nordic,nrf-qspi¶

Description¶

These nodes are “qspi” bus nodes.

Properties defining the interface for the Nordic QSPI peripheral.

Properties¶

Node specific properties

Properties not inherited from the base binding file.

Details

sck-pin

int

The SCK pin to use.

For pins P0.0 through P0.31, use the pin number. For example,
to use P0.16 for SCK, set:

    sck-pin = <16>;

For pins P1.0 through P1.31, add 32 to the pin number. For
example, to use P1.2 for SCK, set:

    sck-pin = <34>;  /* 32 + 2 */

This property is required.

io-pins

array

Pin numbers associated with IO0 through IO3 signals.

Examples:

    io-pins = <io0-pin io1-pin>; // two pins

    io-pins = <io0-pin io1-pin io2-pin io3-pin>; // four pins

Either two or four pins must be configured using this property
as shown above. The pin numbering scheme is the same as the
sck-pin property's.

This property is required.

csn-pins

array

Chip select signal pin number. Exactly one pin should be
given. The pin numbering scheme is the same as the
sck-pin property's.

This property is required.

Deprecated node specific properties

Deprecated properties not inherited from the base binding file.

(None)

Base properties

Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “nordic,nrf-qspi” compatible.

Name	Type	Details
`#address-cells`	`int`	number of address cells in reg property This property is required. Constant value: `1`
`#size-cells`	`int`	number of size cells in reg property This property is required.
`interrupts`	`array`	interrupts for device This property is required. See Important properties for more information.
`label`	`string`	Human readable string describing the device (used as device_get_binding() argument) This property is required. See Important properties for more information.
`reg`	`array`	register space This property is required. See Important properties for more information.
`status`	`string`	indicates the operational status of a device Legal values: `'ok'`, `'okay'`, `'disabled'`, `'reserved'`, `'fail'`, `'fail-sss'` See Important properties for more information.
`compatible`	`string-array`	compatible strings This property is required. See Important properties for more information.
`reg-names`	`string-array`	name of each register space
`interrupts-extended`	`compound`	extended interrupt specifier for device
`interrupt-names`	`string-array`	name of each interrupt
`interrupt-parent`	`phandle`	phandle to interrupt controller node
`clocks`	`phandle-array`	Clock gate information
`clock-names`	`string-array`	name of each clock
`dmas`	`phandle-array`	DMA channels specifiers
`dma-names`	`string-array`	Provided names of DMA channel specifiers
`io-channels`	`phandle-array`	IO channels specifiers
`io-channel-names`	`string-array`	Provided names of IO channel specifiers
`wakeup-source`	`boolean`	Property to identify that a device can be used as wake up source. When this property is provided a specific flag is set into the device that tells the system that the device is capable of wake up the system. Wake up capable devices are disabled (interruptions will not wake up the system) by default but they can be enabled at runtime if necessary.
