Subject: [PATCH v6 1/2] staging: iio: accel: adis16240: enforce SPI mode on probe function
Date: Sat,  7 Dec 2019 01:53:38 -0300	[thread overview]
Message-ID: <20191207045339.9186-1-rodrigorsdc@gmail.com> (raw)

According to the datasheet, this driver supports only SPI mode 3,
so we should enforce it on probe function.
