Subject: [PATCH v2 07/10] iio: magnetometer: bmc150: add mount matrix support
Date: Thu, 21 Feb 2019 18:02:52 +0100 [thread overview]
Message-ID: <92f9b04e6540612b8bb8450803df1fcda21e364b.1550768574.git.hns@goldelico.com> (raw)
In-Reply-To: <cover.1550768574.git.hns@goldelico.com>
This patch allows to read a mount-matrix device tree
property and report to user-space or in-kernel iio
clients.
