[PATCH 0/3] media: imx-jpeg: Fix some motion-jpeg decoding issues

[ming . qian]

From: Ming Qian <ming.qian@xxxxxxxxxxx>

To support decoding motion-jpeg without DHT, driver will try to decode a
pattern jpeg before actual jpeg frame by use of linked descriptors
(This is called "repeat mode"), then the DHT in the pattern jpeg can be
used for decoding the motion-jpeg.

But there is some hardware limitation in the repeat mode, that may cause
corruption or decoding timeout.

Try to make workaround for these limitation in this patchset.

Ming Qian (3):
  media: imx-jpeg: Enhance error handling in buffer allocation
  media: imx-jpeg: Change the pattern size to 128x64
  media: imx-jpeg: Check decoding is ongoing for motion-jpeg
