Subject: [PATCH v2] iio: cros_ec: Set Gyroscope default frequency to 25Hz
Date: Tue, 28 Jul 2020 13:48:25 -0700
Message-ID: <20200728204825.3312921-1-gwendal@chromium.org> (raw)

BMI160 Minimium gyroscope frequency in normal mode is 25Hz.
When older EC firmware do not report their sensors frequencies,
use 25Hz as the minimum for gyroscope to be sure it works on BMI160.

Fixes: ae7b02ad2f32d ("iio: common: cros_ec_sensors: Expose cros_ec_sensors
frequency range via iio sysfs")
