Most non-dt patches still need reviewing but should be pretty straightforward. The ISP driver itself was thoroughly discussed and the concerns that were raised about it have been resolved. Since this multi-part series has been going on for a while, it would be great to see it merged soon! Changes since v7: - Rebased on the latest media tree; - Followed media/video pipeline helpers changes. Changes since v6: - Added a per-compatible check for the required port in dt binding; - Reworded ISP output port description in dt binding; - Reversed ISP detection order to have fwnode first; - Removed info print when ISP link is detected; - Added warn print when ISP is linked but not enabled in config; - Fixed sun6i_csi_isp_detect return type; - Removed useless initialization in sun6i_csi_isp_detect; - Fixed typo in sun6i_csi_isp_detect; - Added collected tags; Changes since v5: - Rebased on latest media tree; - Added collected tag; - Switched to using media_pad_remote_pad_first; - Switched to using media_pad_remote_pad_unique. Changes since v4: - Fixed device-tree binding indent-align; - Added collected tag; - Rebased on latest media tree; Changes since v3: - Removed the v4l2 controls handler from the driver; - Added variant structure for table sizes; - Removed the info message about video device registration; - Removed comments in uAPI header; - Used '/schemas/graph.yaml#/properties/port' whenever possible in bindings; - Added CSI patches dependent on the ISP driver; - Rebased on the latest media tree; Changes since all-in-one v2: - Updated Kconfig to follow the latest media-wide changes; - Reworked async subdev handling with a dedicated structure holding the corresponding source to avoid matching in the driver; - Switched to clock-managed regmap mmio; - Used 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; - Added mutex for mbus format serialization; - Used endpoint-base instead of video-interface for "internal" endpoints in device-tree schema; - Added TODO with unstaging requirements; - Various cosmetic cleanups; - Updated copyright years; Paul Kocialkowski (6): dt-bindings: media: Add Allwinner A31 ISP bindings documentation dt-bindings: media: sun6i-a31-csi: Add internal output port to the ISP staging: media: Add support for the Allwinner A31 ISP MAINTAINERS: Add entry for the Allwinner A31 ISP driver media: sun6i-csi: Detect the availability of the ISP media: sun6i-csi: Add support for hooking to the isp devices .../media/allwinner,sun6i-a31-csi.yaml | 4 + .../media/allwinner,sun6i-a31-isp.yaml | 101 +++ MAINTAINERS | 9 + .../platform/sunxi/sun6i-csi/sun6i_csi.c | 75 +- .../platform/sunxi/sun6i-csi/sun6i_csi.h | 10 + .../sunxi/sun6i-csi/sun6i_csi_bridge.c | 32 +- .../sunxi/sun6i-csi/sun6i_csi_capture.c | 19 +- .../sunxi/sun6i-csi/sun6i_csi_capture.h | 1 + drivers/staging/media/sunxi/Kconfig | 1 + drivers/staging/media/sunxi/Makefile | 1 + drivers/staging/media/sunxi/sun6i-isp/Kconfig | 15 + .../staging/media/sunxi/sun6i-isp/Makefile | 4 + .../staging/media/sunxi/sun6i-isp/TODO.txt | 6 + .../staging/media/sunxi/sun6i-isp/sun6i_isp.c | 555 +++++++++++++ .../staging/media/sunxi/sun6i-isp/sun6i_isp.h | 90 +++ .../media/sunxi/sun6i-isp/sun6i_isp_capture.c | 742 ++++++++++++++++++ .../media/sunxi/sun6i-isp/sun6i_isp_capture.h | 78 ++ .../media/sunxi/sun6i-isp/sun6i_isp_params.c | 566 +++++++++++++ .../media/sunxi/sun6i-isp/sun6i_isp_params.h | 52 ++ .../media/sunxi/sun6i-isp/sun6i_isp_proc.c | 577 ++++++++++++++ .../media/sunxi/sun6i-isp/sun6i_isp_proc.h | 66 ++ .../media/sunxi/sun6i-isp/sun6i_isp_reg.h | 275 +++++++ .../sunxi/sun6i-isp/uapi/sun6i-isp-config.h | 43 + 23 files changed, 3309 insertions(+), 13 deletions(-) create mode 100644 Documentation/devicetree/bindings/media/allwinner,sun6i-a31-isp.yaml create mode 100644 drivers/staging/media/sunxi/sun6i-isp/Kconfig create mode 100644 drivers/staging/media/sunxi/sun6i-isp/Makefile create mode 100644 drivers/staging/media/sunxi/sun6i-isp/TODO.txt create mode 100644 drivers/staging/media/sunxi/sun6i-isp/sun6i_isp.c create mode 100644 drivers/staging/media/sunxi/sun6i-isp/sun6i_isp.h create mode 100644 drivers/staging/media/sunxi/sun6i-isp/sun6i_isp_capture.c create mode 100644 drivers/staging/media/sunxi/sun6i-isp/sun6i_isp_capture.h create mode 100644 drivers/staging/media/sunxi/sun6i-isp/sun6i_isp_params.c create mode 100644 drivers/staging/media/sunxi/sun6i-isp/sun6i_isp_params.h create mode 100644 drivers/staging/media/sunxi/sun6i-isp/sun6i_isp_proc.c create mode 100644 drivers/staging/media/sunxi/sun6i-isp/sun6i_isp_proc.h create mode 100644 drivers/staging/media/sunxi/sun6i-isp/sun6i_isp_reg.h create mode 100644 drivers/staging/media/sunxi/sun6i-isp/uapi/sun6i-isp-config.h
