iio: adc: Add the NXP SAR ADC support for the s32g2/3 platforms
The NXP S32G2 and S32G3 platforms integrate a successive approximation
register (SAR) ADC. Two instances are available, each providing 8
multiplexed input channels with 12-bit resolution. The conversion rate
is up to 1 Msps depending on the configuration and sampling window.
The SAR ADC supports raw, buffer, and trigger modes. It can operate
in both single-shot and continuous conversion modes, with optional
hardware triggering through the cross-trigger unit (CTU) or external
events. An internal prescaler allows adjusting the sampling clock,
while per-channel programmable sampling times provide fine-grained
trade-offs between accuracy and latency. Automatic calibration is
performed at probe time to minimize offset and gain errors.
All modes have been validated on the S32G274-RDB2 platform using an
externally generated square wave captured by the ADC. Tests covered
buffered streaming via IIO, trigger synchronization, and accuracy
verification against a precision laboratory signal source.
One potential scenario, not detected during testing, is that in some
corner cases the DMA may already have been armed for the next
transfer, which can lead dmaengine_tx_status() to return an incorrect
residue. The callback_result() operation—intended to supply the
residue directly and eliminate the need to call
dmaengine_tx_status()—also does not work. Attempting to use
dmaengine_pause() and dmaengine_resume() to prevent the residue from
being updated does not work either.
This potential scenario should apply to any driver using cyclic DMA.
However, no current driver actually handles this case, and they all rely
on the same acquisition routine (e.g., the STM32 implementation).
The NXP SAR acquisition routine has been used in production for several
years, which is a good indication of its robustness.
As the IIO is implementing the cyclic DMA support API, it is not worth
to do more spins to the current routine as it will go away when the
new API will be available.
The driver is derived from the BSP implementation and has been partly
rewritten to comply with upstream requirements. For this reason, all
contributors to the original code are listed as co-developers.

In addition, remove from this macro the channel type parameter and
hard-code IIO_ACCEL in the macro definition, since all callers use
IIO_ACCEL as channel type argument.

Pull block fixes from Jens Axboe:
- Always initialize DMA state, fixing a potentially nasty issue on the
block side
- btrfs zoned write fix with cached zone reports
- Fix corruption issues in bcache with chained bio's, and further make
it clear that the chained IO handler is simply a marker, it's not
code meant to be executed
- Kill old code dealing with synchronous IO polling in the block layer,
that has been dead for a long time. Only async polling is supported
these days
- Fix a lockdep issue in tag_set management, moving it to RCU
- Fix an issue with ublks bio_vec iteration
- Don't unconditionally enforce blocking issue of ublk control
commands, allow some of them with non-blocking issue as they
do not block

Pull io_uring fix from Jens Axboe:
"Single fix for io_uring headed to stable, fixing an issue introduced
with the min_wait support earlier this year, where SQPOLL didn't get
correctly woken if an event arrived once the event waiting has
finished the min_wait portion.
As we already have regression tests for this added and people
reporting new failures there, let's get this one flushed out
so it can bubble back down to stable as well"
