If one or more bytes are 18*c67ea7d2SShubhrajyoti Datta not written, then the read operation results in an correctable error or 19*c67ea7d2SShubhrajyoti Datta uncorrectable error. 20*c67ea7d2SShubhrajyoti Datta 21*c67ea7d2SShubhrajyoti Dattaproperties: 22*c67ea7d2SShubhrajyoti Datta compatible: 23*c67ea7d2SShubhrajyoti Datta const: xlnx,zynqmp-ocmc-1.0 24*c67ea7d2SShubhrajyoti Datta 25*c67ea7d2SShubhrajyoti Datta reg: 26*c67ea7d2SShubhrajyoti Datta maxItems: 1 27*c67ea7d2SShubhrajyoti Datta 28*c67ea7d2SShubhrajyoti Datta interrupts: 29*c67ea7d2SShubhrajyoti Datta maxItems: 1 30*c67ea7d2SShubhrajyoti Datta 31*c67ea7d2SShubhrajyoti Dattarequired: 32*c67ea7d2SShubhrajyoti Datta - compatible 33*c67ea7d2SShubhrajyoti Datta - reg 34*c67ea7d2SShubhrajyoti Datta - interrupts 35*c67ea7d2SShubhrajyoti Datta 36*c67ea7d2SShubhrajyoti DattaadditionalProperties: false 37*c67ea7d2SShubhrajyoti Datta 38*c67ea7d2SShubhrajyoti Dattaexamples: 39*c67ea7d2SShubhrajyoti Datta - | 40*c67ea7d2SShubhrajyoti Datta #include <dt-bindings/interrupt-controller/arm-gic.h> 41*c67ea7d2SShubhrajyoti Datta memory-controller@ff960000 { 42*c67ea7d2SShubhrajyoti Datta compatible = "xlnx,zynqmp-ocmc-1.0"; 43*c67ea7d2SShubhrajyoti Datta reg = <0xff960000 0x1000>; 44*c67ea7d2SShubhrajyoti Datta interrupts = <GIC_SPI 10 IRQ_TYPE_LEVEL_HIGH>; 45*c67ea7d2SShubhrajyoti Datta }; 46
