Hi!
> Add a single imx-media mem2mem video device that uses the IPU IC PP

> conversion.
> On i.MX6Q/DL SoCs with two IPUs currently only the first IPU is used.

> The hardware only supports writing to destination buffers up to

Point of SPDX is that the last 4 lines can be removed...and if you
want GPL-2.0+ as you state (and I like that), you should also say so
in SPDX.
Thanks,
Pavel
