Need NPU driver 1.5

rockchip just release rknn-toolkit 1.6 version in yesterday , but it need driver version >=1.5 , where can I get NPU driver 1.5?
Please help, Thanks.

The driver is included in the v1.6 rknn-toolkits release.

I only find npu_transfer_proxy in rknn-toolkits 1.6 release, after update this file, npu driver version still not update to >=1.5, how can I get npu driver version >=1.5? Thanks.
