[PATCH V3 6/6] arm64: tegra: Add GTE nodes

From: Dipen Patel
Date: Fri Mar 10 2023 - 14:07:07 EST


Add GTE nodes for the tegra234. Also modify AON GTE nodes for the
tegra194 to remove nvidia,slice property and add nvidia,gpio-controller
property to specify AON GPIO controller node so that GTE driver can
do namespace conversion between GPIO lines provided by the gpiolib
framework and hardware timestamping engine subsystem.
