    Subject[RESEND PATCH v5 3/4] dt-bindings: misc: tmr-inject: Add device-tree binding for TMR Inject
    Date
    The Triple Modular Redundancy(TMR) Inject core provides functional fault
    injection by changing selected MicroBlaze instructions, which provides the
    possibility to verify that the TMR subsystem error detection and fault
    recovery logic is working properly.
