| 28 | Support the one wire controller found in some members of the NXP |
| 29 | i.MX SoC family. |
| 30 | There are currently two silicon variants: |
| 31 | V1: i.MX21, i.MX27, i.MX31, i.MX51 |
| 32 | V2: i.MX25, i.MX35, i.MX50, i.MX53 |
| 33 | Newer i.MX SoCs such as the i.MX6 do not have one wire controllers. |
| 34 | |
| 35 | The driver supports both silicon variants. |
