As discussed on the ML, moving forward with having the media link validate at start/stop streaming call. I will test the patch : [RFC PATCHv2] vb2: add support for (un)prepare_streaming queue ops afterwards, but that patch requires moving my logic to the new vb2 callbacks. 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 (5): media: atmel: atmel-isc: prepare for media controller support media: atmel: atmel-isc: implement media controller ARM: dts: at91: sama7g5: add nodes for video capture ARM: configs: at91: sama7: add xisc and csi2dc ARM: multi_v7_defconfig: add atmel video pipeline modules arch/arm/boot/dts/sama7g5.dtsi | 51 ++ arch/arm/configs/multi_v7_defconfig | 3 + arch/arm/configs/sama7_defconfig | 2 + drivers/media/platform/atmel/Makefile | 2 +- drivers/media/platform/atmel/atmel-isc-base.c | 485 +++++++++--------- .../media/platform/atmel/atmel-isc-scaler.c | 267 ++++++++++ drivers/media/platform/atmel/atmel-isc.h | 50 +- .../media/platform/atmel/atmel-sama5d2-isc.c | 34 +- .../media/platform/atmel/atmel-sama7g5-isc.c | 32 +- 9 files changed, 685 insertions(+), 241 deletions(-) create mode 100644 drivers/media/platform/atmel/atmel-isc-scaler.c
