I mean, the main goal of those MEDIA_*_SUPPORT is to make simpler for the users to select a subset of the drivers. Those options actually make visible the corresponding entries for pci/usb/... drivers. So, for example, drivers/media/usb/Kconfig contains: if MEDIA_CAMERA_SUPPORT comment "Webcam devices" source "drivers/media/usb/uvc/Kconfig" source "drivers/media/usb/gspca/Kconfig" source "drivers/media/usb/pwc/Kconfig" source "drivers/media/usb/cpia2/Kconfig" source "drivers/media/usb/zr364xx/Kconfig" source "drivers/media/usb/stkwebcam/Kconfig" source "drivers/media/usb/s2255/Kconfig" source "drivers/media/usb/usbtv/Kconfig" endif If we'll be adding it, I would expect a corresponding change at drivers/media/platform/Kconfig. Thanks, Mauro
