Please use subject prefixes matching the subsystem. You can get them for
example with `git log --oneline -- DIRECTORY_OR_FILE` on the directory
your patch is touching.


Isn't spi the right subsystem here?

+    fsi2spi@1c00 {
+        compatible = "ibm,fsi2spi";
+        reg = <0x1c00 0x400>;
+        #address-cells = <1>;
+        #size-cells = <0>;
Use rather some simple wrapper instead of node causing warnings, e.g.
fsi {} with only address/size cells.


Will do, thanks.





Best regards,
Krzysztof
