i2c-gpio

[yuanwei2088]

hi,all

I am porting a new ril device for a new phone,which is using  i2-gpio module .

now ,i create platform device i2c-gpio as follow:

 

and  in  sys/bus/i2c/   there is not the new bus for me,

 

in board.c

static struct i2c_gpio_platform_data i2c3_data = { 

        .sda_pin = 37, //col5 sda 37

        .scl_pin = 38, //kcol4 scl 38

        .udelay = 5,         

        .sda_is_open_drain = 1, //1

        .scl_is_open_drain = 1, //1

       

 

}; 

 

static struct platform_device i2c3_device = { 

        .name           = "i2c-gpio", 

        .id             = 2, 

        .dev = { 

                .platform_data=&i2c3_data, 

        }, 

 

};

but when booting kernel, a error happens , below is it!

 

any helps will be gratefull。。。。。。。。。。。

check i2c-gpio 's probe function for more information.

是的 查下probe函数，看看那步失败了。
