Subject: [PATCH v5 0/4] media: amphion: add support for contiguous format

amphion vpu support non contiguous planes yuv format,
but when we make pipeline with other device,
the device may only support contiguous format,
for example, amphion encoder support NV12M,
but the capture device may only support NV12.
we can't connect them directly.

So to improve compatibility, driver can add support for contiguous
format in the same time.

Then encoder can support NV12 and NV12M,
decoder can support NV12_8L128 and NV12M_8L128.

v5
- make some change according to Tommaso's comments
v4
- set bytesperline of compressed formats to 0
v3
- negotiate bytesperline with user
- zero the reserved of v4l2_format
v2
-- fix an uninitialized array index read error
-- remove an used variable

Ming Qian (4):
  media: add nv12_8l128 and nv12_10be_8l128 video format.
  media: amphion: tell and handle contiguous and non contiguous format
  media: amphion: decoder add support for contiguous planes
  media: amphion: encoder add support for contiguous planes
