Subject: [PATCH v15.1 03/13] media: amphion: add amphion vpu device driver
The amphion vpu codec ip contains encoder and decoder.
Windsor is the encoder, it supports to encode H.264.
Malone is the decoder, it features a powerful
video processing unit able to decode many formats,
such as H.264, HEVC, and other formats.
This Driver is for this IP that is based on the v4l2 mem2mem framework.
Supported SoCs are: IMX8QXP, IMX8QM
