Modified Files:
src/sys/dev/i2c: ds1307.c
Log Message:
More cleanup to i2c autoconfiguration:
- Get all of the drivers onto the new match quality constants.
- Introduce a new helper function, iic_use_direct_match(), that has
all of the logic for direct-config matching. If it returns true,
the driver returns the match result (which may be 0). If it returns
false, the driver does indirect-config matching.
- iic_compat_match() now returns a weighted match quality; matches to
lower-indexed "compatible" device property are more-specific matches,
and return a better match quality accordingly.
In addition to the above:
- Add support for direct-config matching this driver based on
"compatible" properties.
- Address-only matching is now done based on the specific addresses
the requested model supports.
- "compatible" property can specify to the driver which model is to
be used, so that using config "flags" directives aren't required
in the direct-config case.
XXX More changes coming that require re-factoring some other code.
