linux spi 设备驱动简析 二(基于s5pv210)

三:spi设备driver

在板文件中添加spi设备

static struct spi_board_info s3c_spi_devs[] __initdata 
	
       [0] = {
		.modalias        = "spidev",	/* device node name */
		.mode            = SPI_MODE_0,	/* CPOL=0, CPHA=0 */
		.max_speed_hz    = 10000000,
		/* Connected to SPI-1 as 1st Slave */
		.bus_num         = 1,
		.irq             = IRQ_SPI1,
		.chip_select     = 0,
		.controller_data = &smdk_spi1_csi[SMDK_MMCSPI_CS],
	},
}static struct
