The NVIDIA Deep Learning Accelerator (NVDLA) is an open source IP which is integrated into NVIDIA Jetson AGX Xavier, so add driver support for this accelerator.
NVDLA introduce: http://nvdla.org/primer.html
User mode driver: https://github.com/caihuoq/nvdla/tree/main/sw/umd
Cai Huoqing (2): MAINTAINERS: Add the driver info of the NVDLA drm/nvdla: Add driver support for NVDLA
Are there device tree bindings that are required to test this IP, are there additions for the Xavier SoCs to test them? They should also be published as patches as part of this series.
