2025-04-22iio: health: max30102: Switch to sparse friendly ↵Jonathan Cameron
iio_device_claim/release_direct() These new functions allow sparse to find failures to release direct mode reducing chances of bugs over the claim_direct_mode() functions that are deprecated. This particular case is about ensuring the mode does not change rather than ensuring we are in direct mode. A follow up may cleanup the buffer mode claim.

2025-04-22iio: adc: ad7124: Remove ability to write filter_low_pass_3db_frequencyUwe Kleine-König
There are several issues with the function that implements writing to the filter_low_pass_3db_frequency property: - The sinc3 factor should be 0.272 not 0.262 (this is fixed for the reading side in the previous patch). - For freq > 1 the if condition is always true so the sinc4 filter is hardly ever chosen. - In the nearly always taken if branch the filter is set to sinc3, but the frequency is set for sinc4. (And vice versa in the else branch.) This is broken enough to justify the claim that there isn't any serious user. Also it it counter-intuitive that setting the 3db frequency modifies the sample frequency and the filter type. So drop the ability to write that property.

2025-04-22iio: adc: ad4000: Add support for SPI offloadMarcelo Schmitt
FPGA HDL projects can include a PWM generator in addition to SPI-Engine. The PWM IP is used to trigger SPI-Engine offload modules that in turn set SPI-Engine to execute transfers to poll data from the ADC. That allows data to be read at the maximum sample rates. Also, it is possible to set a specific sample rate by setting the proper PWM duty cycle and related state parameters, thus allowing an adjustable ADC sample rate when a PWM (offload trigger) is used in combination with SPI-Engine. Add support for SPI offload.

2025-04-22iio: dac: bd79703: Support ROHM BD79702Matti Vaittinen
The ROHM BD79702 is similar to the BD79703, except that it has only 4 channels whereas BD79703 has 6 channels. The channel 'addresses' of the first two channels (used to identify the channel when data is read over SPI) are same for both ICs. The next two channels of the BD79702 have same addresses as the last two channels of the BD79703. This means the BD79702 channel addresses do not follow the channel numbers with a constant offset. Thus, we need to specify the addresses separately, instead of directly deriving them from the channel number with a constant offset. It's worth noting that the data-sheet describes the BD79702 as a device having channels 1,2,5 and 6. The driver however represents channels 0,1,2,3 to the users - with no gaps in the numbering - which may be more familiar view for the application software. Support ROHM BD79702 DAC.

The BD79700 and BD79701 look like almost exact subsets of the BD79703. The BD79703 contains 6 channels (channels 0 to 5). The BD79700 provides only 2 channels, matching the BD79703 channels 0 and 1. The BD79701 provides 3 channels (matching BD79703 channels 0, 1, and 2). Furthermore, the BD79700 and BD79701 do not have separate VFS pin but use VCC for the full-scale voltage.

2025-04-22iio: dac: bd79703 Store device address to 'address'Matti Vaittinen
The ROHM BD79703 needs to identify a channel which we are reading from in the SPI transfers. This can be seen as an address for the device. For the bd79703 the address is nicely aligned with the channel number, so the driver uses the channel ID for the SPI transfers. This, however, does not need to be the case. The iio_chan_spec has a separate 'address' field, which we can populate directly with this information. This helps adding new ICs like the ROHM BD79702 where the channel ID is different from this address to be handled by this driver, so we don't need to have separate, IC specific mapping for channel numbers <=> addresses. Make the 'address' field in the iio_chan_spec to contain the SPI protocol address for the channel, and use this value in the transfers.

2025-04-22iio: adc: ti-ads1015: Use guard(mutex) and factor out code for INFO_RAWJonathan Cameron
By use of automatic lock release and introducing a new utility function to handle the core activity of reading the ADC channel, many more complex code flows can be replaced by direct returns.
