+Subject: [PATCH] clk: sunxi: support better factor DT nodes
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The DT nodes should look like
+
+    abc_clk: clk@deadbeef {
+        ...
+        clock-output-names = "abc";
+    }
+
+But our old DT nodes look like
+
+    abc: abc@deadbeef {
+        ...
+    }
+
+So, let's support both formats, until we can transition everything
+to the new, correct one.
