+KernelVersion:  6.7
+Contact:	linux-iio@vger.kernel.org
+Description:
+		Reading returns a hex value containing the fault bit flags.
+
+		Bit	Description
+		---	-----------
+		D7	Sine/cosine inputs clipped
+		D6	Sine/cosine inputs below LOS threshold
+		D5	Sine/cosine inputs exceed DOS overrange threshold
+		D4	Sine/cosine inputs exceed DOS mismatch threshold
+		D3	Tracking error exceeds LOT threshold
+		D2	Velocity exceeds maximum tracking rate
+		D1	Phase error exceeds phase lock range
+		D0	Configuration parity error
+
+		Writing any value will clear any fault conditions.

+KernelVersion:  6.7
+Contact:	linux-iio@vger.kernel.org
+Description:
+		Reading returns the current Excitation Frequency in Hz. Writing
+		sets the Excitation Frequency and performs a software reset on
+		the device to apply the change. Valid values are 2000 (2kHz) to
+		20000 (20kHz).

+Description:
+		Reading returns the current Loss of Position Tracking Detection
+		High Threshold value. Writing sets the value. Valid values are
+		0 (0 deg) to 127 (9/18/45 deg). The interpretation of the value
+		depends on the selected resolution. To convert the value to
+		degrees, multiply by 0.35 for 10-bit resolution, multiply by
+		0.14 for 12-bit resolution or multiply by 0.09 for 14 and 16-bit
+		resolution.
