[PATCH v14 06/15] dt-bindings: npu: rockchip: add rockchip,rk3576-rknn-core
From: Jiaxing Hu
Date: Thu Sep 24 2026 - 06:40:09 EST
The RK3576 NPU has two cores of the RKNN block this binding describes, with
two extra CBUF clocks, two power domains per core, one reset instead of
two, and no SRAM supply. Widen the properties and pin each SoC to its own
shape in allOf; sram-supply stays required for RK3588.
