1* STMP3xxx/i.MX28 Time Clock controller 2 3Required properties: 4- compatible: should be one of the following. 5 * "fsl,stmp3xxx-rtc" 6- reg: physical base address of the controller and length of memory mapped 7 region. 8- interrupts: rtc alarm interrupt 9 10Optional properties: 11- stmp,crystal-freq: override crystal frequency as determined from fuse bits. 12 Only <32000> and <32768> are possible for the hardware. Use <0> for 13 "no crystal". 14 15Example: 16 17rtc@80056000 { 18 compatible = "fsl,imx28-rtc", "fsl,stmp3xxx-rtc"; 19 reg = <0x80056000 2000>; 20 interrupts = <29>; 21}; 22
