Those nodes can be pinmux nodes or -configuration nodes. - -Required properties for pinmux nodes are: - - groups: a list of pinmux groups. The list of all available groups - depends on the SoC and can be found in driver sources. - - function: the name of a function to activate for the specified set - of groups. The list of all available functions depends on the SoC - and can be found in driver sources. - -Required properties for configuration nodes: - - pins: a list of pin names - -Configuration nodes support the following generic properties, as -described in file pinctrl-bindings.txt: - - "bias-disable" - - "bias-pull-up" - - "bias-pull-down" - - "output-enable" - - "output-disable" - - "output-low" - - "output-high" - -Optional properties : - - drive-strength-microamp: Drive strength for the specified pins in uA. - This property is only valid for G12A and newer. - -=== Example === - - pinctrl: pinctrl@c1109880 { - compatible = "amlogic,meson8-cbus-pinctrl"; - reg = <0xc1109880 0x10>; - #address-cells = <1>; - #size-cells = <1>; - ranges; - - gpio: banks@c11080b0 { - reg = <0xc11080b0 0x28>, - <0xc11080e8 0x18>, - <0xc1108120 0x18>, - <0xc1108030 0x30>; - reg-names = "mux", "pull", "pull-enable", "gpio"; - gpio-controller; - #gpio-cells = <2>; - }; - - nand { - mux { - groups = "nand_io", "nand_io_ce0", "nand_io_ce1", - "nand_io_rb0", "nand_ale", "nand_cle", - "nand_wen_clk", "nand_ren_clk", "nand_dqs", - "nand_ce2", "nand_ce3"; - function = "nand"; - }; - }; - };
