  	  The RTC device that will be used to (re)initialize the system
  	  clock, usually rtc0. Initialization is done when the system
  	  starts up, and when it resumes from a low power state. This
  	  device should record time in UTC, since the kernel won't do
  	  timezone correction.
  
  	  The driver for this RTC device must be loaded before late_initcall
  	  functions run, so it must usually be statically linked.
  
  	  This clock should be battery-backed, so that it reads the correct
  	  time when the system boots from a power-off state. Otherwise, your
  	  system will need an external clock source (like an NTP server).
  
  	  If the clock you specify here is not battery backed, it may still
