Supporting\npatches add support for the bayer-agnostic pixel formats that are\noutput by the rzg2l-cru driver, which is the devices used to capture\nimages on the kakip. A new class is added to the pipeline handler\nto interact with the CRU's V4L2 and Media Controller interfaces.\nThis should be seen as a short term solution - the CRU is not\nguaranteed to be the device filling this role for the C55 and so the\nideal would be modular pipelines.\n\nThe series is based on the recent set allowing matching of entity names\nusing regex patterns, as the rzg2l-cru driver registers its entities\nwith names incorporating memory addresses\n\nThanks\nDan\n\n[1] https://patchwork.libcamera.org/project/libcamera/list/?series=5293\n\nDaniel Scally (10):\n include: linux: Add Renesas RZ/G2L CRU Pixel Formats\n include: linux: Add RAWnn to drm_fourcc.h\n libcamera: bayer_format: Add \"NONE\" to BayerFormat::Order enum\n libcamera: bayer_format: Add CRU packing to BayerFormat\n libcamera: formats: Add CRU-packed RAWnn libcamera formats\n libcamera: bayer_format: Add entries for the CRU packed RAWnn formats\n libcamera: mali-c55: Add RZG2LCRU class\n libcamera: mali-c55: Move entity parameter from constructor to\n ::init()\n libcamera: mali-c55: Use the RZG2LCRU class\n libcamera: mali-c55: Match for memory input media entities\n\n .clang-format | 1 -\n include/libcamera/internal/bayer_format.h | 4 +-\n include/linux/drm_fourcc.h | 9 +\n include/linux/videodev2.h | 6 +\n src/libcamera/bayer_format.cpp | 13 +\n src/libcamera/formats.cpp | 30 ++\n src/libcamera/formats.yaml | 13 +\n src/libcamera/pipeline/mali-c55/mali-c55.cpp | 326 ++++++++++++++++--\n src/libcamera/pipeline/mali-c55/meson.build | 3 +-\n src/libcamera/pipeline/mali-c55/rzg2l-cru.cpp | 236 +++++++++++++\n src/libcamera/pipeline/mali-c55/rzg2l-cru.h | 66 ++++\n src/libcamera/sensor/camera_sensor_legacy.cpp | 6 +\n 12 files changed, 680 insertions(+), 33 deletions(-)\n create mode 100644 src/libcamera/pipeline/mali-c55/rzg2l-cru.cpp\n create mode 100644 src/libcamera/pipeline/mali-c55/rzg2l-cru.h"}
