	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)
	Does a SPI device have a chip select line configured?
#define	DT_SPI_DEV_CS_GPIOS_CTLR(spi_dev)
	Get a SPI device's chip select GPIO controller's node identifier.
#define	DT_SPI_DEV_CS_GPIOS_PIN(spi_dev)
	Get a SPI device's chip select GPIO pin number.
#define	DT_SPI_DEV_CS_GPIOS_FLAGS(spi_dev)
	Get a SPI device's chip select GPIO flags.
#define	DT_INST_SPI_DEV_HAS_CS_GPIOS(inst)
	Equivalent to DT_SPI_DEV_HAS_CS_GPIOS(DT_DRV_INST(inst)).
