So no, Chris does not really control what the core of the driver does. The existing binding documentation says: * Marvell Armada 37xx SoC pin and gpio controller Each Armada 37xx SoC come with two pin and gpio controller one for the south bridge and the other for the north bridge. Inside this set of register the gpio latch allows exposing some configuration of the SoC and especially the clock frequency of the xtal. Hence, this node is a represent as syscon allowing sharing the register between multiple hardware block. So the syscon is there to allow the clock driver to share the register space. Andrew
