This file needs to be included by devices that need to specify a set of pin
|
|
controller states. The maximum number of supported states is 5 (pinctrl-0 ...
|
|
pinctrl-4) but it can be incremented if required.
|
|
|
|
The bindings file for each pin controller driver implementation should provide
|
|
more information on what is the expected pin configuration format.
