    media: Kconfig: better support hybrid TV devices · a3b91d8b
    Mauro Carvalho Chehab authored
    Right now, if one has an hybrid TV card, it has to select
    both analog and digital TV support, as otherwise the needed
    core support won't be selected.
    
    Change the logic to auto-select the core support for those
    drivers, as this is a way more intuitive.
    
    It should be noticed that, as now both DVB_CORE and VIDEO_DEV
    defaults depends on selecting a hybrid cards, we had to remove
    the explicit dependencies there, in order to avoid circular
    dependencies.
    
    That requires some tricks:
    
    1) the prompt should not be not visible when an hybrid card
       is selected, as the user shold not change it.
    
    2) When a media hybrid device is selected, the modular
       option for DVB_CORE and VIDEO_DEV will follow the
       MEDIA_SUPPORT dependency, as we can't have a core
       built with "y" with a driver built as module.
    
    Note: while here, moved two pure V4L2 PCI drivers out of the
    "hybrid" part of config and consider pvrusb2 as an hybrid
    device.

	  This is a video4linux driver for Conexant 23416 based
	  usb2 personal video recorder devices.

	  To compile this driver as a module, choose M here: the
	  module will be called pvrusb2

config VIDEO_PVRUSB2_SYSFS
	bool "pvrusb2 sysfs support"
	default y
	depends on VIDEO_PVRUSB2 && SYSFS
	help
	  This option enables the operation of a sysfs based
	  interface for query and control of the pvrusb2 driver.

	  This is not generally needed for v4l applications,
	  although certain applications are optimized to take
	  advantage of this feature.

	  If you are in doubt, say Y.

	  Note: This feature is experimental and subject to change.

config VIDEO_PVRUSB2_DVB
	bool "pvrusb2 ATSC/DVB support"
	default y

	help
	  This option enables a DVB interface for the pvrusb2 driver.
	  If your device does not support digital television, this
	  feature will have no affect on the driver's operation.

	  If you are in doubt, say Y.

config VIDEO_PVRUSB2_DEBUGIFC
	bool "pvrusb2 debug interface"
	depends on VIDEO_PVRUSB2_SYSFS
	help
	  This option enables the inclusion of a debug interface
	  in the pvrusb2 driver, hosted through sysfs.

	  You do not need to select this option unless you plan
	  on debugging the driver or performing a manual firmware
	  extraction.

	  If you are in doubt, say N.
