| description: | | |
| Pin controller devices should contain the pin configuration nodes that client | |
| devices reference. | |
| The contents of each of those pin configuration child nodes is defined | |
| entirely by the binding for the individual pin controller device. There | |
| exists no common standard for this content. The pinctrl framework only | |
| provides generic helper bindings that the pin controller driver can use. | |
| The pin configuration nodes need not be direct children of the pin controller | |
| device; they may be grandchildren, for example. Whether this is legal, and | |
| whether there is any interaction between the child and intermediate parent | |
| nodes, is again defined entirely by the binding for the individual pin | |
| controller device. | |

| Indicates that the OS can use the boot default pin configuration. This | |
| allows using an OS that does not have a driver for the pin controller. | |
| This property can be set either globally for the pin controller or in | |
| child nodes for individual pin group control. | |
