The AD2S1210 monitors the internal error signal (difference between estimated angle and measured angle) to determine a loss of position tracking (LOT) condition. When the error value exceeds a threshold, a fault is triggered. This threshold is user-configurable. This patch converts the custom lot_high_thrd and lot_low_thrd attributes in the ad2s1210 driver to standard event attributes. This will allow tooling to be able to expose these in a generic way. Since the low threshold determines the hysteresis, it requires some special handling to expose the difference between the high and low register values as the hysteresis instead of exposing the low register value directly. The attributes also return the values in radians now as required by the ABI. Actually emitting the fault event will be done in a later patch.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
