Tue, 15 Mar 2022 06:04:01 +0000

media: spi: Kconfig: Place SPI drivers on a single menuIt makes no sense to have two menus for SPI drivers, eachone with a single driver. Merge them and keep the Kconfigsorted.Suggested-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/spi/Kconfig

9958d30f - media: Kconfig: cleanup VIDEO_DEV dependencies

Sun, 13 Mar 2022 06:25:46 +0000

media: Kconfig: cleanup VIDEO_DEV dependenciesmedia 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 thatimplement the newer API and drivers that implemented the former one.With time, such meaning changed, specially after the removal ofall V4L version 1 drivers.At the current implementation, VIDEO_DEV only does (1): it enablesthe media options related to V4L, that now has: menu "Video4Linux options" visible if VIDEO_DEV source "drivers/media/v4l2-core/Kconfig" endmenubut it doesn't affect anymore the V4L core drivers.The rationale is that the V4L2 core has a "soft" dependencyat the I2C bus, and now requires to select a number of otherKconfig 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_DEVIn the past, merging them would be tricky, but it seems that it is nowpossible to merge those symbols, in order to simplify V4L dependencies.Let's keep VIDEO_DEV, as this one is used on some make *defconfigconfigurations.Suggested-by: Laurent Pinchart Reviewed-by: Laurent Pinchart Reviewed-by: Jacopo Mondi Reviewed-by: Neil Armstrong # for meson-vdec & meson-ge2dAcked-by: Andrzej Pietrasiewicz Acked-by: Łukasz Stelmach Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/spi/Kconfig

5c57ae64 - media: i2c/Kconfig: use sub-menus for I2C support

Wed, 15 Apr 2020 13:39:38 +0000

media: i2c/Kconfig: use sub-menus for I2C supportThere are *lots* of I2C ancillary drivers. While we're usingcomments to group them, all options appear at the same menu.It should be a lot clearer to group them into sub-menus, withmay help people to go directly to the driver(s) he's needingto enable.Suggested-by: Hans Verkuil Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/spi/Kconfig

32a363d0 - media: Kconfig files: use select for V4L2 subdevs and MC

Wed, 25 Mar 2020 14:36:56 +0000

media: Kconfig files: use select for V4L2 subdevs and MCThere are lots of drivers that only work when the media controllerand/or the V4L2 subdev APIs are present.Right now, someone need to first enable those APIs beforeusing those drivers.Well, ideally, drivers, should, instead *optionally*depend on it, in order for PC camera drivers to be able to usethem, but nowadays most drivers are UVC cameras, with don'trequire a sensor driver.So, be it.Let's instead make them select the MEDIA_CONTROLLER and theSUBDEV API, in order to make easier for people to be ableof enabling them.Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/spi/Kconfig

4fa4ef39 - media: Clarify how menus are hidden by SUBDRV_AUTOSELECT

Sat, 27 Jul 2019 13:31:29 +0000

media: Clarify how menus are hidden by SUBDRV_AUTOSELECTSome users have been having a hard time finding the hiddenmenus. A typically case are camera sensor drivers(e.g IMX219, OV5645, etc), which are common on embeddedplatforms and not really "ancillary" devices.The problem with MEDIA_SUBDRV_AUTOSELECT seems to be relatedto the fact that it uses the "visible" syntax to hidethe menus.This is not obvious and it normally takes some time tofigure out.To fix the problem, add a comment on each of hidden menus,which should clarify what option is causing menus to be hidden.Signed-off-by: Ezequiel Garcia Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/spi/Kconfig

8169cf0a - media: Kconfig: allow to select drivers if EMBEDDED

Fri, 11 Jan 2019 15:49:51 +0000

media: Kconfig: allow to select drivers if EMBEDDEDEmbedded systems often connect to sensors or other multimediasubdevices directly. Currently, to be able to select such asubdevice (e.g. CONFIG_VIDEO_OV5640) disabling of the auto-select config option is needed (CONFIG_MEDIA_SUBDRV_AUTOSELECT).This is inconvenient as the ancillary drivers for a particulardevice then need to be selected manually.Allow to select drivers manually while keeping the auto-selectfeature in case EXPERT (selected by EMBEDDED) is enabled.Signed-off-by: Stefan Agner Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/spi/Kconfig
