title: Kryo EDAC(Error Detection and Correction) node binding

description: |+
  Kryo EDAC node is defined to describe on-chip error detection and correction
  for the Kryo core.

  Kryo 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 ECC mechanism is based on interrupts.
  The following section describes the DT node binding for kryo_cpu_erp.

properties:
  compatible:
      const: arm,arm64-kryo-cpu-erp
      description:
        Implements cache error detection and correction for Kryo CPUs.

  interrupts:
    description: Interrupt-specifier for L1/L2, L3/SCU error IRQ(s)

  interrupt-names:
    description: Descriptive names of the interrupts

required:
  - compatible
  - interrupts
  - interrupt-names

examples:
  - |
    kryo-erp {
      compatible = "arm,arm64-kryo-cpu-erp";
      interrupts = <GIC_PPI 6 IRQ_TYPE_LEVEL_HIGH>,
        <GIC_PPI 7 IRQ_TYPE_LEVEL_HIGH>,
        <GIC_SPI 34 IRQ_TYPE_LEVEL_HIGH>,
        <GIC_SPI 35 IRQ_TYPE_LEVEL_HIGH>;

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