[PATCH v16 06/16] dt-bindings: npu: rockchip: add rockchip,rk3576-rknn-core

[Jiaxing Hu]

The RK3576 and the RK3588 use the same NPU block, with different hardware
resources.

The RK3576 has two cores. Each core needs six clocks, two more than the
RK3588 (aclk_cbuf and hclk_cbuf), needs only one reset, and has no
sram-supply.

Define the requirements of each SoC in allOf. The RK3588 still requires
sram-supply.
