Subject: [PATCH 5/5] iio: adis16480: fix devices that do not support sleep mode
Date: Fri, 3 Sep 2021 16:14:23 +0200	[thread overview]
Message-ID: <20210903141423.517028-6-nuno.sa@analog.com> (raw)
In-Reply-To: <20210903141423.517028-1-nuno.sa@analog.com>

Not all devices supported by this driver support being put to sleep
mode. For those devices, when calling 'adis16480_stop_device()' on the
unbind path, we where actually writing in the SYNC_SCALE register.

Fixes: 80cbc848c4fa0 ("iio: imu: adis16480: Add support for ADIS16490")
Fixes: 82e7a1b250170 ("iio: imu: adis16480: Add support for ADIS1649x family of devices")
