Subject[PATCH v8 0/9] Add V4L2 driver for i.MX8 JPEG Encoder/Decoder
Date
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:

root@imx8qxpc0mek:/unit_tests/JPEG# ./v4l2-compliance -d /dev/video0 -s
v4l2-compliance 1.21.0-4707, 64 bits, 64-bit time_t
v4l2-compliance SHA: bf8d28efe5a3 2021-02-17 14:52:38
