2025-07-13iio: adc: mt6359: Move reference voltage to platform dataAngeloGioacchino Del Regno
In preparation to add support for new PMICs, add a `vref_mv` member to struct mtk_pmic_auxadc_info and use it in place of the AUXADC_VOLT_FULL definition. As a consequence, the definition was also removed.

In preparation for adding support for the AUXADC block found in the MT6363 PMIC, add the ready register index and mask to the mtk_pmic_auxadc_chan structure, populate those in the channel description for all of the already supported SoCs and make use of them in the .read_imp() callbacks.

2025-07-13iio: adc: ad4000: don't use shift_right()David Lechner
Drop use of shift_right() macro for unsigned value. The shift_right() macro is intended for signed values and is not needed for unsigned values. This was found by a static analysis tool [1].

2025-07-13iio: adc: ad_sigma_delta: add SPI offload supportDavid Lechner
Add SPI offload support to the ad_sigma_delta module. When the SPI controller has SPI offload capabilities, the module will now use that for buffered reads instead of the RDY interrupt trigger. Drivers that use the ad_sigma_delta module will have to opt into this by setting supports_spi_offload since each driver will likely need additional changes before SPI offload can be used. This will allow us to gradually enable SPI offload support for each driver.

2025-07-13iio: adc: ad_sigma_delta: use spi_optimize_message()David Lechner
Use spi_optimize_message() to improve the performance of buffered reads. By setting up the SPI message and pre-optimizing it in the buffer postenable callback, we can reduce overhead during each sample read. A rough estimate shows that this reduced the CPU usage of the interrupt handler thread from 22% to 16% using an EVAL-AD4112ARDZ board on a DE10-Nano (measuring a single channel at the default 6.2 kHz sample rate).

2025-07-13iio: adc: ad_sigma_delta: use BITS_TO_BYTES() macroDavid Lechner
Use the BITS_TO_BYTES() macro instead of dividing by 8 to convert bits to bytes. This makes it more obvious what unit conversion is taking place. In one instance, we also avoid the temporary assignment to a variable as it was confusing that reg_size was being used with two different units (bits and bytes). scan_type is factored out to reduce line wrapping.

2025-07-06iio: adc: ad7173: simplify clock enable/disableDavid Lechner
Use devm_clk_get_enabled() instead of devm_clk_get(), clk_prepare_enable(), devm_add_action_or_reset() to simplify the code as it effectively does the same thing. We can also drop ext_clk from struct ad7173_state since it is not used anywhere else.

The driver code is full of intXX_t and uintXX_t types which is not the pattern we use in the IIO subsystem. Switch the driver to use kernel internal types for that. No functional changes.
