nordic,nrf-qspi

Vendor: Nordic Semiconductor

Description

These nodes are “qspi” bus nodes.

Properties defining the interface for the Nordic QSPI peripheral.

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.
