Hi Rafel,
The fex file i have attached in my previous post i did not done any
changes.
and here my machine driver .
in device.c file just add fallowing line.
+static struct i2c_board_info __initdata aic3x_i2c_board_info[] = {
+ {
+ .type = "tlv320aic31xx",
+ .addr = 0x18,
+ }
+};
void __init sw_pdev_init(void)
{
platform_add_devices(sw_pdevs, ARRAY_SIZE(sw_pdevs));
+ i2c_register_board_info(2, aic3x_i2c_board_info,
+ ARRAY_SIZE(aic3x_i2c_board_info));
}
which kernel you are using?.
Regards
Punith
