This patch is to add driver for the DPAA2 1588 timer module (RTC)
which interfaces to up to an unlimited number of 10/100/1000 or
10G ethernet MACs, providing current time, alarm, and fiper support.
The 1588 IP control block includes these distinctive features.
- External GPIO trigger for time-sta

Move the iio driver for the ad2s1200 and ad2s1205 resolver-to-digital
converter out of staging, into mainline iio subsystems.

Changes in v3:
- Add mention of ad2s1205 in commit message.

A scaling factor of approximately 2 * Pi / (2^12 -1) is added,
to scale the 12-bits angular position to radians.
A return type of IIO_VAL_INT_PLUS_NANO is used, so that the scale of
both the angle channel and angular velocity channel has 7 significant
digits.

Changes in v3:
- Documentation is added to Documentation/devicetree/bindings/iio/resolver
instead of staging directory.
- Add mention to ad2s1205 device.

The iio resolver drivers in staging use angle channels. This patch
add missing documentation for this type of channel.
As was discussed in [1], radians is chosen as the unit, to match the
unit of angular velocity.

The sysfs iio ABI states radians per second is expected as the unit for
angular velocity, but the 12-bit angular velocity register has rps
as its unit. So a scaling factor of approximately 2 * Pi is
added to the angular velocity channel.

The manual states that the data is contained in the upper 12 bits
of the 16 bits read by spi. The code that extracts these 12 bits
is correct for both be and le machines, but this is not clear
from a first glance.
To improve readability the relevant expressions are replaced
with equivalent express
