Subject: [PATCH v3 5/5] iio: imu: bmi160: added mount-matrix support
Date: Wed, 20 May 2020 21:46:44 +0200 [thread overview]
Message-ID: <20200520194656.16218-6-jonathan.albrieux@gmail.com> (raw)
In-Reply-To: <20200520194656.16218-1-jonathan.albrieux@gmail.com>
Add mount-matrix binding support. As chip could have different orientations
a mount matrix support is needed to correctly translate these differences.
Signed-off-by: Jonathan Albrieux <jonathan.albrieux@gmail.com>
