[PATCH 0/6] Support for the NPU in Vim3

[PATCH 0/6] Support for the NPU in Vim3

[Tomeu Vizoso]

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
driver works basically unchanged.

Regards,

Tomeu

[PATCH 6/6] drm/etnaviv: add HWDB entry for VIPNano-QI.7120.0055

[Tomeu Vizoso]

This is a compute-only module marketed towards AI and vision
acceleration. This particular version can be found on the Amlogic A311D
SoC.

The feature bits are taken from the Khadas downstream kernel driver
6.4.4.3.310723AAA.

Weird it's not 0xff like on SM1, I looked at the A311D Datasheet and
HHI_NANOQ_MEM_PD_REG0 is 31:0 so 0xffffffff is correct, but
HHI_NANOQ_MEM_PD_REG1 is 23:0 so 0xFFFFFF is the correct value.

Bur please replace with GENMASK(31, 0) and GENMASK(23, 0) to align with the
rest of the code.

I think this should go in the npu node instead, those are for the VPU power domain.
