media: microchip: microchip-isc: implement media controllerAs a top MC video driver, the microchip-isc should not propagate the formatto the subdevice, it should rather check at start_streaming() time if thesubdev is properly configured with a compatible format.Removed the whole format finding logic, and reworked the formatverification at start_streaming time, such that the ISC will return anerror if the subdevice is not properly configured.To achieve this, media_pipeline_start is called and a link_validatecallback is created to check the formats.With this being done, the module parameter 'sensor_preferred' makes nosense anymore. The ISC should not decide which format the sensor is using.The ISC should only cope with the situation and inform userspace if thestreaming is possible in the current configuration.The redesign of the format propagation has also risen the question of theenumfmt callback. If enumfmt is called with an mbus_code, the enumfmthandler should only return the formats that are supported for thismbus_code. Otherwise, the enumfmt will report all the formats that the ISCcould output.With this rework, the dynamic list of user formats is removed. It makes nomore sense to identify at complete time which formats the sensor couldemit, and add those into a separate dynamic list.The ISC will start with a simple preconfigured default format, and atlink validate time, decide whether it can use the format that isconfigured on the sink or not.>From now on, the driver also advertises the IO_MC capability.Signed-off-by: Eugen Hristev Reviewed-by: Jacopo Mondi Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab List of files: /linux/drivers/media/platform/microchip/Kconfig

Mon, 07 Nov 2022 15:18:14 +0100

media: microchip: add ISC driver as Microchip ISCThe Atmel ISC driver will be moved to staging to support old users thatare not using the media controller paradigm.The ISC driver was converted to media controller in the public patchseries:https://lore.kernel.org/lkml/20220503095127.48710-1-eugen.hristev@microchip.com/T/#m2c320fa8153c01379a1c35b1d90a00903949513aHowever the conversion cannot be done directly as it would affect existingusers by breaking the old way of configuration for sama5d2 platforms.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 converted driver would support both sama5d2 and sama7g5 platforms withmedia controller paradigm, but it requires userspace configuration of thepipeline for all the pipeline modules.In a simple configuration sensor ==> isc , the old isc driver used to callsubdev s_fmt and control the sensor directly.This was achieved by having a lot of code inside the driver that wasquerying the subdev at probe time and made a list of formats which areusable.Basically the user had nothing to configure, as the isc would handleeverything at the top level. This was an easy way to capture, but also camewith the drawback of lack of flexibility.In a more complicated pipeline sensor ==> controller 1 ==> controller 2 ==> iscthis would not be achievable, as controller 1 and controller 2 might bemedia-controller configurable, and will not propagate the formats down tothe sensor.The new driver Microchip ISC would solve all these problems and exposes padsentities and links to userspace.For the ease of tracking, the patches that convert to media controller comeon top of this patch that simply readds the driver to the new location underthe new Kconfig symbols.To differentiate between the old driver and the new driver, I have renamedthe new driver to Microchip ISC, renaming the Kconfig symbols as well, andall the mentions inside the driver.The only thing that remains common is the fileinclude/linux/atmel-isc-media.h which is the ABI for the v4l2 customcontrols that the ISC exposes.This file is used by both driver, so I kept it as-is.To further avoid confusion all files have been renamed and all functionsnamed isc_* as well.The exported symbols have been renamed with added microchip_ prefix, toavoid symbol duplication with the old driver, and to avoid confusion.Other than that, I have fixed small checkpatch issues when readding thedriver.Signed-off-by: Eugen Hristev Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab List of files: /linux/drivers/media/platform/microchip/Kconfig
