Changes in v4: * Changed the type of properties to uint64-arrays in order to be able to describe the size of each element in the array. * Updated the example accordingly. Changes in v3: * Rebased on top of Pratyush's recent changes. * Dropped the commit allowing to provide two reg entries on the node name. * Dropped the commit referencing spi-controller.yaml from jedec,spi-nor.yaml, now replaced by spi-peripheral-props.yaml and already done in Pratyush's series. * Added Rob's Ack. * Enhanced a commit message. * Moved the new properties to the new SPI peripheral binding file. Changes in v2: * Dropped the dtc changes for now. * Moved the properties in the device's nodes, not the controller's. * Dropped the useless #address-cells change. * Added a missing "minItems". * Moved the new properties in the spi-controller.yaml file. * Added an example using two stacked memories in the spi-controller.yaml file. * Renamed the properties to drop the Xilinx prefix. * Added a patch to fix the spi-nor jedec yaml file.
