17 includes pinmux and various pin configuration parameters, such as pull-up,
20 Each configuration node can consist of multiple nodes describing the pinmux
24 The following generic properties as defined in pinctrl-bindings.txt are valid
25 to specify in a pinmux subnode:
29 - pins:           An array of strings, each string containing the name of a pin.
32                   MIO0 - MIO111
34 - groups:         An array of strings, each string containing the name of a pin
65 - function:       An array of strings, each string containing the name of the
66                   pinmux functions. The following are the list of pinmux
90 - bias-disable:  No arguments. Disable pin bias.
91 - bias-pull-down: No arguments. The specified pins should be configured as
93 - bias-pull-up:   No arguments. The specified pins should be configured as
95 - input-schmitt-enable: No arguments: Enable schmitt trigger for the specified
97 - input-schmitt-disable: No arguments: Disable schmitt trigger for the specified
99 - slew-rate:      Integer. Sets slew rate for the specified pins.
101                   <0>  - Slow
