Subject: [PATCH v3 2/4] iio: imu: inv_mpu6050: add WoM event as accel event
Date: Mon, 11 Mar 2024 16:05:55 +0000 [thread overview]
Message-ID: <20240311160557.437337-3-inv.git-commit@tdk.com> (raw)
In-Reply-To: <20240311160557.437337-1-inv.git-commit@tdk.com>
From: Jean-Baptiste Maneyrol <jean-baptiste.maneyrol@tdk.com>
Add WoM (roc rising) event as accel x_or_y_or_z event for all chips >=
MPU-6500. This requires to create new MPU-6500 channels as default and
MPU-6050 channels for older chips.
