That was actually my first option ;-) VIDEO_V4L2 (or VIDEO_V4L) is a much better name. From my side, I'm fine either way. As a plus, using VIDEO_V4L2 would produce a much smaller patch that won't be rejected by some ML servers, but maybe it would require distros and people who have their own .config files stored somewhere to re-configure their Kernels. > [snip] > > > diff --git a/drivers/media/pci/tw5864/Kconfig b/drivers/media/pci/tw5864/Kconfig > > index d376d4ed65b9..0a0f3191f238 100644 > > --- a/drivers/media/pci/tw5864/Kconfig > > +++ b/drivers/media/pci/tw5864/Kconfig > > @@ -1,7 +1,7 @@ > > # SPDX-License-Identifier: GPL-2.0-only > > config VIDEO_TW5864 > > tristate "Techwell TW5864 video/audio grabber and encoder" > > - depends on VIDEO_DEV && PCI && VIDEO_V4L2 > > + depends on VIDEO_DEV && PCI && VIDEO_DEV > > You can drop the second VIDEO_DEV. > > > select VIDEOBUF2_DMA_CONTIG > > help > > Support for boards based on Techwell TW5864 chip which provides > > diff --git a/drivers/media/pci/tw68/Kconfig b/drivers/media/pci/tw68/Kconfig > > index af0cb60337bb..ef29be7db493 100644 > > --- a/drivers/media/pci/tw68/Kconfig > > +++ b/drivers/media/pci/tw68/Kconfig > > @@ -1,7 +1,7 @@ > > # SPDX-License-Identifier: GPL-2.0-only > > config VIDEO_TW68 > > tristate "Techwell tw68x Video For Linux" > > - depends on VIDEO_DEV && PCI && VIDEO_V4L2 > > + depends on VIDEO_DEV && PCI && VIDEO_DEV > > Here too. > > Apart from that, the patch looks good to me. > > Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Thanks!

Yes. See, I2C is a tristate, so, the above evaluates to: if I2C=n => no dependency at I2C If I2C is either "M" or "Y" config VIDEO_DEV depends on I2C. That's the way to tell the build system that, if I2C is compiled as "M", VIDEO_DEV can't be compiled as "Y". > > > + select RATIONAL > > + select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE > > help > > Enables the V4L2 API, used by cameras, analog TV, video grabbers, > > radio devices and by some input devices. > > diff --git a/drivers/media/common/saa7146/Kconfig b/drivers/media/common/saa7146/Kconfig > > index 3e85c0c3fd9a..a0aa155e5d85 100644 > > --- a/drivers/media/common/saa7146/Kconfig > > +++ b/drivers/media/common/saa7146/Kconfig > > @@ -5,6 +5,6 @@ config VIDEO_SAA7146 > > > > config VIDEO_SAA7146_VV > > tristate > > - depends on VIDEO_V4L2 > > + depends on VIDEO_DEV > > select VIDEOBUF_DMA_SG > > select VIDEO_SAA7146 > > diff --git a/drivers/media/dvb-core/Kconfig b/drivers/media/dvb-core/Kconfig > > index 6ffac618417b..8b3f2d53cd62 100644 > > --- a/drivers/media/dvb-core/Kconfig > > +++ b/drivers/media/dvb-core/Kconfig > > @@ -6,7 +6,7 @@ > > config DVB_MMAP > > bool "Enable DVB memory-mapped API (EXPERIMENTAL)" > > depends on DVB_CORE > > - depends on VIDEO_V4L2=y || VIDEO_V4L2=DVB_CORE > > + depends on VIDEO_DEV=y || VIDEO_DEV=DVB_CORE > > select VIDEOBUF2_VMALLOC > > help > > This option enables DVB experimental memory-mapped API, which > > diff --git a/drivers/media/dvb-frontends/Kconfig b/drivers/media/dvb-frontends/Kconfig > > index 2c1ed98d43c5..4101f9b1e731 100644 > > --- a/drivers/media/dvb-frontends/Kconfig > > +++ b/drivers/media/dvb-frontends/Kconfig > > @@ -510,7 +510,7 @@ config DVB_RTL2832 > > > > config DVB_RTL2832_SDR > > tristate "Realtek RTL2832 SDR" > > - depends on DVB_CORE && I2C && I2C_MUX && VIDEO_V4L2 && MEDIA_SDR_SUPPORT && USB > > + depends on DVB_CORE && I2C && I2C_MUX && VIDEO_DEV && MEDIA_SDR_SUPPORT && USB > > select DVB_RTL2832 > > select VIDEOBUF2_VMALLOC > > default m if !MEDIA_SUBDRV_AUTOSELECT > > @@ -681,7 +681,7 @@ config DVB_AU8522_DTV > > > > config DVB_AU8522_V4L > > tristate "Auvitek AU8522 based ATV demod" > > - depends on VIDEO_V4L2 && DVB_CORE && I2C > > + depends on VIDEO_DEV && DVB_CORE && I2C > > select DVB_AU8522 > > default m if !MEDIA_SUBDRV_AUTOSELECT > > help > > diff --git a/drivers/media/i2c/Kconfig b/drivers/media/i2c/Kconfig > > index e7194c1be4d2..5abc169f0a5c 100644 > > --- a/drivers/media/i2c/Kconfig > > +++ b/drivers/media/i2c/Kconfig > > @@ -3,7 +3,7 @@ > > # Multimedia Video device configuration > > # > > > > -if VIDEO_V4L2 > > +if VIDEO_DEV > > > > comment "IR I2C driver auto-selected by 'Autoselect ancillary drivers'" > > depends on MEDIA_SUBDRV_AUTOSELECT && I2C && RC_CORE > > @@ -36,7 +36,7 @@ menu "Audio decoders, processors and mixers" > > > > config VIDEO_TVAUDIO > > tristate "Simple audio decoder chips" > > - depends on VIDEO_V4L2 && I2C > > + depends on VIDEO_DEV && I2C > > Are there symbols in drivers/media/i2c that do not depend on I2C ? > Could we make the menu conditional on I2C presence ?
