Converted MSM58321 to DEVCB2, uses level logic rather than edge detection for strobes (as per datasheet), added nvram interface as there are some configuration bits to save, added support for 12 and 24 hour. It defaults to 12 hour, but you can configure it in the driver to default to 24H. You can configure what year 0 is in the driver, which is used when setting the date at startup. [smf]
