I think i solve it using
static struct i2c_board_info __initdata inv_mpu_i2c2_board_info[] = {
{
I2C_BOARD_INFO("mpu9150", 0x69),
/*.irq = MPU_IRQ,*/
.platform_data = &mpu_gyro_data,
},
{
I2C_BOARD_INFO("ak8975", 0x0E),
.platform_data = &mpu_compass_data,
},
};
static void __init sun7i_init(void)
{
pr_info("%s: enter\n", __func__);
sw_pdev_init();
i2c_register_board_info(2, __rtc_i2c_board_info,
ARRAY_SIZE(__rtc_i2c_board_info));
inv_mpu_i2c2_board_info[0].irq = __gpio_to_irq(176);
i2c_register_board_info(2, inv_mpu_i2c2_board_info,
ARRAY_SIZE(inv_mpu_i2c2_board_info));
}
