"drivers needing both pin control and GPIOs" below for details. But in some
situations a cross-subsystem mapping between pins and GPIOs is needed.
-Since the pin controller subsystem have its pinspace local to the pin
+Since the pin controller subsystem has its pinspace local to the pin
controller we need a mapping so that the pin control subsystem can figure out
which pin controller handles control of a certain GPIO pin. Since a single
pin controller may be muxing several GPIO ranges (typically SoCs that have
