New Revision: 322282
URL: https://svnweb.freebsd.org/changeset/base/322282

Log:
  Remove the ds133x and s35390a i2c RTC drivers for now.  They both do i2c
  transfers in their probe() or attach() routines, and that doesn't work
  when the low-level controller requires interrupts to be functional.
  
  The DS133x family of chips is nearly identical to the DS1307 and support
  for them should be added to that driver, then the ds133x driver can be
  deleted.  The s35390a driver just needs a non-trivial workover.  In both
  cases that work will be done and committed separately.
