55927c98 - media: atmel: atmel-isc: move to staging

Mon, 07 Nov 2022 14:18:18 +0000

media: atmel: atmel-isc: move to stagingThe Atmel ISC driver is not compliant with media controller specification.In order to evolve this driver, it has to move to media controller, tosupport enhanced features and future products which embed it.The move to media controller involves several changes which arenot backwards compatible with the current usability of the driver.The best example is the way the format is propagated from the top videodriver /dev/videoX down to the sensor.In a simple configuration sensor ==> isc , the isc just calls subdev s_fmtand controls the sensor directly. This is achieved by having a lot of codeinside the driver that will query the subdev at probe time and make a listof formats which are usable.Basically the user has nothing to configure, as the isc will handleeverything at the top level. This is an easy way to capture, but also comeswith the drawback of lack of flexibility.In a more complicated pipelinesensor ==> controller 1 ==> controller 2 ==> iscthis will not be achievable, as controller 1 and controller 2 might bemedia-controller configurable, and will not propagate the formats down tothe sensor.After discussions with the media maintainers, the decision is to moveAtmel ISC to staging as-is, to keep the Kconfig symbols and the usersto the driver in staging. Thus, all the existing users of the nonmedia-controller paradigm will continue to be happy and use the old configway.The new driver was added in the media subsystem with a differentsymbol, with the conversion to media controller done, and new usersof the driver will be able to use all the new features.This patch is merely a file move to staging, not affecting any of theusers.The exported symbols had to be renamed to atmel_* to avoid duplication withthe new Microchip ISC driver.Signed-off-by: Eugen Hristev Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/platform/atmel/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/platform/atmel/Kconfig

Fri, 11 Mar 2022 10:21:45 +0000

media: platform: move platform menu dependencies to driversRight now, platform dependencies are organized by the type ofthe platform driver. Yet, things tend to become very messy withtime. The better seems to organize the drivers per manufacturer,as other Kernel subsystems are doing.As a preparation for such purpose, get rid of menuconfigs,moving the per-menu dependencies to be at the driver-specifigconfig entires.This shoud give flexibility to reorganize the platform driversper manufacturer and re-sort them.This patch removes all "if..endif" options from the platformKconfig, converting them into depends on.Acked-by: Jernej Skrabec Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/platform/atmel/Kconfig
