SPI driver issue in Linux kernel3.0.8 ~

Hi Guys,

I want add a SPI driver in Linux kernel3.0.8 on my Panda,and i use below functions in board_omap4panda.c file:

static struct tommy_spi_platform_data tommy_spi_pdata __initdata =

{

.oe_gpio = TOMMY_SPI_OUTPUT_ENABLE,

.oe_inverted = 1,

.pwr_gpio = TOMMY_SPI_PWR,

.irq_flags = 0 / use default flags in the driver /

};

static struct spi_board_info tommy_spi_devices[] __initdata = {

{

.modalias = "tommy_spi",

.bus_num = 1, //use spi1 bus

.chip_select = 0,

.mode = SPI_MODE_0,

.max_speed_hz = 10000000,

.platform_data = &tommy_spi_pdata,

.irq = 0, / will be calculated later /

},

};

static void __init register_tommy_spi_devices(void)

{

printk("<0>" "Tommy:In the function: %s!!!n", FUNCTION);

tommy_spi_devices[0].irq = gpio_to_irq(TOMMY_SPI_INT);

spi_register_board_info(tommy_spi_devices, ARRAY_SIZE(tommy_spi_devices));

}

static void __init omap4_panda_init(void)

{

......

omap4_panda_display_init();

printk("<0>""Tommy SPI Driver Register~");

init_tommy_mux_io(); //add for tommy tp control gpio init

register_tommy_spi_devices();

if (cpu_is_omap446x())

{

......

}

This method is OK in linux kernel2.6.35,but linux kernel3.0.8. I registered SPI driver successfuly ,but when i test the SPI signal use oscilloscope,there is no SPI signal out like CLK ,SIMO. But all signal out is OK in kernel2.6.35.

What is the problem?Please help me ~

Thanks

Tommy
