[PATCH v6 0/9] Add V4L2 driver for i.MX8 JPEG Encoder/Decoder

From: Mirela Rabulea (OSS)
Date: Tue Dec 15 2020 - 06:20:21 EST


From: Mirela Rabulea <mirela.rabulea@xxxxxxx>

This patch set adds the V4L2 driver for i.MX8QXP/QM JPEG encoder/decoder
and it's dependencies.
The driver was tested on i.MX8QXP, using a unit test application and
the v4l2-compliance tool, including the streaming tests for decoder & encoder.

The output of latest v4l2-compliance on i.MX8QXP, decoder & encoder:
