From b36e8257641a043764c62240316610c81e36376c Mon Sep 17 00:00:00 2001 From: "Andrew F. Davis" Date: Sun, 1 May 2016 15:36:59 -0500 Subject: [PATCH] iio: health/afe440x: Use regmap fields These drivers can use regmap fields to access fields in registers, this allows us to remove some macros/defines and simplify code, do this here.
