301 	 * an IMU sample rate between (optimally) 1900 and 2100. After this, we can use the  in adis16475_set_freq()
303 	 * Optimally, the user sample rate is a multiple of both the IMU sample rate and  in adis16475_set_freq()
308 	 *	3. The last result becomes the IMU sample rate. Use that to calculate SYNC_SCALE  in adis16475_set_freq()
316 		 * If lcm is bigger than the IMU maximum sampling rate there's no perfect  in adis16475_set_freq()
318 		 * lower than the IMU max sample rate.  in adis16475_set_freq()
326 		 * This is not an hard requirement but it's not advised to run the IMU  in adis16475_set_freq()
1168 			 * In sync scaled mode, the IMU sample rate is the clk_freq * sync_scale.  in adis16475_config_sync_mode()
1169 			 * Hence, default the IMU sample rate to the highest multiple of the input  in adis16475_config_sync_mode()
1170 			 * clock lower than the IMU max sample rate. The optimal range is  in adis16475_config_sync_mode()
