: ctrl setting name, e.g. uart2, spi0 - unique per mpp_mode
struct mvebu_mpp_ctrl_setting - describe a mpp ctrl setting : ctrl setting value : (optional) additional ctrl setting name, e.g. rts, cts : (optional) variant identifier mask : (private) flags to store gpi/gpo/gpio capabilities A ctrl_setting describes a specific internal mux function that a mpp pin can be switched to. The value (val) will be written in the corresponding register for common mpp pin configuration registers on MVEBU. SoC specific mpp_get/_set function may use val to distinguish between different settings. The name will be used to switch to this setting in DT description, e.g. marvell,function = "uart2". subname is only for debugging purposes. If name is one of "gpi", "gpo", "gpio" gpio capabilities are parsed during initialization and stored in flags. The variant can be used to combine different revisions of one SoC to a common pinctrl driver. It is matched (AND) with variant of soc_info to determine if a setting is available on the current SoC revision.
