| 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. |

| description: > |
| 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. |
