Dear all
Now I'm creating SuperH board code.
and I2C-RTC driver probe function isn't called in boot.
other I2C devices (I2C-camera) works well for me.
my I2C busses is i2c-sh_mobile.c
I would like to use r2025sd RTC which is attached
to I2C1 on my board.
What should I do ?
where should I check ?
Now I'm doing...

/* I2C device */
static struct i2c_board_info i2c1_devices[] = {
{
I2C_BOARD_INFO("r2025sd", 0x32),

static int __init devices_setup(void)
{
...
/* enable I2C1 device */
i2c_register_board_info(1, i2c1_devices,
ARRAY_SIZE(i2c1_devices));
...
}
device_initcall(devices_setup);
