Properties not inherited from the base binding file.

Name	Type	Details
cs-interval-unit	int	Chip select interval units, in serial clock cycles. See the CSINTERVALUNIT field in registers FLASHA1CR0 through FLASHB2CR0. The default corresponds to the reset value of the register field. Default value: 1 Legal values: 1, 256
cs-interval	int	Minimum interval between chip select deassertion and assertion. See the CSINTERVAL field in registers FLASHA1CR0 through FLASHB2CR0. The default corresponds to the reset value of the register field.
cs-setup-time	int	Chip select setup time, in serial clock cycles. See the TCSS field in registers FLASHA1CR0 through FLASHB2CR0. The default corresponds to the reset value of the register field. Default value: 3
cs-hold-time	int	Chip select hold time, in serial clock cycles. See the TCSH field in registers FLASHA1CR0 through FLASHB2CR0. The default corresponds to the reset value of the register field. Default value: 3
data-valid-time	int	Data valid time, in nanoseconds. See the registers DLLACR through DLLBCR.
column-space	int	Column address bit width. Set to zero if the flash does not support column address. See the CAS field in registers FLASHA1CR0 through FLASHB2CR0. The default corresponds to the reset value of the register field.
word-addressable	boolean	Don't transmit the least significant address bit when the flash is word addressable. See the WA field in registers FLASHA1CR0 through FLASHB2CR0.
ahb-write-wait-unit	int	AHB write wait interval units, in AHB clock cycles. See the AWRWAITUNIT field in registers FLASHA1CR2 through FLASHB2CR2. The default corresponds to the reset value of the register field. Default value: 2 Legal values: 2, 8, 32, 128, 512, 2048, 8192, 32768
ahb-write-wait-interval	int	Time to wait between AHB triggered command sequences. See the AWRWAIT field in registers FLASHA1CR2 through FLASHB2CR2. The default corresponds to the reset value of the register field.
spi-max-frequency	int	Maximum clock frequency of device's SPI interface in Hz This property is required.
duplex	int	Duplex mode, full or half. By default it's always full duplex thus 0 as this is, by far, the most common mode. Use the macros not the actual enum value, here is the concordance list (see dt-bindings/spi/spi.h) 0 SPI_FULL_DUPLEX 2048 SPI_HALF_DUPLEX Legal values: 0, 2048
frame-format	int	Motorola or TI frame format. By default it's always Motorola's, thus 0 as this is, by far, the most common format. Use the macros not the actual enum value, here is the concordance list (see dt-bindings/spi/spi.h) 0 SPI_FRAME_FORMAT_MOTOROLA 32768 SPI_FRAME_FORMAT_TI Legal values: 0, 32768
spi-cpol	boolean	SPI clock polarity which indicates the clock idle state. If it is used, the clock idle state is logic high; otherwise, low.
spi-cpha	boolean	SPI clock phase that indicates on which edge data is sampled. If it is used, data is sampled on the second edge; otherwise, on the first edge.
spi-hold-cs	boolean	In some cases, it is necessary for the master to manage SPI chip select under software control, so that multiple spi transactions can be performed without releasing it. A typical use case is variable length SPI packets where the first spi transaction reads the length and the second spi transaction reads length bytes.
supply-gpios	phandle-array	GPIO specifier that controls power to the device. This property should be provided when the device has a dedicated switch that controls power to the device. The supply state is entirely the responsibility of the device driver. Contrast with vin-supply.
vin-supply	phandle	Reference to the regulator that controls power to the device. The referenced devicetree node must have a regulator compatible. This property should be provided when device power is supplied by a shared regulator. The supply state is dependent on the request status of all devices fed by the regulator. Contrast with supply-gpios. If both properties are provided then the regulator must be requested before the supply GPIOS is set to an active state, and the supply GPIOS must be set to an inactive state before releasing the regulator.
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.
erase-block-size	int	address alignment required by flash erase operations
write-block-size	int	address alignment required by flash write operations
