include: linux: Add PiSP specific image and config buffer formats
Add the Raspberry Pi 5 PiSP specific compressed Bayer format types 1/2: - V4L2_PIX_FMT_PISP_COMP1_xxx - V4L2_PIX_FMT_PISP_COMP2_xxx Add the Raspberry Pi 5 PiSP Frontend and Backend config formats: - V4L2_META_FMT_RPI_FE_CFG - V4L2_META_FMT_RPI_BE_CFG Add the Raspberry Pi 5 PiSP Frontend statistics format: - V4L2_META_FMT_RPI_FE_STATS The corresponding changes submitted to the linux-media mailing list can be found at: (series "media: raspberrypi: Add support for PiSP Back End") https://lore.kernel.org/linux-media/20240502110503.38412-4-jacopo.mondi@ideasonboard.com/ https://lore.kernel.org/linux-media/20240502110503.38412-5-jacopo.mondi@ideasonboard.com/ and for the DRM mailing at: (patch "[RFC] drm/fourcc: Add RPI modifiers") https://lore.kernel.org/dri-devel/20240226153854.99471-1-jacopo.mondi@ideasonboard.com/ Signed-off-by: Naushir Patuck <naush@raspberrypi.com> Reviewed-by: David Plowman <david.plowman@raspberrypi.com> Reviewed-by: Jacopo Mondi <jacopo.mondi@ideasonboard.com> Signed-off-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
