+[PATCH] eeprom_93cx6: Add comment for 1us delay after pulse
+
+This will add a comment for the 1us delay which is taken
+after the pulse has been switched. The 1us delay is based
+on the specifications so that should be made clear.

+
+Figure 1-1 and Table 1-2 on pages 4-5 indicate that both Clock High
+Time and Clock Low Time have largest minimum times of 450ns.
