The auto extension is handed by the platform_deivce_alloc() API. platform_device_alloc("acp3x_i2s_playcap", PLATFORM_DEVID_AUTO); > This helps us by rectifying the renaming issue which we get by using > Platform_dev_create API`s.If we have to use platform related APIs then > we need to give different naming conventions while creating the devices > and cant use it in loop as we have 3 devices we need to call three > explicitly.This make our code lengthy. > If we use MFD it would help us a lot. > > Please suggest us how can we proceed. 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. -- Lee Jones [李琼斯] Linaro Services Technical Lead Linaro.org │ Open source software for ARM SoCs Follow Linaro: Facebook | Twitter | Blog _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx https://mailman.alsa-project.org/mailman/listinfo/alsa-devel
