Subject: [PATCH 1/4] dt-bindings: memory: tegra: Add Tegra264 support
Date: Tue,  8 Jul 2025 12:52:42 +0200	[thread overview]
Message-ID: <20250708105245.1516143-2-thierry.reding@gmail.com> (raw)
In-Reply-To: <20250708105245.1516143-1-thierry.reding@gmail.com>

From: Sumit Gupta <sumitg@nvidia.com>

Add bindings for the Memory Controller (MC) and External Memory
Controller (EMC) found on the Tegra264 SoC. Tegra264 SoC has a different
number of interrupt lines for MC sub-units: UCF_SOC, hub, hub common,
syncpoint and MC channel. The total number of interrupt lines is eight.
Update maxItems for MC interrupts accordingly.
