Add support for the A/D 12-Bit successive approximation converters found
in the Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs.
RZ/T2H has two ADCs with 4 channels and one with 6.
RZ/N2H has two ADCs with 4 channels and one with 15.
Conversions can be performed in single or continuous mode. Result of the
conversion is stored in a 16-bit data register corresponding to each
channel.
The conversions can be started by a software trigger, a synchronous
trigger (from MTU or from ELC) or an asynchronous external trigger (from
ADTRGn# pin).
Only single mode with software trigger is supported for now.

Change the allocation strategy of the 8 SETUP registers from a least-
recently-used (LRU) to a first-come-first-served basis.
The AD7124 chips can have up to 16 channels enabled at a time in the
sequencer for buffered reads, but only have 8 SETUP configurations
(namely the OFFSET, GAIN, CONFIG and FILTER registers) that must be
shared among the 16 channels. This means some of the channels must use
the exact same configuration parameters so that they can share a single
SETUP group of registers. The previous LRU strategy did not keep track
of how many different configurations were requested at the same time,
so if there were more than 8 different configurations requested, some
channels would end up using the incorrect configuration because the slot
assigned to them would also be assigned to a different configuration
that wrote over it later.
Adding such tracking to solve this would make an already complex
algorithm even more complex. Instead we can replace it with a simpler
first-come-first-serve strategy. This makes it easy to track how many
different configurations are being requested at the same time. This
comes at the expense of slightly longer setup times for buffered reads
since all setup registers must be written each time when a buffered read
is enabled. But this is generally not considered a hot path where
performance is critical, so should be acceptable.
This new strategy also makes hardware debugging easier since SETUPs are
now assigned in a deterministic manner and in a logical order.

These attributes probably won't be used much, but since it is trivial

Fix temperature channel not working due to gain and offset not being
initialized. For channels other than the voltage ones calibration is
skipped (which is OK). However that results in the calibration register
values tracked in st->channels[i].cfg all being zero. These zeros are
later written to hardware before a measurement is made which caused the
raw temperature readings to be always 8388608 (0x800000).
To fix it, we just make sure the gain and offset values are set to the
default values and still return early without doing an internal
calibration.
While here, add a comment explaining why we don't bother calibrating
the temperature channel.

Wire up the .get_dma_dev() callback to use the DMA buffer infrastructure's
implementation. This ensures that DMABUF operations use the correct DMA
device for mapping, which is essential for proper operation on systems
where memory is mapped above the 32-bit range.
Without this callback, the core would fall back to using the IIO device's
parent, which may not have the appropriate DMA mask configuration for
high memory access.

Add a new buffer accessor .get_dma_dev() in order to get the
struct device responsible for actually providing the dma channel. We
cannot assume that we can use the parent of the IIO device for mapping
the DMA buffer. This becomes important on systems (like the Xilinx/AMD
zynqMP Ultrascale) where memory (or part of it) is mapped above the
32 bit range. On such systems and given that a device by default has
a dma mask of 32 bits we would then need to rely on bounce buffers (to
swiotlb) for mapping memory above the dma mask limit.
In the process, add an iio_buffer_get_dma_dev() helper function to get
the proper DMA device.

Correction of meas_time_us initialization based on an observation and
partial patch by David Lechner.
The constant part of the measurement time (as described in the
datasheet and implemented in the BM(P/E)2 Sensor API) was apparently
forgotten (it was already correctly applied for the BMP380) and is now
used.
There was also another thinko in bmp280_wait_conv:
data->oversampling_humid can actually have a value of 0 (for an
oversampling_ratio of 1), so it can not be used to detect the presence
of the humidity measurement capability. Use
data->chip_info->oversampling_humid_avail instead, which is NULL for
chips that cannot measure humidity and therefore must skip that part
of the calculation.

Add a special case to double the SPI offload trigger rate when all
channels of a single-ended chip are enabled in a buffered read.
The single-ended chips in the AD738x family can only do simultaneous
sampling of half their channels and have a multiplexer to allow reading
the other half. To comply with the IIO definition of sampling_frequency,
we need to trigger twice as often when the sequencer is enabled to so
that both banks can be read in a single sample period.

Previously, the driver always used the amount of precision bits of
differential input channels to provide the scale to mV. Though,
differential and common-mode voltage channels have different amount of
precision bits and the correct number of precision bits must be considered

number of precision bits to provide the correct scale value for each

Cleanup and minor fixes
=======================
core
- Switch info_mask fields to be unsigned. Not clear why they were ever
signed.
- Fix handling of negative channel scale in iio_convert_raw_to_processed()
- Fix offset handling for channels without a scale attribute.
- Improve the precision of scaling slightly.
- Drop apparent handling of IIO_CHAN_INFO_PROCESSED for devices that don't
have any such channels.
various
- Drop many pm_runtime_mark_last_busy() calls now
pm_runtime_put_autosuspend() calls it internally.
- Drop dev_err_probe() calls where the error code is hard coded as -ENOMEM
as they don't do anything.
- Drop dev_err() calls where the error code is -ENOMEM. This will reduce

so unlikely we need these prints.
current-sense-amplifier
- Add #io-channels property this channel to be used by a consumer driver.
adi,ad7124
- Fix incorrect clocks dt-binding property.
- Make the mclk clock optional in DT - this is internal to the ADC so should

- Deploy guard() to clean up some lock handling.

bosch,bmi270
