What does the last 'e' in 'jpege' stand for? If it is 'encoding', then I prefer
that you rename it to rk3399_vpu_hw_jpeg_enc.c (ditto elsewhere).

It appears that this driver is prepared for JPEG and H264 decoding in the
future as well, correct?
Wasn't the H264 decoding stateless for the Rockchip VPU?
It's a bit confusing looking at this. If the intention is to add JPEG and
H264 decoding to this driver as well, then I would feel more comfortable
if this driver is added to staging first.
