| 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 |
