[PATCH v5 00/10] New DRM accel driver for Rockchip's RKNN NPU

[Tomeu Vizoso]

This series adds a new driver for the NPU that Rockchip includes in its
newer SoCs, developed by them on the NVDLA base.

In its current form, it supports the specific NPU in the RK3588 SoC.

The userspace driver is part of Mesa and an initial draft can be found at:
