[PATCH v5 10/10] media: hantro: Support NV12 on the G2 core
Andrzej Pietrasiewicz
andrzej.p at collabora.com
Wed Sep 22 03:11:46 PDT 2021
From: Ezequiel Garcia <ezequiel at collabora.com>
The G2 decoder block produces NV12 4x4 tiled format (NV12_4L4).
Enable the G2 post-processor block, in order to produce regular NV12.
The logic in hantro_postproc.c is leveraged to take care of allocating
the extra buffers and configure the post-processor, which is
significantly simpler than the one on the G1.
