Subject: [PATCH] eeprom_93cx6: Add comment for 1us delay after pulse
X-Git-Tag: v2.6.23-rc1~1201^2~73

[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.
