+    The `to_ptr` operation casts a ptr-like object to a `!ptr.ptr`. It's
+    important to note that:
+    - The ptr-like object cannot be a `!ptr.ptr`.
+    - The memory-space of both the `ptr` and ptr-like object must match.
+    - The cast is side-effect free.
+
+    Example:
+
+    ```mlir
+    %ptr0 = ptr.to_ptr %my_ptr : !my.ptr<f32, 0> -> !ptr.ptr<0>
+    %ptr1 = ptr.to_ptr %memref : memref<f32, 0> -> !ptr.ptr<0>
+    ```
+  }];

Yes, those are coming in a later patch. This one only deals between ptr and ptrLike conversions.
