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.
