Re: [PATCH 1/2] dt-bindings: edac: Add DT bindings for Kryo EDAC

This adds DT bindings for Kryo EDAC implemented with RAS
extensions on KRYO{3,4}XX CPU cores for reporting of cache
errors.

+description: |
+  Kryo EDAC is defined to describe on-chip error detection and correction
+  for the Kryo CPU cores which implement RAS extensions. It will report
+  all Single Bit Errors and Double Bit Errors found in L1/L2 caches in
+  in two registers ERXSTATUS_EL1 and ERXMISC0_EL1. L3-SCU cache errors
+  are reported in ERR1STATUS and ERR1MISC0 registers.
+    ERXSTATUS_EL1 - Selected Error Record Primary Status Register, EL1
+    ERXMISC0_EL1 - Selected Error Record Miscellaneous Register 0, EL1
+    ERR1STATUS - Error Record Primary Status Register
+    ERR1MISC0 - Error Record Miscellaneous Register 0
+  Current implementation of Kryo ECC(Error Correcting Code) mechanism is
+  based on interrupts.
