Subject: [PATCH v3 0/6] ARM: dts: sun8i: v3s: Enable video decoder
Date:   Mon, 16 Nov 2020 13:56:11 +0100

First patch extends cedrus capability to all decoders
because V3s missing MPEG2 decoder.

Next two patches add system control node (SRAM C1) and 
next three patches add support for Cedrus VPU.

Tested on "Lichee Zero" V3s platform with testing LCD patch
( https://github.com/mcerveny/linux/tree/media_tree_for-v5.11e )
and V4L2 raw API testing utility (updated to v5.10)
( https://github.com/mcerveny/v4l2-request-test ):
- enabled LCD (DRM dual VI and sigle UI planes)
- added RGB panel
- enabled PWM
- need additional patch https://git.linuxtv.org/media_tree.git/commit/?h=fixes&id=9ac924b98728c3733c91c6c59fc410827d0da49f

There is low memory on V3s (64MB) and maximum must be available to CMA:
- CONFIG_CMA_SIZE_MBYTES=28
- add swap to swapout other processes
- decrease buffers in v4l2-request-test (.buffers_count from 16 to 8)

Only H.264 decoder working - MPEG and H.265 unsupported by V3s,
JPEG/MJPEG still unimplemented, encoder unimplemented

best regards,
Martin

Changes since v2:
- updated/rebased to https://git.linuxtv.org/hverkuil/media_tree.git/?h=for-v5.11e
- some parts of patches implemeted by others
- updated R40
Changes since v1:
- patch 0005 rename
- added testing description
