Subject: [PATCH 0/5] Add V4L2 driver for i.MX8 JPEG Encoder/Decoder

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, which passes when run on the encoder/decoder dev
node, without any other parameters:
v4l2-compliance -d /dev/video0
v4l2-compliance -d /dev/video1
v4l2-compliance SHA: 2ff1e6b3d67dbbdde212c8cf0de603f9f52078ed, 64 bits

The first patch "Add packed YUV444 24bpp pixel format" was already reviewed
upstream, but not accepted because there was no driver using this format,
until now. This pixel format, YUV444 24bpp, is now used and needed by the
i.MX8QXP/QM JPEG encoder/decoder driver.

Mirela Rabulea (5):
  media: v4l: Add packed YUV444 24bpp pixel format
  firmware: imx: scu-pd: Add power domains for imx-jpeg
  media: dt-bindings: Add bindings for i.MX8QXP/QM JPEG driver
  media: imx-jpeg: Add V4L2 driver for i.MX8 JPEG Encoder/Decoder
  arm64: dts: imx8qxp: Add jpeg encoder/decoder nodes
