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/Makefile

Mon, 07 Nov 2022 14:18:13 +0000

media: atmel: move microchip_csi2dc to dedicated microchip platformThe Atmel ISC will be moved to staging thus the atmel platform will onlyhave the ISI driver.The new media-controller converted ISC driver will be placed inside adedicated microchip platform directory.It is then natural to have the microchip-csi2dc moved to this new platformdirectory.The next step is to add the Microchip ISC driver to the new platformdirectory and reside together with the Microchip CSI2DC 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/Makefile

media: atmel: fix build when ISC=m and XISC=yBuilding 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 betweenthe two drivers.The solution is to create another Kconfig symbol that is automaticallyselected and generates the module atmel-isc-base.ko. This module can beloaded when both drivers are modules, or built-in when at least one of themis built-in.Reported-by: kernel test robot Fixes: c9aa973884a1 ("media: atmel: atmel-isc: add microchip-xisc 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/Makefile
