+Subject: [PATCH] overlays: mpu6050: Add 'addr' parameter
+
+The mpu6050 starts up at address 0x68 by default, but can be set to
+0x69 if the ADO pin is pulled high. Give the overlay an addr parameter
+to allow devices at the alternate address to be used.
+
+See: https://github.com/Hexxeh/rpi-firmware/issues/252
