+* Andestech Processor Binding
+
+This binding specifies what properties must be available in the device tree
+representation of a Andestech Processor Core, which is the root node in the
+tree.
+
+Required properties:
+
+       - compatible:
+               Usage: required
+               Value type: <string>
+               Definition: should be one of:
+                       "andestech,n13"
+                       "andestech,n15"
+                       "andestech,d15"
+                       "andestech,n10"
+                       "andestech,d10"
+                       "andestech,nds32v3"

Based on https://lkml.org/lkml/2017/11/27/1290, this should say that
the device tree should always list 'andestech,nds32v3' as the most
generic 'compatible' value and list exactly one of the others in
addition.

Hi, Arnd:

I will remove the others and just left "andestech,nds32v3" in here.
