+title: PWM Tach controller

+description: |

+properties:
+  compatible:
+    items:
+      - enum:
+          - aspeed,ast2600-pwm-tach
+      - const: syscon
+      - const: simple-mfd
+
+  reg:
+    maxItems: 1
+
+  clocks:
+    maxItems: 1
+
+  resets:

If this is simple-mfd then it cannot take clocks or resets.  Usually the
recommendation for such case is: This is not simple-mfd, drop it. Drop
also syscon and make a proper device.

However I am surprised to see such change, so I have no clue why this
was done.

Actually now I see it was like that in previous patch, I just missed it
during previous review. Anyway this must be fixed.

Best regards,
Krzysztof
