1*4882a593Smuzhiyun* STMP3xxx/i.MX28 Time Clock controller
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunRequired properties:
4*4882a593Smuzhiyun- compatible: should be one of the following.
5*4882a593Smuzhiyun    * "fsl,stmp3xxx-rtc"
6*4882a593Smuzhiyun- reg: physical base address of the controller and length of memory mapped
7*4882a593Smuzhiyun  region.
8*4882a593Smuzhiyun- interrupts: rtc alarm interrupt
9*4882a593Smuzhiyun
10*4882a593SmuzhiyunOptional properties:
11*4882a593Smuzhiyun- stmp,crystal-freq: override crystal frequency as determined from fuse bits.
12*4882a593Smuzhiyun  Only <32000> and <32768> are possible for the hardware.  Use <0> for
13*4882a593Smuzhiyun  "no crystal".
