I'm also doing work with the hantro node on rk3588 which has both vdpu
and vepu. Discussions can be found here[1]. If I enable the jpeg encoder
at feb50000, would it cause any side effects if other jpeg encoders in
your patch are enabled? And what's the disadvantage of enabling multi
jpeg endoers in devicetree?
