Subject: [PATCH v2 8/8] soc: tegra: cbb: add support for cbb fabrics in Tegra254
Date: Thu, 3 Jul 2025 16:08:29 +0530 [thread overview]
Message-ID: <20250703103829.1721024-9-sumitg@nvidia.com> (raw)
In-Reply-To: <20250703103829.1721024-1-sumitg@nvidia.com>
Add support for CBB 2.0 based fabrics in Tegra254 SoC using ACPI.
Fabrics reporting errors are: C2C, GPU, Display_Cluster.
Tegra254 is using hardware based lookup to get target node address.
So, the target_map tables for each fabric are not needed now.
