| 13 | i.MX8MM has TMU IP to allow temperature measurement, there are |
| 14 | currently two distinct major versions of the IP that is supported |
| 15 | by a single driver. The IP versions are named v1 and v2, v1 is |
| 16 | for i.MX8MM which has ONLY 1 sensor, v2 is for i.MX8MP which has |
| 17 | 2 sensors. |
