Subject: [PATCH v6 0/8] Support for the NPU in Vim3

Hi,

This series adds support for the Verisilicon VIPNano-QI NPU in the A311D
as in the VIM3 board.

The IP is very closely based on previous Vivante GPUs, so the etnaviv
kernel driver works basically unchanged.

The userspace part of the driver is being reviewed at:

https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/18986

v2: Move reference to RESET_NNA to npu node (Neil)
v3: Fix indentation mistake (Neil)
v4: Add warning when etnaviv probes on a NPU (Lucas)
v5: Reorder HWDB commit to be the last (Lucas)
v6: Add patch to move the power domain to the SoC-specific dtsi (Neil)

Regards,

Tomeu
