Each partition must have its + relative offset and size specified. Depending on partition function extra + properties can be used. + + A partition may be dynamically allocated by a specific parser at runtime. + In this specific case, a specific suffix is required to the node name. + Everything after 'partition-' will be used as the partition name to compare + with the one dynamically allocated by the specific parser. + If the partition contains invalid char a label can be provided that will + be used instead of the node name to make the comparison. + This is used to assign an OF node to the dynamiccally allocated partition + so that subsystem like NVMEM can provide an OF node and declare NVMEM cells. + The OF node will be assigned only if the partition label declared match the + one assigned by the parser at runtime. + +maintainers: + - Rafał Miłecki <rafal@milecki.pl> + +properties: + reg: + description: partition's offset and size within the flash + maxItems: 1 + + label: + description: The label / name for this partition.
