Hi,
I got OMAP-L138 EVM and I'm running kernel v2.6.34
from khilman/linux-davinci.git and I would like to try the SPI patch. I
successfully applied the patch to the driver, and now I'm trying to modify
platform data in board-da850-evm.c. I added the following lines :
#include <mach/spi.h>
[...]
static struct davinci_spi_config spidev_cfg = {
.parity_enable = 0,
.intr_level = 0,
.io_type = SPI_IO_TYPE_DMA,
.wdelay = 0,
.timer_disable = 1,
};
static struct spi_board_info da850_spi_board_info[] = {
[0] = {
.modalias = "spidev",
.controller_data = &spidev_cfg,
.mode = SPI_MODE_0,
.max_speed_hz = 10000000,
.bus_num = 1,
.chip_select = 1,
},
};
[...]
static __init void da850_evm_init(void)
{
int ret;
[...]
ret = davinci_cfg_reg_list(da850_spi1_pins);
if (ret)
pr_warning("da850_evm_init: spi1 mux setup failed: %d\n", ret);
da850_init_spi1(NULL, 2, da850_spi_board_info,
ARRAY_SIZE(da850_spi_board_info));
[...]
}
I do not see spidev1.1 in /dev. Any clue?
Thank you.
Regards,
Nicolas
