Every patch was reviewed at this point and the whole thing looks good to go. Since this multi-part series has been going on for a while, it would be great to see it merged soon! Changes since v6: - Removed merged patches; - Added collected tags; - Rebased on the latest media tree; - Followed media/video pipeline helpers changes. Changes since v5: - Rebased on latest media tree; - Switched to using media_pad_remote_pad_first; - Switched to using media_pad_remote_pad_unique; - Declared variant const to avoid a warning. Changes since v4: - Removed the v4l2 controls handler from the driver; - Removed the info message about video device registration; - Fixed "literature" typos; - Moved patches dependent on the ISP driver to its dedicated series; - Rebased on the latest media tree; - Added collected tags; Changes since v3: - Updated Kconfig to follow the latest media-wide changes; - Rebased on latest changes to the driver (JPEG/sRGB colorspaces); - Added helper to get a single enabled link for an entity's pad, to replace source selection at link_validate time and select the remote source at stream on time instead; - Kept clock-managed regmap mmio; - Added collected review tags; - Various cosmetic cleanups; Changes since all-in-one v2: - Reworked capture video device registration, which stays in the main path. - Reworked async subdev handling with a dedicated structure holding the corresponding source to avoid matching in the driver; - Added mutex for mbus format serialization; - Remove useless else in link_validate; - Reworked commit logs to include missing information; - Cleaned up Kconfig, added PM dependency; - Moved platform-specific clock rate to of match data; - Added collected Reviewed-by tags; - Updated copyright years; Paul Kocialkowski (28): media: sun6i-csi: Add bridge v4l2 subdev with port management media: sun6i-csi: Rename sun6i_video to sun6i_csi_capture media: sun6i-csi: Add capture state using vsync for page flip media: sun6i-csi: Rework register definitions, invert misleading fields media: sun6i-csi: Add dimensions and format helpers to capture media: sun6i-csi: Implement address configuration without indirection media: sun6i-csi: Split stream sequences and irq code in capture media: sun6i-csi: Move power management to runtime pm in capture media: sun6i-csi: Move register configuration to capture media: sun6i-csi: Rework capture format management with helper media: sun6i-csi: Remove custom format helper and rework configure media: sun6i-csi: Add bridge dimensions and format helpers media: sun6i-csi: Get mbus code from bridge instead of storing it media: sun6i-csi: Tidy capture configure code media: sun6i-csi: Introduce bridge format structure, list and helper media: sun6i-csi: Introduce capture format structure, list and helper media: sun6i-csi: Configure registers from format tables media: sun6i-csi: Introduce format match structure, list and helper media: sun6i-csi: Implement capture link validation with logic media: sun6i-csi: Get bridge subdev directly in capture stream ops media: sun6i-csi: Move hardware control to the bridge media: sun6i-csi: Rename the capture video device to sun6i-csi-capture media: sun6i-csi: Cleanup headers and includes, update copyright lines media: sun6i-csi: Add support for MIPI CSI-2 to the bridge code media: sun6i-csi: Only configure capture when streaming media: sun6i-csi: Add extra checks to the interrupt routine media: sun6i-csi: Request a shared interrupt MAINTAINERS: Add myself as sun6i-csi maintainer and rename/move entry MAINTAINERS | 17 +- .../media/platform/sunxi/sun6i-csi/Makefile | 2 +- .../platform/sunxi/sun6i-csi/sun6i_csi.c | 751 +----------- .../platform/sunxi/sun6i-csi/sun6i_csi.h | 141 +-- .../sunxi/sun6i-csi/sun6i_csi_bridge.c | 844 +++++++++++++ .../sunxi/sun6i-csi/sun6i_csi_bridge.h | 69 ++ .../sunxi/sun6i-csi/sun6i_csi_capture.c | 1089 +++++++++++++++++ .../sunxi/sun6i-csi/sun6i_csi_capture.h | 88 ++ .../platform/sunxi/sun6i-csi/sun6i_csi_reg.h | 362 +++--- .../platform/sunxi/sun6i-csi/sun6i_video.c | 733 ----------- .../platform/sunxi/sun6i-csi/sun6i_video.h | 35 - 11 files changed, 2338 insertions(+), 1793 deletions(-) create mode 100644 drivers/media/platform/sunxi/sun6i-csi/sun6i_csi_bridge.c create mode 100644 drivers/media/platform/sunxi/sun6i-csi/sun6i_csi_bridge.h create mode 100644 drivers/media/platform/sunxi/sun6i-csi/sun6i_csi_capture.c create mode 100644 drivers/media/platform/sunxi/sun6i-csi/sun6i_csi_capture.h delete mode 100644 drivers/media/platform/sunxi/sun6i-csi/sun6i_video.c delete mode 100644 drivers/media/platform/sunxi/sun6i-csi/sun6i_video.h
