Happy to see this patch. It was on my TODO list,
but I hadn't had time to bringup my rk3326 device.
Same here, I just had an occasion to use it again these days so I jumped
on it!

A few comments.

The PX30 SoC includes both the VDPU2 and VEPU2 blocks which are similar
to the RK3399 (Hantro G1/H1 with shuffled registers).

Besides taking an extra clock, it also shares an interrupt with the IOMMU
so it's necessary to request the interrupt shared.

Perhaps it's time to rename this to rockchip_vpu_hw.c,
and merge rk3288 and rk3399? It's a nitpick, though.
Haha, I was thinking the exact same thing but wasn't sure it would be welcome!

I was thinking of rockchip_vpu2_hw.c or rockchip_vdpu2_hw.c since that's
apparently how it's called in Rockchip terminology: VDPU2 and VEPU2 for the
Hantro G1 and H1 with the shuffled register layout. The rk3288 stuff is
probably VDPU1/VEPU1 and we might want to rename it accordingly as well.
I'd rather keep it simple as rockchip_vpu_hw.c and just throw in there
all the rockchip stuff.
Do you also mean merging all the rk*_vpu_hw.c files into one or just covering
the general helpers (and not the platform-specific structures)?

Cheers,

Paul
