Subject: [PATCH v2 1/3] dt-bindings: timestamp: Add Tegra264 support
Date: Wed, 8 Apr 2026 21:24:11 +0000 [thread overview]
Message-ID: <20260408212413.217692-2-suneelg@nvidia.com> (raw)
In-Reply-To: <20260408212413.217692-1-suneelg@nvidia.com>
Add timestamp provider support for the Tegra264 in devicetree
bindings. Tegra264 has two generic timestamping engines (GTE)
which are the always-on GTE (AON) and legacy interrupt
controller (LIC) GTE.
'nvidia,slices' property is deprecated and hence not allowed for
Tegra264.
Signed-off-by: Suneel Garapati <suneelg@nvidia.com>

v1:
- nvidia,slices property is deprecated and hence false for Tegra264
