The reg property describes two register blocks: one for the memory corresponding to the QSPI peripheral registers, and another for the memory mapped XIP area: qspi: qspi@2b000 { compatible = "nordic,nrf-qspi"; reg = <0x2b000 0x1000>, <0x10000000 0x10000000>; reg-names = "qspi", "qspi_mm"; ... }; Above, the register block with base address 0x2b000 and name "qspi" are the QSPI peripheral registers. The register block with base address 0x10000000 and name "qspi_mm" is the XIP area. compatible: "nordic,nrf-qspi" include: [flash-controller.yaml, pinctrl-device.yaml] bus: qspi properties: "#address-cells": required: true const: 1 "#size-cells": required: true const: 0 interrupts: required: true pinctrl-0: required: true
