Subject: [PATCH V2 6/6] arm64: tegra: Add GTE nodes
Date: Tue, 14 Feb 2023 03:55:53 -0800 [thread overview]
Message-ID: <20230214115553.10416-7-dipenp@nvidia.com> (raw)
In-Reply-To: <20230214115553.10416-1-dipenp@nvidia.com>
Add GTE nodes for the tegra234. Also modify AON GTE nodes for the
tegra194 to remove nvidia,slice property and add nvidia,gpio-controller
propertyto 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.
