Hi,
This series adds support for the Verisilicon VIPNano-QI NPU in the A311D
as in the VIM3 board.
The IP is very closeley 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
Regards,
Tomeu
Tomeu Vizoso (5):
dt-bindings: reset: meson-g12a: Add missing NNA reset
dt-bindings: power: Add NNA power domain
soc: amlogic: meson-pwrc: Add NNA power domain for A311D
arm64: dts: Add DT node for the VIPNano-QI on the A311D
drm/etnaviv: add HWDB entry for VIPNano-QI.7120.0055
