iiuc from the link ds1339 ds, the register configuration is enabling
internal diodes and resistors for the trickle charge configuration.  I
may have read it incorrectly, though.

In either case, my main point was to prepend 'trickle-' to the property
to more accurately describe what it is toggling.
