2025-04-22iio: light: vcnl4000: 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. To simplify the code whilst making the change (and avoid potential false positives from sparse), split the enabling and disabling of thresholds into separate functions. This could have been done in two steps by splitting the functions first, but would have meant rewriting the enable function twice.

2025-04-22iio: adc: ad7606: dynamically allocate channel infoDavid Lechner
Refactor the ad7606 drivers to dynamically allocate the channel info. The channel info was getting a bit unwieldy. In some cases, the indio_dev->channels field was getting assigned up to 3 different times, each in a different function, making it difficult to see where the info was coming from. This problem stems from the number of permutations of the channel array needed to support various modes of operation and data buses. We already have 4 per chip (hardware mode, software mode, AXI ADC backend and AXI ADC backend with software mode) and we intend to add two more per chip when adding SPI offload support. To make it easier to read and maintain, move all of the channel setup to a single function that dynamically allocates and fills in the channel info. Additionally, this lets us remove some hacks where we had to compute an offset due to the fact that sometimes there was a soft timestamp channel at the start of the array. Now the timestamp channel is always at the end of the array as is typical in other drivers.

2025-04-22iio: adc: Support ROHM BD79124 ADCMatti Vaittinen
The ROHM BD79124 is a 12-bit, 8-channel, SAR ADC. The ADC supports an automatic measurement mode, with an alarm interrupt for out-of-window measurements. The window is configurable for each channel. The I2C protocol for manual start of the measurement and data reading is somewhat peculiar. It requires the master to do clock stretching after sending the I2C slave-address until the slave has captured the data. Needless to say this is not well suopported by the I2C controllers. Thus do not support the BD79124's manual measurement mode but implement the measurements using automatic measurement mode, relying on the BD79124's ability of storing latest measurements into register. Support also configuring the threshold events for detecting the out-of-window events. The BD79124 keeps asserting IRQ for as long as the measured voltage is out of the configured window. Thus, prevent the user-space from choking on the events and mask the received event for a fixed duration (1 second) when an event is handled. The ADC input pins can be also configured as general purpose outputs. Make those pins which don't have corresponding ADC channel node in the device-tree controllable as GPO.
