bfca85fa96 iio: resolver: ad2s1210: Use aligned_s64 instead of open coding alignment.
Use this new type to both slightly simplify the code and avoid
confusing static analysis tools. Mostly this series is about consistency
to avoid this code pattern getting copied into more drivers.

0300fa851f iio: resolver: ad2s1210: add reset gpio support
This adds support for the optional reset gpio to the ad2s1210 resolver
driver. If the gpio is present in the device tree, it is toggled during
driver probe before the reset of the device initialization. As per the
devicetree bindings, it is expected for the gpio to configured as active
low.

f9b9ff95be iio: resolver: ad2s1210: add support for adi,fixed-mode
It is possible to use the AD2S1210 with hardwired mode pins (A0 and A1).
According to the devicetree bindings, in this case the adi,fixed-mode
property will specify which of the 3 possible modes the mode pins are
hardwired for and the gpio-modes property is not allowed.

This adds support for the case where the mode pins are hardwired for
config mode. In this configuration, the position and value must be read
from the config register.

The case of hardwired position or velocity mode is not supported as
there would be no way to configure the device.

73006239ef iio: resolver: ad2s1210: remove of_match_ptr()
To be consistent with the rest of iio, remove of_match_ptr(). It does
not do anything useful here.

0f7fa242b3 iio: resolver: ad2s1210: remove DRV_NAME macro
The DRV_NAME macro is only used in one place in the ad2s1210 driver and
is not really needed so let's remove it.

This moves the ad2s1210 resolver driver out of staging. The driver has
been fixed up and is ready to graduate.
