Vendor: NXP Semiconductors

Note

An implementation of a driver matching this compatible is available in drivers/flash/flash_nxp_s32_qspi_nor.c.

Description

QSPI NOR flash connected to the NXP S32 QSPI bus.

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.
