From: Benjamin Gaignard <benjamin.gaignard@collabora.com>
Date: 2026-09-24 13:05:03
Also in:
imx, linux-devicetree, linux-media, linux-rockchip, lkml
Subsystem:
hantro vpu codec driver, media input infrastructure (v4l/dvb), the rest · Maintainers:
Nicolas Dufresne, Benjamin Gaignard, Philipp Zabel, Mauro Carvalho Chehab, Linus Torvalds
"nxp,imx8mq-vpu" is tagged as deprecated since:
commit f3116f2e52e6 ("media: dt-bindings: media: nxp, imx8mq-vpu: Split G1 and G2 nodes")
merged since v5.17-rc1.
There is more reference to it since that.
Remove for driver to clean up the code.

changes in v3:
- remove more dead code
changes in v2:
- have a separate patch for documentation
- rebased on v7.3-rc1
