Each partition must have its 11 relative offset and size specified. Depending on partition function extra 12 properties can be used. 13 14 A partition may be dynamically allocated by a specific parser at runtime. 15 In this specific case, a specific suffix is required to the node name. 16 Everything after 'partition-' will be used as the partition name to compare 17 with the one dynamically allocated by the specific parser. 18 If the partition contains invalid char a label can be provided that will 19 be used instead of the node name to make the comparison. 20 This is used to assign an OF node to the dynamiccally allocated partition 21 so that subsystem like NVMEM can provide an OF node and declare NVMEM cells. 22 The OF node will be assigned only if the partition label declared match the 23 one assigned by the parser at runtime. 24 25maintainers: 26 - Rafał Miłecki <rafal@milecki.pl> 27 28properties: 29 reg: 30 description: partition's offset and size within the flash 31 maxItems: 1 32 33 label: 34 description: The label / name for this partition.
