There is still room for refactoring and\nsimplification of the imx7-media-csi driver, but I believe it is now in\na state clean enough to be moved out of staging.\n\nThe series also includes a few fixes or improvements in supported\nformats that are now made possible thanks to this refactoring. See\npatches 45/50 and 46/50 for details.\n\nThe code size has grown as a result. This is partly offset by code in\nthe shared helpers that can be removed or simplified, but I haven't\nstarting working on that. The helpers are now used for the i.MX6 IPUv3\nonly, so I will leave this exercise to anyone who would be interested in\ndestaging that driver as well.\n\nSome of the items in the TODO file related to the imx7-media-csi driver\nhave been addressed. The two remaining items are frame interval monitor\nsupport and restricting the list of supported formats to the SoC\nversion. The former isn't a destaging blocker in my opinion, as the\nfeature can be added later if desired (and frame interval monitoring\nshould then be moved to the V4L2 core). I believe the latter could also\nbe addressed after destaging the driver, but in any case, this is a\ndiscussion for a future destaging series (which may come as soon as this\none is accepted).\n\nAlexander, this also could greatly simplify your \"[PATCH v3 0/8]\nimx7/imx8mm media / csi patches\" series.\n\nLaurent Pinchart (48):\n staging: media: imx: imx7-media-csi: Initialize locks early on\n staging: media: imx: imx7-media-csi: Split imx_media_dev from probe()\n staging: media: imx: imx7-media-csi: Import notifier helpers\n staging: media: imx: imx7-media-csi: Drop duplicate link creation\n staging: media: imx: imx7-media-csi: Drop the imx_media notifier\n staging: media: imx: imx7-media-csi: Don't populate vdev lists\n staging: media: imx: imx7-media-csi: Drop unused frame_interval\n staging: media: imx: imx7-media-csi: Move format init to probe time\n staging: media: imx: imx7-media-csi: Import video device helpers\n staging: media: imx: imx7-media-csi: Drop legacy video device support\n staging: media: imx: imx7-media-csi: Drop unused controls support\n staging: media: imx: imx7-media-csi: Reorganize imx7_csi structure\n staging: media: imx: imx7-media-csi: Fold capture_priv into imx7_csi\n staging: media: imx: imx7-media-csi: Ensure consistent function prefix\n staging: media: imx: imx7-media-csi: Don't set subdev group id\n staging: media: imx: imx7-media-csi: Import imx_media_dev_init()\n helper\n staging: media: imx: imx7-media-csi: Embed imx_media_dev in imx7_csi\n staging: media: imx: imx7-media-csi: Drop imx_media_add_video_device\n call\n staging: media: imx: imx7-media-csi: Don't initialize unused fields\n staging: media: imx: imx7-media-csi: Inline imx_media_pipeline_pad()\n staging: media: imx: imx7-media-csi: Import\n imx_media_pipeline_set_stream()\n staging: media: imx: imx7-media-csi: Avoid unnecessary casts\n staging: media: imx: imx7-media-csi: Inline pipeline start/stop\n staging: media: imx: imx7-media-csi: Fold imx_media_dev into imx7_csi\n staging: media: imx: imx7-media-csi: Decouple from imx_media_buffer\n staging: media: imx: imx7-media-csi: Fold imx_media_video_dev into\n imx7_csi\n staging: media: imx: imx7-media-csi: Store imx7_csi in drv data\n staging: media: imx: imx7-media-csi: Decouple from imx_media_dma_buf\n staging: media: imx: imx7-media-csi: Decouple from shared macros\n staging: media: imx: imx7-media-csi: Drop error message on alloc\n failure\n staging: media: imx: imx7-media-csi: Import format helpers\n staging: media: imx: imx7-media-csi: Replace ipu_color_space with bool\n yuv field\n staging: media: imx: imx7-media-csi: Drop IC support from\n imx7_csi_try_colorimetry()\n staging: media: imx: imx7-media-csi: Drop IPU-only formats\n staging: media: imx: imx7-media-csi: Drop unsupported YUV and RGB\n formats\n staging: media: imx: imx7-media-csi: Make default formats consistent\n staging: media: imx: imx7-media-csi: Define macro for default mbus\n code\n staging: media: imx: imx7-media-csi: Simplify default mbus code in\n try_fmt\n staging: media: imx: imx7-media-csi: Drop YUV/RGB/BAYER format\n selectors\n staging: media: imx: imx7-media-csi: Drop unneeded imx7_csi_pixfmt\n fields\n staging: media: imx: imx7-media-csi: Inline imx7_csi_init_mbus_fmt()\n staging: media: imx: imx7-media-csi: Simplify default format in\n try_fmt\n staging: media: imx: imx7-media-csi: Fix list of supported formats\n staging: media: imx: imx7-media-csi: Add V4L2_PIX_FMT_Y14 support\n staging: media: imx: imx7-media-csi: Drop unneeded pixel format\n validation\n staging: media: imx: imx7-media-csi: Inline\n imx7_csi_enum_pixel_formats()\n staging: media: imx: imx7-media-csi: Drop V4L2 events support\n staging: media: imx: imx7-media-csi: Drop usage of shared helpers\n\nPaul Elder (2):\n staging: media: imx: imx7-media-csi: Move misc init out of probe()\n staging: media: imx: imx7-media-csi: Remove imx_media_of_add_csi\n\n drivers/staging/media/imx/imx7-media-csi.c | 1370 +++++++++++++++++---\n 1 file changed, 1172 insertions(+), 198 deletions(-)\n\n\nbase-commit: c5eb0a61238dd6faf37f58c9ce61c9980aaffd7a" }
