This series is the v9 series that attempts to support media controller in the atmel ISC and XISC drivers. The CSI2DC driver was accepted thus removed from the patch series, together with other patches. Important note: this series applies on top of current media_staging tree, as it relies on previous patches in the series which were accepted. Thanks to everyone who reviewed my work ! Eugen 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 (13): media: atmel: atmel-isc-base: use streaming status when queueing buffers media: atmel: atmel-isc-base: replace is_streaming call in s_fmt_vid_cap media: atmel: atmel-isc: remove redundant comments media: atmel: atmel-isc: implement media controller media: atmel: atmel-sama5d2-isc: fix wrong mask in YUYV format check media: atmel: atmel-isc-base: use mutex to lock awb workqueue from streaming media: atmel: atmel-isc: compact the controller formats list media: atmel: atmel-isc: change format propagation to subdev into only verification media: atmel: atmel-sama7g5-isc: remove stray line dt-bindings: media: microchip,xisc: add bus-width of 14 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 .../bindings/media/microchip,xisc.yaml | 2 +- arch/arm/boot/dts/sama7g5.dtsi | 49 ++ 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 | 518 ++++++++++-------- .../media/platform/atmel/atmel-isc-scaler.c | 267 +++++++++ drivers/media/platform/atmel/atmel-isc.h | 58 +- .../media/platform/atmel/atmel-sama5d2-isc.c | 87 +-- .../media/platform/atmel/atmel-sama7g5-isc.c | 93 ++-- 10 files changed, 754 insertions(+), 327 deletions(-) create mode 100644 drivers/media/platform/atmel/atmel-isc-scaler.c -- 2.25.1
