- Simplify the message passing between readclock and the driver.
- Add a -q command line option to suppress warning messages. This
cuts down on the noise when readclock is called early in the boot
sequence and a secondary RTC driver (ex TPS95650) isn't up yet.
- Update the man page to be less i386 centric and add details about
the new -q option.
