Subject: [PATCH] dt-bindings: misc: tmr-inject: Add device-tree binding for
TMR Inject
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.
