That the syntax is dev_err_probe() or that you do not have clocks?

Really?

Point me to the line in your patch:

+properties:
+  compatible:
+    enum:
+      - sophgo,cv1800b-rtc
+  reg:
+    maxItems: 1
+
+  interrupts:
+    maxItems: 1
+
+required:
+  - compatible
+  - reg
+  - interrupts

Where are the clocks?


Best regards,
Krzysztof
