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
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
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:
48     clkout1, clkout2, mdio, dfe led0, dfe led1, ephy led0, ephy led1, ephy led2
51     spi, asc, cgu, jtag, exin, stp, gpt, mdio, ephy, dfe

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.
