The auto extension is handed by the platform_deivce_alloc() API.
platform_device_alloc("acp3x_i2s_playcap", PLATFORM_DEVID_AUTO);

You have 2 choices available to you based on whether your device is an MFD or not:
If yes, move it (or a part of it) to drivers/mfd. If no, then use the platform_device_*() API.
