2025-05-21dt-bindings: iio: adc: Add ROHM BD79100GMatti Vaittinen
The ROHM BD79100G is a 12-bit ADC which can be read over SPI. Device has no MOSI pin. ADC results can be read from MISO by clocking in 16 bits. The 4 leading bits will be zero, last 12 containig the data. Device has only VCC supply pin, which acts also as a VFS, determining the voltage for full 12-bits. Specifying it is mandatory. This seems identical to the ti,ads7866. Support ROHM BU79100G using ti,ads7866 as a fallback.

Document the AD3530/AD3530R (8-channel) and AD3531/AD3531R (4-channel) low-power, 16-bit, buffered voltage output DACs with software- programmable gain controls. They provide full-scale output spans of 2.5V or 5V for reference voltages of 2.5V. These devices operate on a single 2.7V to 5.5V supply and are guaranteed to be monotonic by design. The "R" variants include a 2.5V, 5ppm/°C internal reference, which is disabled by default.

2025-04-22dt-bindings: ROHM BD79104 ADCMatti Vaittinen
The ROHM BD79104 is a 12-bit, 8-channel ADC with two power supply pins, connected to SPI. It's worth noting the IC requires SPI MODE 3, (CPHA = 1, CPOL = 1). I used an evaluation board "BD79104FV-EVK-001" from ROHM. With this board I had problems to have things working correctly with higher SPI clock frequencies. I didn't do thorough testing for maximum frequency though. First attempt was 40M, then 20M and finally 4M. With 20M it seemed as if the read values were shifted by 1 bit. With 4M it worked fine. The component data-sheet is not exact what comes to the maximum SPI frequency. It says SPI frequency is 20M - "unless othervice specified". Additionally, it says that maximum sampling rate is 1Mhz, and since reading a sample requires writing the channel (16 bits) and reading data (16 bits) - we get some upper limit from this. >From the "frequency is 20M, unless othervice specified" I picked the maximum frequency 20M - and did assumption that my problems with 20M weren't related to the BD79104 - but to the evaluation board "BD79104FV-EVK-001".

The usual mixture of new drivers, support in existing drivers for new devices, a range of features and general subsystem cleanup. Two merges of immutable branches in here: * SPI offload support. Culmination of a long effort to bring the ability to offload triggered sequences of SPI operations to specific hardware, allow high datarate acquisition over an SPI bus (if you have the right hardware / FPGA firmware) * GPIO set-array-helper - enables code simplification. New device support ================== adi,ad3552r-hs: - Add support for AD3541r and AD3542r via newly supported FPGA HDL. adi,ad4030 - New driver supporting the AD4030, AD4630 AD4630-16, AD4640-24, AD4632-16, AD4632-24 1 and 2 channel high precision SPI ADCs. adi,ad4851 - New driver and backend support for the AD4851, AD4852, AD4853, AD4854, AD4855, AD4846, AD4857, AD4858 and AD4858I high speed multichannel simultaneous sampling ADCs. adi,ad7191 - New driver for this 24-bit ADC for precision bridge applications, adi,ad7380 - Add support for the adaq4381-4 which is a 14-bit version of the already supported adaq4380-1 adi,adis16550 - New driver using the ADIS library (which needed extensions) for this IMU. brcm,apds9160 - New driver for this proximity and ambient light sensor. dynaimage,al3000a - New driver for this illuminance sensor. mcube,mc3230 - Add support for the mc3510c accelerometer with a different scale to existing supported parts (some rework preceded this) nxp,imx93 - Add compatibles for imx94 and imx95 which are fully compatible with imx93. rockchip,saradc - Add support for the RK3528 ADC - Add support for the RK3562 ADC silab,si7210 - New driver to support this I2C Hall effect magnetic position sensor. ti,ads7138 - New driver supporting the ADS7128 and AD7138 I2C ADCs. Staging driver drop =================== adi,adis16240 - Drop this impact sensor. Interesting part but complex hence never left staging due to ABI challenges. No longer readily available so drop driver. New features ============ Documentation - A really nice overview document introduce ADC terminology and how it maps to IIO. core - New description for FAULT events, used in the ad7173. - filter_type ABI used in ad4130. buffer-dmaengine - Split DMA channel request from buffer allocation (for SPI offload) - Add a new _with_handle setup variant. (for SPI offload) adi,adf4371 - Add control of reference clock type and support for frequency doubling where appropriate. adi,ad4695 - Support SPI offload. - Support oversampling control. adi,ad5791 - Support SPI offload. adi,ad7124 - Add channel calibration support. adi,ad7380: - Alert support (threshold interrupts) - SPI offload support. adi,ad7606 - Support writing registers when using backend enabling software control of modes. adi,ad7944 - Support SPI offload. adi,ad9832 - Use devm_regulator_get_enable() to simplify code. adi,ad9834 - Use devm_regulator_get_enable() to simplify code. adi,adxl345 - Improve IRQ handling code. - Add debug access to registers. bosch,bmi270 - Add temperature channel support. - Add data ready trigger. google,cross_ec - Add trace events. mcube,mc3230 - Add mount matrix support - Add an OF match table. Cleanup and minor bug fixes =========================== Tree wide: - Stop using iio_device_claim_direct_scoped() and introduce sparse friendly iio_device_claim/release_direct() The conditional scoped cleanup has proved hard to deal with, requiring workarounds for various compiler issues and in is rather non-intuitive so abandon that experiment. One of the attractions of that approach was that it made it much harder to have unbalanced claim/release bugs so instead introduce a conditional-lock style boolean returning new pair of functions. These are inline in the header and have __acquire and __release calls allowing sparse to detect lack of balance. There are occasional false positives but so far those have reflected complex code paths that benefited from cleanup anyway. The first set of driver conversions are in this pull request, more to follow next cycle. Various related cleanup in drivers. Removal of the _scoped code is completed and the definition removed. - Use of str_enable_disable() and similar helpers. - Don't set regmap cache to REGCACHE_NONE as that's the default anyway. - Change some caches from RBTREE to MAPLE reflecting best practice. - Use the new gpiod_multi_set_value_cansleep() - Make sure to grab direct mode for some calibrations paths. - Avoid using memcmp on structures when checking for matching channel configs.

Firmware contants do not fit the purpose of bindings because they are not independent IDs for abstractions. They are more or less just contants which better to wire via header with DT which is using it. That's why add deprecated message to dt binding header and also update existing dt bindings not to use macros from the header and replace them by it's value. Actually value is not relevant because it is only example. The similar changes have been done by commit 9d9292576810 ("dt-bindings: pinctrl: samsung: deprecate header with register constants").

Add interrupt-names INT1 and INT2 for the two interrupt lines of the sensor. When one of the two interrupt lines is connected, the interrupt as its interrupt-name, need to be declared in the devicetree. The driver then configures the sensor to indicate its events on either INT1 or INT2. If no interrupt is configured, then no interrupt-name should be configured, and vice versa. In this case the sensor runs in FIFO BYPASS mode. This allows sensor measurements, but none of the sensor events.
