2021-07-30media: atmel: fix build when ISC=m and XISC=yEugen Hristev
Building VIDEO_ATMEL_ISC as module and VIDEO_ATMEL_XISC as built-in (or viceversa) causes build errors: or1k-linux-ld: drivers/media/platform/atmel/atmel-isc-base.o: in function `isc_async_complete': atmel-isc-base.c:(.text+0x40d0): undefined reference to `__this_module' or1k-linux-ld: atmel-isc-base.c:(.text+0x40f0): undefined reference to `__this_module' or1k-linux-ld: drivers/media/platform/atmel/atmel-isc-base.o:(.rodata+0x390): undefined reference to `__this_module' or1k-linux-ld: drivers/media/platform/atmel/atmel-isc-base.o:(__param+0x4): undefined reference to `__this_module' or1k-linux-ld: drivers/media/platform/atmel/atmel-isc-base.o:(__param+0x18): undefined reference to `__this_module' This is caused by the file atmel-isc-base.c which is common code between the two drivers. The solution is to create another Kconfig symbol that is automatically selected and generates the module atmel-isc-base.ko. This module can be loaded when both drivers are modules, or built-in when at least one of them is built-in.

2020-04-14media: Kconfig files: use select for V4L2 subdevs and MCMauro Carvalho Chehab
There are lots of drivers that only work when the media controller and/or the V4L2 subdev APIs are present. Right now, someone need to first enable those APIs before using those drivers. Well, ideally, drivers, should, instead *optionally* depend on it, in order for PC camera drivers to be able to use them, but nowadays most drivers are UVC cameras, with don't require a sensor driver. So, be it. Let's instead make them select the MEDIA_CONTROLLER and the SUBDEV API, in order to make easier for people to be able of enabling them.

Checkpatch wants to use 'help' instead of '---help---': WARNING: prefer 'help' over '---help---' for new help texts Let's change it globally at the media subsystem, as otherwise people would keep using the old way. Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
2018-05-28media: Remove depends on HAS_DMA in case of platform dependencyGeert Uytterhoeven
Remove dependencies on HAS_DMA where a Kconfig symbol depends on another symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST". In most cases this other symbol is an architecture or platform specific symbol, or PCI. Generic symbols and drivers without platform dependencies keep their dependencies on HAS_DMA, to prevent compiling subsystems or drivers that cannot work anyway. This simplifies the dependencies, and allows to improve compile-testing. Note: - The various VIDEOBUF*DMA* symbols had to loose their dependencies on HAS_DMA, as they are selected by several individual drivers.

Switch users of the v4l2_of_ APIs to the more generic v4l2_fwnode_ APIs. Async OF matching is replaced by fwnode matching and OF matching support is removed.
