The driver uses the media controller API and in this initial support implements both of the ISP's capture pipelines allowing a range of output formats plus downscaling and cropping. The capture pipelines are named "Full resolution" and "Downscale" and so abbreviated FR and DS throughout the driver. The driver exposes 4 V4L2 subdevices: - mali-c55 isp: input data formatting - mali-c55 tpg: test pattern generator (modeled as a camera sensor entity) - mali-c55 resizer fr: downscale / crop and format setting for the FR pipe - mali-c55 resizer ds: downscale / crop and format setting for the DS pipe Thanks Dan Daniel Scally (5): media: uapi: Add MEDIA_BUS_FMT_RGB202020_1X60 format code dt-bindings: media: Add bindings for ARM mali-c55 media: mali-c55: Add Mali-C55 ISP driver media: Documentation: Add Mali-C55 ISP Documentation MAINTAINERS: Add entry for mali-c55 driver .../admin-guide/media/mali-c55-graph.dot | 19 + Documentation/admin-guide/media/mali-c55.rst | 318 ++++++ .../admin-guide/media/v4l-drivers.rst | 1 + .../bindings/media/arm,mali-c55.yaml | 51 + .../media/v4l/subdev-formats.rst | 168 +++ MAINTAINERS | 10 + drivers/media/platform/Kconfig | 1 + drivers/media/platform/Makefile | 1 + drivers/media/platform/arm/Kconfig | 5 + drivers/media/platform/arm/Makefile | 2 + drivers/media/platform/arm/mali-c55/Kconfig | 18 + drivers/media/platform/arm/mali-c55/Makefile | 9 + .../platform/arm/mali-c55/mali-c55-capture.c | 1013 +++++++++++++++++ .../platform/arm/mali-c55/mali-c55-common.h | 263 +++++ .../platform/arm/mali-c55/mali-c55-core.c | 717 ++++++++++++ .../platform/arm/mali-c55/mali-c55-isp.c | 682 +++++++++++ .../arm/mali-c55/mali-c55-registers.h | 180 +++ .../arm/mali-c55/mali-c55-resizer-coefs.h | 382 +++++++ .../platform/arm/mali-c55/mali-c55-resizer.c | 678 +++++++++++ .../platform/arm/mali-c55/mali-c55-tpg.c | 425 +++++++ include/uapi/linux/media-bus-format.h | 3 +- 21 files changed, 4945 insertions(+), 1 deletion(-) create mode 100644 Documentation/admin-guide/media/mali-c55-graph.dot create mode 100644 Documentation/admin-guide/media/mali-c55.rst create mode 100644 Documentation/devicetree/bindings/media/arm,mali-c55.yaml create mode 100644 drivers/media/platform/arm/Kconfig create mode 100644 drivers/media/platform/arm/Makefile create mode 100644 drivers/media/platform/arm/mali-c55/Kconfig create mode 100644 drivers/media/platform/arm/mali-c55/Makefile create mode 100644 drivers/media/platform/arm/mali-c55/mali-c55-capture.c create mode 100644 drivers/media/platform/arm/mali-c55/mali-c55-common.h create mode 100644 drivers/media/platform/arm/mali-c55/mali-c55-core.c create mode 100644 drivers/media/platform/arm/mali-c55/mali-c55-isp.c create mode 100644 drivers/media/platform/arm/mali-c55/mali-c55-registers.h create mode 100644 drivers/media/platform/arm/mali-c55/mali-c55-resizer-coefs.h create mode 100644 drivers/media/platform/arm/mali-c55/mali-c55-resizer.c create mode 100644 drivers/media/platform/arm/mali-c55/mali-c55-tpg.c
