linux-2.6.29 i have a s3c2440 board .i "make menuconfig" to enable the spi core and spi user mode driver i get a error "no platform data supllied" so i "google" and find the code ////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// in the kernel 2.6.22 "static struct spi_board_info s3c2410_spi_board[] = { [0] = { .modalias = "s3c2410_spi", .platform_data = NULL, .irq = IRQ_EINT1, .chip_select = 0, .max_speed_hz = 4000*1000, }, }; static struct s3c2410_spi_info s3c2410_spi_platdata = { .pin_cs = S3C2410_GPG2, .board_info = s3c2410_spi_board, .board_size = ARRAY_SIZE(s3c2410_spi_board), }; /* end add */ static struct resource s3c_spi0_resource[] = { [0] = { .start = S3C24XX_PA_SPI, .end = S3C24XX_PA_SPI + 0x1f, .flags = IORESOURCE_MEM, }, [1] = { .start = IRQ_SPI0, .end = IRQ_SPI0, .flags = IORESOURCE_IRQ, } }; static u64 s3c_device_spi0_dmamask = 0xffffffffUL; struct platform_device s3c_device_spi0 = { .name = "s3c2410-spi", .id = 0, .num_resources = ARRAY_SIZE(s3c_spi0_resource), .resource = s3c_spi0_resource, .dev = { .dma_mask = &s3c_device_spi0_dmamask, .coherent_dma_mask = 0xffffffffUL, /* add by lfc */ .platform_data = &s3c2410_spi_platdata, /* end add */ } }; EXPORT_SYMBOL(s3c_device_spi0);" //////////////////////////////////////////////////////////////////////////////////////////////////// but i found that in the kernel 2.6.29 the struct s3c2410_spi_info is different from the kernel 2.6.22 so i cant add the above codes to linux-2.6.29 and how can i do it !!!
