This series is a continuation of the series that converts the atmel-isc driver to media controller paradigm: https://lore.kernel.org/lkml/20220503095127.48710-1-eugen.hristev@xxxxxxxxxxxxx/T/#mccad96a3122f2817bf1ae1db7eddf1a8cecb2749 As discussed on ML, the current Atmel ISC driver is moved to staging to keep the existing users happy, and readded to platform/microchip under a different Kconfig symbol and with the new media controller support which was reviewed in v10. I kept the original v10 patches on top of the movement of the driver to make it more clear what the conversion to media controller brings. Please let me know if this is okay or acceptable to take as it is, and if it complies with the requirements for the subsystem/ABI breakage, etc. Thanks to everyone for reviewing and helping in the discussions ! PLEASE NOTE: the series depends on the patch: vb2: add support for (un)prepare_streaming queue ops by Hans Verkuil I have a different patch as the last in the series that uses the new callbacks (and only that patch is dependant on the vb2: add support for (un)prepare_streaming queue ops ) Eugen Changes in v12: - moved patch 'move to staging' as last patch in the series - renamed exported symbols by Microchip ISC by adding prefix microchip_ - added TODO in staging dir - make old ISC kconfigs dependant to !VIDEO_MICROCHIP_ISC_BASE - move to staging deprecated dir Changes in v11: - moved atmel isc to staging - created platform/microchip to host the new MICROCHIP_ISC driver - it was natural to move the MICROCHIP_CSI2DC here - on top, add the patches that move to media controller Full series history: Changes in v10: -> split the series into this first fixes part. -> moved IO_MC addition from first patch to the second patch on the driver changes -> edited commit messages -> DT nodes now disabled by default. Changes in v9: -> kernel robot reported isc_link_validate is not static, changed to static. Changes in v8: -> scaler: modified crop bounds to have the exact source size Changes in v7: -> scaler: modified crop bounds to have maximum isc size -> format propagation: did small changes as per Jacopo review Changes in v6: -> worked a bit on scaler, added try crop and other changes as per Jacopo review -> worked on isc-base enum_fmt , reworked as per Jacopo review Changes in v5: -> removed patch that removed the 'stop' variable as it was still required -> added two new trivial patches -> reworked some parts of the scaler and format propagation after discussions with Jacopo Changes in v4: -> as reviewed by Hans, added new patch to remove the 'stop' variable and reworked one patch that was using it -> as reviewed by Jacopo, reworked some parts of the media controller implementation Changes in v3: - change in bindings, small fixes in csi2dc driver and conversion to mc for the isc-base. - removed some MAINTAINERS patches and used patterns in MAINTAINERS Changes in v2: - integrated many changes suggested by Jacopo in the review of the v1 series. - add a few new patches Eugen Hristev (6): media: atmel: move microchip_csi2dc to dedicated microchip platform media: microchip: add ISC driver as Microchip ISC media: microchip: microchip-isc: prepare for media controller support media: microchip: microchip-isc: implement media controller media: microchip: microchip-isc: move media_pipeline_* to (un)prepare cb media: atmel: atmel-isc: move to staging MAINTAINERS | 8 +- drivers/media/platform/Kconfig | 1 + drivers/media/platform/Makefile | 1 + drivers/media/platform/atmel/Kconfig | 51 - drivers/media/platform/atmel/Makefile | 7 - drivers/media/platform/microchip/Kconfig | 61 + drivers/media/platform/microchip/Makefile | 9 + .../{atmel => microchip}/microchip-csi2dc.c | 0 .../platform/microchip/microchip-isc-base.c | 2040 +++++++++++++++++ .../platform/microchip/microchip-isc-clk.c | 311 +++ .../platform/microchip/microchip-isc-regs.h | 413 ++++ .../platform/microchip/microchip-isc-scaler.c | 267 +++ .../media/platform/microchip/microchip-isc.h | 400 ++++ .../microchip/microchip-sama5d2-isc.c | 683 ++++++ .../microchip/microchip-sama7g5-isc.c | 646 ++++++ drivers/staging/media/Kconfig | 1 + drivers/staging/media/Makefile | 1 + .../staging/media/deprecated/atmel/Kconfig | 48 + .../staging/media/deprecated/atmel/Makefile | 8 + drivers/staging/media/deprecated/atmel/TODO | 34 + .../media/deprecated}/atmel/atmel-isc-base.c | 20 +- .../media/deprecated}/atmel/atmel-isc-clk.c | 8 +- .../media/deprecated}/atmel/atmel-isc-regs.h | 0 .../media/deprecated}/atmel/atmel-isc.h | 16 +- .../deprecated}/atmel/atmel-sama5d2-isc.c | 18 +- .../deprecated}/atmel/atmel-sama7g5-isc.c | 18 +- 26 files changed, 4969 insertions(+), 101 deletions(-) create mode 100644 drivers/media/platform/microchip/Kconfig create mode 100644 drivers/media/platform/microchip/Makefile rename drivers/media/platform/{atmel => microchip}/microchip-csi2dc.c (100%) create mode 100644 drivers/media/platform/microchip/microchip-isc-base.c create mode 100644 drivers/media/platform/microchip/microchip-isc-clk.c create mode 100644 drivers/media/platform/microchip/microchip-isc-regs.h create mode 100644 drivers/media/platform/microchip/microchip-isc-scaler.c create mode 100644 drivers/media/platform/microchip/microchip-isc.h create mode 100644 drivers/media/platform/microchip/microchip-sama5d2-isc.c create mode 100644 drivers/media/platform/microchip/microchip-sama7g5-isc.c create mode 100644 drivers/staging/media/deprecated/atmel/Kconfig create mode 100644 drivers/staging/media/deprecated/atmel/Makefile create mode 100644 drivers/staging/media/deprecated/atmel/TODO rename drivers/{media/platform => staging/media/deprecated}/atmel/atmel-isc-base.c (99%) rename drivers/{media/platform => staging/media/deprecated}/atmel/atmel-isc-clk.c (97%) rename drivers/{media/platform => staging/media/deprecated}/atmel/atmel-isc-regs.h (100%) rename drivers/{media/platform => staging/media/deprecated}/atmel/atmel-isc.h (96%) rename drivers/{media/platform => staging/media/deprecated}/atmel/atmel-sama5d2-isc.c (97%) rename drivers/{media/platform => staging/media/deprecated}/atmel/atmel-sama7g5-isc.c (97%) -- 2.25.1
