Hi Conor,

My fault, mistake on "to" when sending mail, please ignore this serie there are no bindings/DT in it.
Sorry for disturbance.

Best regards,
Hugues.

Hi all,

Here is an RFC to support VP8 encoding using Hantro H1 hardware
of STM32MP25 SoCs (Verisilicon VC8000NanoE IP).
This work is derived from work done to support Rockchip RK3399
VPU2 in RFC [1] with a reshuffling of registers to match H1
register set.

This has been tested on STM32MP257F-EV1 evaluation board using
GStreamer userspace [2]:
gst-launch-1.0 videotestsrc num-buffers=500 ! video/x-raw,width=640,height=480 \
! v4l2slvp8enc ! queue ! matroskamux ! filesink location=test_vp8.mkv

For the sake of simplicity I have embedded here the RFC [1] before the
changes related to this exact RFC, all rebased on v6.6 + STM32MP25
hardware codecs support [3].

I don't see any bindings etc here, what is it that you think I would
care about looking at in this RFC series?

Thanks,
Conor.
