Freescale LS1021A SoC-specific Device Tree Bindings
-------------------------------------------
Freescale SCFG
SCFG is the supplemental configuration unit, that provides SoC specific
configuration and status registers for the chip. Such as getting PEX port
status.
Required properties:
- compatible: should be "fsl,ls1021a-scfg"
- reg: should contain base address and length of SCFG memory-mapped registers
Example:
scfg: scfg@1570000 {
compatible = "fsl,ls1021a-scfg";
reg = <0x0 0x1570000 0x0 0x10000>;
};
Freescale DCFG
DCFG is the device configuration unit, that provides general purpose
configuration and status for the device. Such as setting the secondary
core start address and release the secondary core from holdoff and startup.
Required properties:
- compatible: should be "fsl,ls1021a-dcfg"
- reg : should contain base address and length of DCFG memory-mapped registers
Example:
dcfg: dcfg@1ee0000 {
compatible = "fsl,ls1021a-dcfg";
reg = <0x0 0x1ee0000 0x0 0x10000>;
};
