Properties

Node specific properties

Properties not inherited from the base binding file.

Name

Type

Details

has-32k-erase

boolean

 
Set if the memory device supports 32 KiBy block erase operation.

readoc

string

 
Specify the number of data lines and opcode used for reading.
If not provided, 1-1-1 will be selected.

Legal values: '1-1-1', '1-1-2', '1-2-2', '1-1-4', '1-4-4'

writeoc

string

 
Specify the number of data lines and opcode used for writing.
If not provided, 1-1-1 will be selected.

Legal values: '1-1-1', '1-1-2', '1-1-4', '1-4-4'

memory-alignment

int

 
Memory alignment in bytes, used to calculate padding when performing
unaligned accesses.
If not provided, 1 byte alignment will be selected.

jedec-id

uint8-array

 
JEDEC ID as manufacturer ID, memory type, memory density

size

int

 
flash capacity in bits

sfdp-bfp

uint8-array

 
Contains the 32-bit words in little-endian byte order from the
JESD216 Serial Flash Discoverable Parameters Basic Flash
Parameters table.  This provides flash-specific configuration
information in cases were runtime retrieval of SFDP data
is not desired.

quad-enable-requirements

string

 
Quad Enable Requirements value from JESD216 BFP DW15.

Use NONE if the device detects 1-1-4 and 1-4-4 modes by the
instruction.  Use S1B6 if QE is bit 6 of the first status register
byte, and can be configured by reading then writing one byte with
RDSR and WRSR.  For other fields see the specification.

Legal values: 'NONE', 'S2B1v1', 'S1B6', 'S2B7', 'S2B1v4', 'S2B1v5', 'S2B1v6'

enter-4byte-addr

int

 
Enter 4-Byte Addressing value from JESD216 BFP DW16

This property is ignored if the device is configured to use SFDP data
from the sfdp-bfp property (CONFIG_SPI_NOR_SFDP_DEVICETREE) or to read
SFDP properties at runtime (CONFIG_SPI_NOR_SFDP_RUNTIME).

For CONFIG_SPI_NOR_SFDP_MINIMAL this is the 8-bit value from bits 31:24
of DW16 identifying ways a device can be placed into 4-byte addressing
mode.  If provided as a non-zero value the driver assumes that 4-byte
addressing is require to access the full address range, and
automatically puts the device into 4-byte address mode when the device
is initialized.

page-size

int

 
Number of bytes in a page from JESD216 BFP DW11

This property is only used in the CONFIG_SPI_NOR_SFDP_MINIMAL configuration.
It is ignored if the device is configured to use SFDP data
from the sfdp-bfp property (CONFIG_SPI_NOR_SFDP_DEVICETREE) or
if the SFDP parameters are read from the device at
runtime (CONFIG_SPI_NOR_SFDP_RUNTIME).

The default value is 256 bytes if the value is not specified.

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 “nxp,s32-qspi-nor” compatible.

Name

Type

Details

reg

array

 
register space

This property is required.

See Important properties for more information.

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

array

 
interrupts for device

See Important properties for more information.

interrupts-extended

compound

 
extended interrupt specifier for device

interrupt-names

string-array

 
name of each interrupt

interrupt-parent

phandle

 
phandle to interrupt controller node

label

string

 
Human readable string describing the device (used as device_get_binding() argument)

See Important properties for more information.

This property is deprecated.

clocks

phandle-array

 
Clock gate information

clock-names

string-array

 
name of each clock

#address-cells

int

 
number of address cells in reg property

#size-cells

int

 
number of size cells in reg property

dmas

phandle-array

 
DMA channels specifiers

dma-names

string-array

 
Provided names of DMA channel specifiers

zephyr,deferred-init

boolean

 
Do not initialize device automatically on boot. Device should be manually
initialized using device_init().

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.

zephyr,pm-device-runtime-auto

boolean

 
Automatically configure the device for runtime power management after the
init function runs.

zephyr,disabling-power-states

phandles

 
List of power states that will disable this device power.
