* Kryo 3xx EDAC node

Kryo3xx EDAC node is defined to describe on-chip error detection and correction
for the Kryo3xx core.

Kryo3xx will report all SBE and DBE found in L1/L2/L3/SCU caches in two registers:
	ERRXSTATUS - Error Record Primary Status Register
	ERRXMISC0 - Error Record Miscellaneous Register

Current implementation of Kryo 3xx ECC mechanism does not have interrupts setup,
and so requires polling of the registers to check if a error has been reported.

The following section describes the DT node binding for kryo_3xx_cpu_erp.

Required properties:
- compatible		: Shall be "arm,arm64-kryo3xx-cpu-erp".
- interrupts		: Interrupt-specifier for L1/L2, L3/SCU error IRQ(s)
- interrupt-names	: Descriptive names of the interrupts

Example:

	kryo3xx-erp {
		compatible = "arm,arm64-kryo3xx-cpu-erp";
		interrupts = <1 6 4>,
			<1 7 4>,
			<0 34 4>,
			<0 35 4>;

		interrupt-names = "l1-l2-faultirq",
				"l1-l2-errirq",
				"l3-scu-errirq",
				"l3-scu-faultirq";
	};
