From: Thierry Reding <treding@xxxxxxxxxx>
Tegra194 has two separate instances of the pin controller, one called
AON (in the always-on domain) and another called "main". Instead of
treating them as a single pin controller, split them up into two
separate controllers. Doing so allows the mapping between the pinmux and
GPIO controllers to be trivial identity mappings and more cleanly
separates the AON from the main IP blocks.
