| 12 | description: | |
| 13 | The system reset controller can be used to reset various set of |
| 14 | peripherals. Device nodes that need access to reset lines should |
| 15 | specify them as a reset phandle in their corresponding node as |
| 16 | specified in reset.txt. |
| 17 | |
| 18 | For list of all valid reset indices see |
| 19 | <dt-bindings/reset/imx7-reset.h> for i.MX7, |
| 20 | <dt-bindings/reset/imx8mq-reset.h> for i.MX8MQ, i.MX8MM and i.MX8MN, |
| 21 | <dt-bindings/reset/imx8mp-reset.h> for i.MX8MP. |
