3*4882a593SmuzhiyunSCFG is the supplemental configuration unit, that provides SoC specific
4*4882a593Smuzhiyunconfiguration and status registers for the chip. Such as getting PEX port
5*4882a593Smuzhiyunstatus.
6*4882a593Smuzhiyun
7*4882a593SmuzhiyunRequired properties:
8*4882a593Smuzhiyun  - compatible: Should contain a chip-specific compatible string,
9*4882a593Smuzhiyun	Chip-specific strings are of the form "fsl,<chip>-scfg",
10*4882a593Smuzhiyun	The following <chip>s are known to be supported:
11*4882a593Smuzhiyun	ls1012a, ls1021a, ls1043a, ls1046a, ls2080a.
12*4882a593Smuzhiyun
13*4882a593Smuzhiyun  - reg: should contain base address and length of SCFG memory-mapped registers
14*4882a593Smuzhiyun
15*4882a593SmuzhiyunExample:
16*4882a593Smuzhiyun	scfg: scfg@1570000 {
17*4882a593Smuzhiyun		compatible = "fsl,ls1021a-scfg";
18*4882a593Smuzhiyun		reg = <0x0 0x1570000 0x0 0x10000>;
19*4882a593Smuzhiyun	};
