description: >
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.
