Subject: [PATCH v2 0/7] New DRM accel driver for Rockchip's RKNN NPU

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:

https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/29698

Signed-off-by: Tomeu Vizoso <tomeu@...euvizoso.net>

Changes in v2:
- Drop patch adding the rk3588 compatible to rockchip-iommu (Sebastian Reichel)
- Drop patch adding support for multiple power domains to rockchip-iommu (Sebastian Reichel)
- Link to v1: https://lore.kernel.org/r/20240612-6-10-rocket-v1-0-060e48eea250@tomeuvizoso.net
