I'm guessing dev is a device bus of some sort? What is > xsmi? Some sort of extended System Management Interface? And m? "dev" is the Device Bus indeed, used for example for NOR or NAND. "m" stands for memory. The m(decc) signal is asserted when a memory ECC error occurred, while the m(vtt) signal is the DRAM VTT Power Control signal. No idea what this is. "xsmi" is indeed some other SMI bus, not clear yet how it compares to the regular SMI bus. Both "dev" and "m" are already used by many of the existing pinctrl DT bindings for Marvell platforms, so I'm not sure documenting them specifically in the Armada 39x pinctrl DT binding document makes a lot of sense. Where should we document them, then? In the generic 'marvell,mvebu-pinctrl.txt' DT binding file ?
