| 13 | Please refer to pinctrl-bindings.txt in this directory for details of the |
| 14 | common pinctrl bindings used by client devices, including the meaning of the |
| 15 | phrase "pin configuration node". |
| 16 | |
| 17 | ZynqMP's pin configuration nodes act as a container for an arbitrary number of |
| 18 | subnodes. Each of these subnodes represents some desired configuration for a |
| 19 | pin, a group, or a list of pins or groups. This configuration can include the |
| 20 | mux function to select on those pin(s)/group(s), and various pin configuration |
| 21 | parameters, such as pull-up, slew rate, etc. |
| 22 | |
| 23 | Each configuration node can consist of multiple nodes describing the pinmux and |
| 24 | pinconf options. Those nodes can be pinmux nodes or pinconf nodes. |
| 25 | |
| 26 | The name of each subnode is not important; all subnodes should be enumerated |
| 27 | and processed purely based on their content. |
