Subject: [RFC PATCH v4 1/6] dt-bindings: npu: rockchip: add rockchip, rk3576-rknn-core
Date: Mon,  3 Aug 2026 21:41:20 +1200	[thread overview]
Message-ID: <20260803094125.3285895-2-gahing@gahingwoo.com> (raw)
In-Reply-To: <20260803094125.3285895-1-gahing@gahingwoo.com>

The RK3576 NPU has two cores of the same RKNN block the RK3588 binding
already describes, but no NPU SRAM supply, so sram-supply is required
for rockchip,rk3588-rknn-core only and rejected otherwise.
