Each pin has 4 multiplexing functions, and generally, the 4th +function is GPIO. The configuration on the pins includes drive strength, +voltage and pull-up. + +Required properties: +- compatible: "fsl,imx23-pinctrl" or "fsl,imx28-pinctrl" +- reg: Should contain the register physical address and length for the + pin controller. + +Please refer to pinctrl-bindings.txt in this directory for details of the +common pinctrl bindings used by client devices. + +The node of mxs pin controller acts as a container for an arbitrary number of +subnodes. Each of these subnodes represents some desired configuration for +a group of pins, and only affects those parameters that are explicitly listed. +In other words, a subnode that describes a drive strength parameter implies no +information about pull-up. For this reason, even seemingly boolean values are +actually tristates in this binding: unspecified, off, or on. Unspecified is +represented as an absent property, and off/on are represented as integer +values 0 and 1. + +Those subnodes under mxs pin controller node will fall into two categories. +One is to set up a group of pins for a function, both mux selection and pin +configurations, and it's called group node in the binding document. The other +one is to adjust the pin configuration for some particular pins that need a +different configuration than what is defined in group node. The binding +document calls this type of node config node. + +On mxs, there is no hardware pin group. The pin group in this binding only +means a group of pins put together for particular peripheral to work in +particular function, like SSP0 functioning as mmc0-8bit. That said, the +group node should include all the pins needed for one function rather than +having these pins defined in several group nodes. It also means each of +"pinctrl-*" phandle in client device node should only have one group node +pointed in there, while the phandle can have multiple config node referenced +there to adjust configurations for some pins in the group. + +Required subnode-properties: +- fsl,pinmux-ids: An integer array. Each integer in the array specify a pin + with given mux function, with bank, pin and mux packed as below. + + [15..12] : bank number + [11..4] : pin number + [3..0] : mux selection + + This integer with mux selection packed is used as an entity by both group + and config nodes to identify a pin. The mux selection in the integer takes + effects only on group node, and will get ignored by driver with config node, + since config node is only meant to set up pin configurations. + + Valid values for these integers are listed below. + +- reg: Should be the index of the group nodes for same function. This property + is required only for group nodes, and should not be present in any config + nodes. + +Optional subnode-properties: +- fsl,drive-strength: Integer. + 0: 4 mA + 1: 8 mA + 2: 12 mA + 3: 16 mA +- fsl,voltage: Integer. + 0: 1.8 V + 1: 3.3 V +- fsl,pull-up: Integer. + 0: Disable the internal pull-up + 1: Enable the internal pull-up + +Examples: + +pinctrl@80018000 { + #address-cells = <1>; + #size-cells = <0>; + compatible = "fsl,imx28-pinctrl"; + reg = <0x80018000 2000>; + + mmc0_8bit_pins_a: mmc0-8bit@0 { + reg = <0>; + fsl,pinmux-ids = < + 0x2000 0x2010 0x2020 0x2030 + 0x2040 0x2050 0x2060 0x2070 + 0x2080 0x2090 0x20a0>; + fsl,drive-strength = <1>; + fsl,voltage = <1>; + fsl,pull-up = <1>; + }; + + mmc_cd_cfg: mmc-cd-cfg { + fsl,pinmux-ids = <0x2090>; + fsl,pull-up = <0>; + }; + + mmc_sck_cfg: mmc-sck-cfg { + fsl,pinmux-ids = <0x20a0>; + fsl,drive-strength = <2>; + fsl,pull-up = <0>; + }; +}; + +In this example, group node mmc0-8bit defines a group of pins for mxs SSP0 +to function as a 8-bit mmc device, with 8mA, 3.3V and pull-up configurations +applied on all these pins. And config nodes mmc-cd-cfg and mmc-sck-cfg are +adjusting the configuration for pins card-detection and clock from what group +node mmc0-8bit defines.
