| 12 | description: | |
| 13 | The Zynq UltraScale+ MPSoC and Versal has several different resets. |
| 14 | |
| 15 | The PS reset subsystem is responsible for handling the external reset |
| 16 | input to the device and that all internal reset requirements are met |
| 17 | for the system (as a whole) and for the functional units. |
| 18 | |
| 19 | Please also refer to reset.txt in this directory for common reset |
| 20 | controller binding usage. Device nodes that need access to reset |
| 21 | lines should specify them as a reset phandle in their corresponding |
| 22 | node as specified in reset.txt. |
