-[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.

-[PATCH] eeprom_93cx6: shorten pulse timing to match spec
-
-93cx6 datasheet available here:
-
- http://ww1.microchip.com/downloads/en/DeviceDoc/21749F.pdf
-
-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.
