In RK3288, there are two eFuse. One is organized as 32bits by 8 one-time 
programmable
electrical fuses with random access interface, and the other is organized as 
32bits by 32
one-time programmable electrical fuses.
The 32x32 eFuse can only be accessed by APB bus when IO_SECURITYsel is high.

+
+Required properties:
+- compatible : should be:

+- reg: Should contain 1 entry: the entry gives the physical address and length
+       of the fuse registers.
+
+Example:
+
+       efuse: efuse@ffb40000 {
+               compatible = "rockchip,rk3288-efuse";
