Macros
#define	DT_SPI_HAS_CS_GPIOS(spi)   DT_NODE_HAS_PROP(spi, cs_gpios)
	Does a SPI controller node have chip select GPIOs configured?
#define	DT_SPI_NUM_CS_GPIOS(spi)
	Number of chip select GPIOs in a SPI controller's cs-gpios property.
#define	DT_SPI_DEV_HAS_CS_GPIOS(spi_dev)   DT_SPI_HAS_CS_GPIOS(DT_BUS(spi_dev))
	Does a SPI device have a chip select line configured? Example devicetree fragment:
#define	DT_SPI_DEV_CS_GPIOS_CTLR(spi_dev)    DT_GPIO_CTLR_BY_IDX(DT_BUS(spi_dev), cs_gpios, DT_REG_ADDR(spi_dev))
	Get a SPI device's chip select GPIO controller's node identifier.
#define	DT_SPI_DEV_CS_GPIOS_PIN(spi_dev)    DT_GPIO_PIN_BY_IDX(DT_BUS(spi_dev), cs_gpios, DT_REG_ADDR(spi_dev))
	Get a SPI device's chip select GPIO pin number.
#define	DT_SPI_DEV_CS_GPIOS_FLAGS(spi_dev)    DT_GPIO_FLAGS_BY_IDX(DT_BUS(spi_dev), cs_gpios, DT_REG_ADDR(spi_dev))
	Get a SPI device's chip select GPIO flags.
#define	DT_INST_SPI_DEV_HAS_CS_GPIOS(inst)    DT_SPI_DEV_HAS_CS_GPIOS(DT_DRV_INST(inst))
	Equivalent to DT_SPI_DEV_HAS_CS_GPIOS(DT_DRV_INST(inst)).
#define	DT_INST_SPI_DEV_CS_GPIOS_CTLR(inst)    DT_SPI_DEV_CS_GPIOS_CTLR(DT_DRV_INST(inst))
	Get GPIO controller node identifier for a SPI device instance This is equivalent to DT_SPI_DEV_CS_GPIOS_CTLR(DT_DRV_INST(inst)).
#define	DT_INST_SPI_DEV_CS_GPIOS_PIN(inst)    DT_SPI_DEV_CS_GPIOS_PIN(DT_DRV_INST(inst))
	Equivalent to DT_SPI_DEV_CS_GPIOS_PIN(DT_DRV_INST(inst)).
#define	DT_INST_SPI_DEV_CS_GPIOS_FLAGS(inst)    DT_SPI_DEV_CS_GPIOS_FLAGS(DT_DRV_INST(inst))
	DT_SPI_DEV_CS_GPIOS_FLAGS(DT_DRV_INST(inst)).
