The CSI-2 receiver (CRU) saves\nimages to memory and the ISP is fed through a dedicated DMA engine that\nprovides memory interfacing capabilities.\n\nThe series starts by adding support for the RZG2LCRU class (named after\nthe media device name) and then plumbs memory-to-memory operations in\nthe pipeline handler.\n\nWarning: The series depends on:\n[PATCH 0/6] include: linux: Update headers to Linux v6.18\n\nThe last patch on the series, is of course not for inclusion and is only\nthere to please the CI.\n\nTested on RZ/V2H(P) EVK with imx708 camera sensor.\n\nDan, could you re-test with Inline mode please ?\nI should have collected your fix that restored proper operations with\nInline.\n\nSigned-off-by: Jacopo Mondi <jacopo.mondi@ideasonboard.com>\n---\nChanges in v2:\n- Almost a complete rework of the CameraData which is now a class\n hierarchy.
