2025-04-22iio: adc: ti-adc128s052: Simplify using guard(mutex)Matti Vaittinen
Error path in ADC reading function can be slighly simplified using the guard(mutex). Use guard(mutex) and document the mutex purpose.

Quoting Jonathan: "Whilst it doesn't bring huge advantage, now we have devm_mutex_init() it seems reasonable to use it and maybe catch a use after free for the lock" Switch to use devm_mutex_init() while working on this file.

2025-04-22iio: adc: ti-adc128s052: Be consistent with arraysMatti Vaittinen
The ti-adc128s052 driver has NULL terminated ID arrays for the of_device_id, spi_device_id and acpi_device_id. All of these are terminated by having an empty string as the last member of an array. Only the of_device_id array uses the /* sentinel */ comment. It's better to be consistent. This /* sentinel */ comment serves no real purpose these days as people are used to seeing these ID lists terminated with an empty array element. Drop the /* sentinel */ from the of_device_id.

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". Add bindings for the ROHM BD79104 ADC.
