      1 Motorola mc146818 compatible RTC
      2~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      3
      4Required properties:
      5  - compatible : "motorola,mc146818"
      6  - reg : should contain registers location and length.
      7
      8Optional properties:
      9  - interrupts : should contain interrupt.
     10  - ctrl-reg : Contains the initial value of the control register also
     11    called "Register B".
     12  - freq-reg : Contains the initial value of the frequency register also
     13    called "Regsiter A".
     14
     15"Register A" and "B" are usually initialized by the firmware (BIOS for
     16instance). If this is not done, it can be performed by the driver.

     18ISA Example:
     19
     20	rtc@70 {
     21	         compatible = "motorola,mc146818";
     22	         interrupts = <8 3>;
     23	         interrupt-parent = <&ioapic1>;
     24	         ctrl-reg = <2>;
     25	         freq-reg = <0x26>;
     26	         reg = <1 0x70 2>;
     27	 };
