Maybe I should also include i.MX8MM interconnect and make it
a separate patch, then i.MX8MP/i.MX8MM just use their own
names just like other properities. In final, as below:

Tow patch:
  1. Add interconnect property for i.MX8MM VPU BLK CTRL
  2. Add i.MX8MP VPU BLK CTRL dt bindings

In top-level:
+ interconnects:
+    maxItems: 3
 
+   interconnect-names:
+      maxItems: 3

For i.MX8MM
+        interconnects:
+          items:
+            - description: G1 decoder interconnect
+            - description: G2 decoder interconnect
+            - description: H1 encoder interconnect
+
+        interconnect-names:
+          items:
+            - const: g1
+            - const: g2
+            - const: h1

For i.MX8MP:
+        interconnects:
+          items:
+            - description: G1 decoder interconnect
+            - description: G2 decoder interconnect
+            - description: VC8000E encoder interconnect
+
+        interconnect-names:
+          items:
+            - const: g1
+            - const: g2
+            - const: vc8000e

How do you think?

Thanks,
Peng.
