Add vop found on rk3576, the main difference between rk3576 and the
previous vop is that each VP has its own interrupt line.

Changes in v12:
- Split from patch 10/13

Order your patches finally. It's v12 and you still send binding after
the user. Read carefully submitting bindings/patches.

What do you mean by "sending binding after user" here? 
I think PATCH 1~9 are fix and preparations, PATCH 13("drm/rockchip: vop2: Add support for rk3576")
is the user that uses the new binding.

Changes in v11:
- Remove redundant min/maxItems constraint

Changes in v10:
- Move interrupt-names back to top level
- Add constraint of interrupts for all platform
- Add constraint for all grf phandles
- Reorder some properties

Changes in v9:
- Drop 'vop-' prefix of interrupt-names.
- Add blank line between DT properties
- Remove list interrupt-names in top level

Changes in v8:
- Fix dt_binding_check errors
- ordered by soc name
- Link to the previous version:

Changes in v4:
- describe constraint SOC by SOC, as interrupts of rk3576 is very
  different from others
- Drop Krzysztof's Reviewed-by, as this version changed a lot.

Changes in v3:
- ordered by soc name
- Add description for newly added interrupt

Changes in v2:
- Add dt bindings

No. You did not implement my comment at all.

So again:
"Why minItems? Nothing in this patch makes sense for me. Neither changing
existing binding nor new binding for rk3576."

To address such comment, come with reasonable answer to "why". Not just
send the same. It's a waste of my time to keep reviewing the same.

Best regards,
Krzysztof
