b1ba43263e iio: imu: inv_icm42600: switch to use generic name irq get 
Use generic fwnode_irq_get_byname() for getting interrupt pin using
interrupt name. Only INT1 is supported by the driver currently.

If not found fallback to first defined interrupt to keep compatibility.

fbc18f27cf iio: adc: ti-adc128s052: Support ROHM BD79104 
The ROHM BD79104 ADC has identical SPI communication logic as the
ti-adc128s052. Eg, SPI transfer should be 16 clk cycles, conversion is
started when the CS is pulled low, and channel selection is done by
writing the channel ID after two zero bits. Data is contained in
big-endian format in the last 12 bits.

The BD79104 has two input voltage pins. Data sheet uses terms "vdd" and
"iovdd". The "vdd" is used also as an analog reference voltage. Hence
the driver expects finding these from the device-tree, instead of having
the "vref" only as TI's driver.

NOTE: The TI's data sheet[1] does show that the TI's IC does actually
have two voltage inputs as well. Pins are called Va (analog reference)
and Vd (digital supply pin) - but I keep the existing driver behaviour
for the TI's IC "as is", because I have no HW to test changes, and
because I have no real need to touch it.

NOTE II: The BD79104 requires SPI MODE 3.

NOTE III: I used evaluation board "BD79104FV-EVK-001" made by ROHM. With
this board I had to drop the SPI speed below the 20M which is mentioned
in the data-sheet [2]. This, however, may be a limitation of the EVK
board, not the component itself.

6c41d59072 iio: adc: ti-adc128s052: Be consistent with arrays 
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.

085831cfce dt-bindings: ROHM BD79104 ADC 
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.
