Since this appears to be memory mapped in your case, it does not sound
like "serdes-10g" alone is going to be sufficient, should not we have a
SoC specific compatible string if nothing else?

+  reg-names:

You would also need to describe how many of these two properties are
expected.

+  little-endian:

This is redundant with the default binding then, and if it is not
already in the common YAML binding, can you please add little-endian and
native-endian added there?

+examples:

+    serdes1: serdes@1ea0000 {
+        compatible = "serdes-10g";
+        reg = <0x0 0x1ea0000 0 0x00002000>;
