John,
I'm looking at
wandboard-sdk-20130208/linux-3.0.35-imx6-wand/arch/arm/mach-mx6/board-wand.c
Code:
--------------------
/****************************************************************************
*
* SPI - while not used on the Wandboard, the pins are routed out
*
****************************************************************************/
static const __initdata iomux_v3_cfg_t wand_spi_pads[] = {
MX6DL_PAD_EIM_D16__ECSPI1_SCLK,
MX6DL_PAD_EIM_D17__ECSPI1_MISO,
MX6DL_PAD_EIM_D18__ECSPI1_MOSI,
MX6DL_PAD_EIM_EB2__GPIO_2_30,
MX6DL_PAD_EIM_CS0__ECSPI2_SCLK,
MX6DL_PAD_EIM_CS1__ECSPI2_MOSI,
MX6DL_PAD_EIM_OE__ECSPI2_MISO,
MX6DL_PAD_EIM_RW__GPIO_2_26,
MX6DL_PAD_EIM_LBA__GPIO_2_27,
};
/* The choice of using gpios for chipselect is deliberate,
there can be issues using the dedicated mux modes for cs.
*/
/* ------------------------------------------------------------------------ */
static const int wand_spi1_chipselect[] = { IMX_GPIO_NR(2, 30) };
/* platform device */
static const struct spi_imx_master wand_spi1_data = {
.chipselect = wand_spi1_chipselect,
.num_chipselect = ARRAY_SIZE(wand_spi1_chipselect),
};
/* ------------------------------------------------------------------------ */
static const int wand_spi2_chipselect[] = { IMX_GPIO_NR(2, 26),
IMX_GPIO_NR(2, 27) };
static const struct spi_imx_master wand_spi2_data = {
.chipselect = wand_spi2_chipselect,
.num_chipselect = ARRAY_SIZE(wand_spi2_chipselect),
};
/* ------------------------------------------------------------------------ */
static void __init wand_init_spi(void) {
WAND_SETUP_PADS(wand_spi_pads);
imx6q_add_ecspi(0, &wand_spi1_data);
imx6q_add_ecspi(1, &wand_spi2_data);
}
--------------------
This is the setup I think for the 2x SPI routed over the EDM connector.
What are you after? A node under /dev so you can use one of them?
