Convert the driver to use regmap instead of I2C-specific functions. This
is done in preparation for splitting this driver into core and
I2C-specific code as well as introduction of SPI driver.

After sampling there should always be only one value in the FIFO.
This also applies to averaging mode as the averaging is done
chip-internally. So we don't have to loop and let the driver
complain if there's not exactly one value in the FIFO.
If the value belongs to a different channel then don't silently
swallow the value but complain.

There are a few more little cleanups that could be done on this driver, but
I don't think any are sufficient to justify not moving it out of staging.
It's a very simple driver (presumably for a simple part) so not much that can
go wrong. I think it was only ever in staging because that's where IIO was
as a whole at the time and then we forgot about it!

Previously it was called _info with instances as info. This caused some
confusion against the info structure that are used in the core of IIO.
Since this driver was written it's become a fairly strong convention to
use _state and st for instances so change to that.

There are some unanswered questions due to disagreements between the code
and various datasheets (including between different datasheets for the same
part).
I don't think that is necessarily a reason to keep it in staging however.

of luck find someone who has one of these to test!

This driver in some cases can busy wait for upwards of 100 ms. Since the

This patch adds support for the ultrasonic ranger srf04 of devantech.
This device is measuring the distance of objects in a range between 1 cm
and 3 meters and a theoretical resolution of 3 mm.
There are two GPIOs used:
- trigger: set as output to the device when the measurement should start
- echo: set by the device when the ultrasonic wave is sent out and reset
when the echo is recognized; this needs to be an interrupt input
The time between setting and resetting the echo pin is the time the
waveform needed for one round trip. This time is recorded in the interrupt
handler.
The distance is calculated in the read function by using the ultrasonic
speed at 20 degrees celsius which is about 343 m/s.
