-      The VOP interrupt is shared by several interrupt sources, such as
-      frame start (VSYNC), line flag and other status interrupts.
+      For VOP version under rk3576, the interrupt is shared by several interrupt
+      sources, such as frame start (VSYNC), line flag and other interrupt status.
+      For VOP version from rk3576 there is a system interrupt for bus error, and
+      every video port has it's independent interrupts for vsync and other video
+      port related error interrupts.
