Sorry for the delay in reply, Mar 1st was the holiday.
I thought of two solutions.

1. squash the patches in a single patch

2. split the dts related patches so that the first part adds the:
+    samsung,burst-clock-frequency = <512000000>;
+    samsung,esc-clock-frequency = <16000000>;

and the second part at the end removes the 'port' node
So it consists of 6 patches in total.

Which do you think is better?
If you have any other ideas, could you tell me?

Hoegeun
