4 - compatible:	"lantiq,<chip>-pinctrl", where <chip> is:
10 - reg: Should contain the physical address and length of the gpio/pinmux
13 Please refer to pinctrl-bindings.txt in this directory for details of the
15 phrase "pin configuration node".
17 Lantiq's pin configuration nodes act as a container for an arbitrary number of
19 pin, a group, or a list of pins or groups. This configuration can include the
20 mux function to select on those group(s), and two pin configuration parameters:
21 pull-up and open-drain
27 other words, a subnode that lists a mux function but no pin configuration
28 parameters implies no information about any pin configuration parameters.
29 Similarly, a pin subnode that describes a pullup parameter implies no
30 information about e.g. the mux function.
34 Definition of mux function groups:
36 Required subnode-properties:
37 - lantiq,groups : An array of strings. Each string contains the name of a group.
39 - lantiq,function: A string containing the name of the function to mux to the
45   mux groups:
54   mux groups:
65   mux groups:
77   mux groups:
92   mux groups:
104 Definition of pin configurations:
106 Required subnode-properties:
107 - lantiq,pins : An array of strings. Each string contains the name of a pin.
110 Optional subnode-properties:
111 - lantiq,pull: Integer, representing the pull-down/up to apply to the pin.
113 - lantiq,open-drain: Boolean, enables open-drain on the defined pin.
