The sharing is done by +multiplexing the PAD input/output signals. For each PAD there are up to +8 muxing options (called ALT modes). Since different modules require +different PAD settings (like pull up, keeper, etc) the IOMUXC controls +also the PAD settings parameters. + +Please refer to pinctrl-bindings.txt in this directory for details of the +common pinctrl bindings used by client devices, including the meaning of the +phrase "pin configuration node". + +Freescale IMX pin configuration node is a node of a group of pins which can be +used for a specific device or function. This node represents both mux and config +of the pins in that group. The 'mux' selects the function mode(also named mux +mode) this pin can work on and the 'config' configures various pad settings +such as pull-up, open drain, drive strength, etc. + +Required properties for iomux controller: +- compatible: "fsl,<soc>-iomuxc" + Please refer to each fsl,<soc>-pinctrl.txt binding doc for supported SoCs. + +Required properties for pin configuration node: +- fsl,pins: two integers array, represents a group of pins mux and config + setting.

The driver can use the function node's name and pin configuration node's + name describe the pin function and group hierarchy. + For example, Linux IMX pinctrl driver takes the function node's name + as the function name and pin configuration node's name as group name to + create the map table. +4.
