[PATCH v2 4/9] Staging: iio: accel: adis16201: Group register definitions

From: Himanshu Jha
Date: Fri Mar 16 2018 - 16:07:16 EST


Group register definitions with its register field bits to improve
readability and easy identification. A small comment is also added to
denote the purpose/functionality of the grouped register definitions.
