media: Kconfig: cleanup VIDEO_DEV dependencies media Kconfig has two entries associated to V4L API: VIDEO_DEV and VIDEO_V4L2. On Kernel 2.6.x, there were two V4L APIs, each one with its own flag. VIDEO_DEV were meant to: 1) enable Video4Linux and make its Kconfig options to appear; 2) it makes the Kernel build the V4L core. while VIDEO_V4L2 where used to distinguish between drivers that implement the newer API and drivers that implemented the former one. With time, such meaning changed, specially after the removal of all V4L version 1 drivers. At the current implementation, VIDEO_DEV only does (1): it enables the media options related to V4L, that now has: menu "Video4Linux options" visible if VIDEO_DEV source "drivers/media/v4l2-core/Kconfig" endmenu but it doesn't affect anymore the V4L core drivers. The rationale is that the V4L2 core has a "soft" dependency at the I2C bus, and now requires to select a number of other Kconfig options: config VIDEO_V4L2 tristate depends on (I2C || I2C=n) && VIDEO_DEV select RATIONAL select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE default (I2C || I2C=n) && VIDEO_DEV In the past, merging them would be tricky, but it seems that it is now possible to merge those symbols, in order to simplify V4L dependencies. Let's keep VIDEO_DEV, as this one is used on some make *defconfig configurations.

Revert "media: Kconfig: better support hybrid TV devices" Changing from "depends on" to "select" may cause some side-effects. This patch is not ready to be merged yet, as it requires some adjustments. So, let's revert it. This reverts commit a3b91d8bd1e034c8ed89d3f55243478af97a0a52.

media: Kconfig: better support hybrid TV devices 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. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

media: fix media Kconfig help syntax issues The help text should be indented by at least two spaces after the 'help' separator. This is both good practice and the media_build system for building media drivers makes this assumption. I went through all Kconfigs under drivers/media and fixed any bad help sections. This makes it conform to the common practice and should fix problems with 'make menuconfig' when using media_build. This is due to a "WARNING" message that media_build can insert in the Kconfig and that assumes the help text is indented by at least two spaces. If not, then the Kconfig becomes invalid and 'make menuconfig' fails.

[media] Kconfig: merge all customise options into just one Instead of having 3 options to allow customizing the media sub-drivers (tuners, I2C drivers, frontends), merge all of them into just one. That simplifies the life for users, as they can just keep this untouched. Life for developers is also simpler, as there's now just one Kconfig item to remember, for the ancillary sub-drivers providing supports for chips that could change from one board design to another.
