53 Please refer to pinctrl-bindings.txt in this directory for details of the
54 common pinctrl bindings used by client devices, including the meaning of the
55 phrase "pin configuration node".
57 The pin configuration nodes act as a container for an arbitrary number of
59 pin or a list of pins. This configuration can include the
60 mux function to select on those pin(s), and various pin configuration
69 other words, a subnode that lists a mux function but no pin configuration
70 parameters implies no information about any pin configuration parameters.
71 Similarly, a pin subnode that describes a pullup parameter implies no
