1 * Real Time Clock of the i.MX SoCs
2
3 RTC controller for the i.MX SoCs
4
5 Required properties:
6 - compatible: Should be "fsl,imx1-rtc" or "fsl,imx21-rtc".
7 - reg: physical base address of the controller and length of memory mapped
8   region.
9 - interrupts: IRQ line for the RTC.
10 - clocks: should contain two entries:
11   * one for the input reference
12   * one for the the SoC RTC
13 - clock-names: should contain:
14   * "ref" for the input reference clock
15   * "ipg" for the SoC RTC clock
