It allows using a CSI-2 sensor with a PARALLEL interface. Current driver implementation doesn't support CSI-2 second input port usage. It doesn't support also YUV420, RGB565 and RGB444 input formats. Thanks to Sakari for review. Changes in v5: - Typo - Remove useless MEDIA_CONTROLLER from Kconfig - Replace v4l2_fwnode_endpoint_alloc_parse usage by v4l2_fwnode_endpoint_parse since not more variable size data usage - Add missing mutex_destroy calls - Switch to probe_new since I²C ID table is not used - Add new patch to add MEDIA_BUS_FMT_BGR888_3X8 needed output format - Add MEDIA_BUS_FMT_BGR888_3X8 usage in serial_to_parallel_code Changes in v4: - Fix and clarify endpoints properties documentation - Add support of enum_mbus_code - Only use V4L2_CID_PIXEL_RATE to compute link speed - Use MEDIA_BUS_FMT_UYVY8_1X16 instead of MEDIA_BUS_FMT_UYVY8_2X8 for CSI-2 link - Fix miscellaneous typos - Fix wrong code behavior for set_fmt and get_fmt Changes in v3: - Fix potential wrong error code for mipid02_stream_disable and mipid02_stream_enable - Remove useless memset for ep in mipid02_parse_rx_ep and mipid02_parse_tx_ep - Add second CSI-2 input pad even if it's not yet supported - Add support of get_fmt, set_fmt and link_validate and only access subdev connected to mipid02 Changes in v2: - Add precision about first CSI-2 port data rate - Document endpoints supported properties - Rename 'mipid02@14' into generic 'csi2rx@14' in example - Merge MAINTAINERS patch 3 into patch 1 and 2 - Fix line too long in Kconfig - Add missing delay after reset release - Various style fixes - Fix mipid02_stream_enable returning no error when mipid02_find_sensor failed Mickael Guene (3): media: uapi: Add MEDIA_BUS_FMT_BGR888_3X8 media bus format dt-bindings: Document MIPID02 bindings media: st-mipid02: MIPID02 CSI-2 to PARALLEL bridge driver .../bindings/media/i2c/st,st-mipid02.txt | 82 ++ Documentation/media/uapi/v4l/subdev-formats.rst | 107 ++ MAINTAINERS | 8 + drivers/media/i2c/Kconfig | 13 + drivers/media/i2c/Makefile | 1 + drivers/media/i2c/st-mipid02.c | 1033 ++++++++++++++++++++ include/uapi/linux/media-bus-format.h | 3 +- 7 files changed, 1246 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/media/i2c/st,st-mipid02.txt create mode 100644 drivers/media/i2c/st-mipid02.c -- 2.7.4
