMA safe buffer (IIO_DMA_MINALIGN) for all the spi transfers. Only relevant for writes since for reads spi_write_then_read() is used which does not require DMA safe buffers. Also note that for consistency, ad9467_spi_read() is also taking struct ad9467_state as a parameter (even if not really needed).

Unlike the other AD719Xs, AD7194 has configurable channels. The user can dynamically configure them in the devicetree. Add sigma_delta_info member to chip_info structure. Since AD7194 is the only chip that has no channel sequencer, num_slots should remain undefined. Also modify config AD7192 description for better scaling. Signed-off-by:

Devices that have both single-ended channels and differential channels cause a bit of confusion when the channels are configured in the devicetree. Clarify difference between these two types of channels for such devices by adding single-channel property alongside diff-channels. They should be mutually exclusive. Devices that have only single-ended channels can still use reg property to reference a channel like before. Suggested-by:

Replace custom attribute filter_low_pass_3db_frequency_available with standard attribute. Store the available values in ad7192_state struct. The function that used to compute those values replaced by ad7192_update_filter_freq_avail(). Function ad7192_show_filter_avail() is no longer needed. Note that the initial available values are hardcoded. Also moved the mutex lock and unlock in order to protect the whole switch statement since each branch modifies the state of the device.

For BMP18x, BMP28x, BME280, BMP38x the reading of the pressure value requires an update of the t_fine variable which happens through reading the temperature value. So all the bmpxxx_read_press() functions of the above sensors are internally calling the equivalent bmpxxx_read_temp() function in order to update the t_fine value. By just looking at the code this functionality is a bit hidden and is not easy to understand why those channels are not independent. This commit tries to clear these things a bit by splitting the bmpxxx_{read/compensate}_{temp/press/humid}() to the following: i. bmpxxx_read_{temp/press/humid}_adc(): read the raw value from the sensor. ii. bmpxx_calc_t_fine(): calculate the t_fine variable. iii. bmpxxx_get_t_fine(): get the t_fine variable. iv. bmpxxx_compensate_{temp/press/humid}(): compensate the adc values and return the calculated value. v. bmpxxx_read_{temp/press/humid}(): combine calls of the aforementioned functions to return the requested value.

The raw sensor data that have not been compensated yet cannot be signed values, so use unsigned ones. Also, compensated pressure values cannot be negative so use unsigned also there. Also, drop redundant cast of data->t_fine variable from s32 to s32. Signed-off-by:

These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own. While add it, also remove commas after the sentinel entries. Signed-off-by:

The bmp180_measure() function essentially waits for the end of the current conversion in order to read the values from the sensors. The name bmp180_measure() could be misinterpreted because it could be translated as "measure sensor values" even though it was probably trying to say "measure time for eoc". Give a more intuitive name to this function to be less confusing. Signed-off-by:

The iio_gts helpers build available times and scales tables based on the times and gains arrays given from the driver. The driver should be able to list all valid register values so that conversion from register valu to correct gain/time works for all supported register values. It might be more convenient for drivers to list these times and gains in the order where they're listed in the data-sheet than ascending order. However, for user who requests the supported scales / times it is more convenient to get the results in asscending order. Also, listing duplicated values is not meaning for the user. Hence the GTS heler should do sorting and deduplication of the scales and times when it builds the tables listing the available times/scales. Note, currently duplicated gain values aren't handled by GTS-helpers. Unsort the gain and time arrays in the test code, and add duplicates to time array in order to test the sorting and deduplicating works. Signed-off-by:

The sorting in iio_gts_build_avail_time_table is not working as intended. It could result in an out-of-bounds access when the time is zero. Here are more details: 1. When the gts->itime_table[i].time_us is zero, e.g., the time sequence is `3, 0, 1`, the inner for-loop will not terminate and do out-of-bound writes. This is because once `times[j] > new`, the value `new` will be added in the current position and the `times[j]` will be moved to `j+1` position, which makes the if-condition always hold. Meanwhile, idx will be added one, making the loop keep running without termination and out-of-bound write. 2. If none of the gts->itime_table[i].time_us is zero, the elements will just be copied without being sorted as described in the comment "Sort times from all tables to one and remove duplicates". For more details, please refer to https://lore.kernel.org/all/6dd0d822-046c-4dd2-9532-79d7ab96ec05@gmail.com. Reported-by:
