This series adds the support of the Mediatek ISP3.0 found on some Mediatek SoCs such as the mt8365. The driver is divided into 2 parts: * SENINF: the sensor interface * CAMSV: this driver provides a path to bypass the SoC ISP so that image data coming from the SENINF can go directly into memory without any image processing. This allows the use of an external ISP or camera sensor directly. The SENINF driver is based on previous work done by Louis Kuo available as an RFC here: https://lore.kernel.org/all/20200708104023.3225-1-louis.kuo@xxxxxxxxxxxx/ This series depends on the following series for the phy [1] Changes in v6: - remove unneeded "link" tag from commits bindings: - remove labels from example node - remove complexity for phy and phy-name properties driver: - fix some comments from CK : - remove unneeded variables - rename irqlock to buf_list_lock for clarity - remove unneeded lock/unlock around hw_enable/hw_disable - Link to v5: https://lore.kernel.org/r/20240704-add-mtk-isp-3-0-support-v5-0-bfccccc5ec21@xxxxxxxxxxxx Changes on v5: drivers: - rebase on 6.10-rc1 - fix various comments from all reviews (mostly style issues and minor code refactor) - add a function to calculate the clock divider for the master sensor clock: NOTE: setting this register seems to have no effect at all, currently checking with mediatek apps engineer (OOO until 17/04) bindings: - camsv: update description - seninf: fix phy definition and example indentation - use generic name for node example dts: - sort nodes by addresses - use lower case for hexadecimal Changes in v4: - fix suspend/resume deadlock - fix various locking issues reported by Laurent Pinchart on v3 - run LOCKDEP - add missing include reported by kernel-test-robot for non mediatek arch and COMPILE_TEST=y - use atomic poll inside mtk_camsv30_setup - drop second lane support as it was not used - remove useless members in structs - fix media entity initialization - initialize correct pad for camsv video device - add isp support in mt8365.dtsi - rebase on 6.7 Changes in v3: - fix a lot of formatting issues/coding style issues found in camsv/seninf reported by Angelo on v2 - fix camsv/seninf binding file error reported by Rob Changes in v2: - renamed clock `cam_seninf` to `camsys` - renamed clock `top_mux_seninf` to `top_mux` - moved phy properties from port nodes to top level - remove patternProperties - specify power management dependency in the cover letter description to fix missing include in dt-binding example - change '$ref' properties on some endpoint nodes from '$ref: video-interfaces.yaml#' to '$ref: /schemas/graph.yaml#/$defs/endpoint-base' where applicable Best Julien Stephan Signed-off-by: Julien Stephan <jstephan@xxxxxxxxxxxx> --- Julien Stephan (1): arm64: dts: mediatek: mt8365: Add support for camera Louis Kuo (2): dt-bindings: media: add mediatek ISP3.0 sensor interface media: platform: mediatek: isp_30: add mediatek ISP3.0 sensor interface Phi-bang Nguyen (2): dt-bindings: media: add mediatek ISP3.0 camsv media: platform: mediatek: isp_30: add mediatek ISP3.0 camsv .../bindings/media/mediatek,mt8365-camsv.yaml | 109 ++ .../bindings/media/mediatek,mt8365-seninf.yaml | 259 ++++ MAINTAINERS | 10 + arch/arm64/boot/dts/mediatek/mt8365.dtsi | 125 ++ drivers/media/platform/mediatek/Kconfig | 1 + drivers/media/platform/mediatek/Makefile | 1 + drivers/media/platform/mediatek/isp/Kconfig | 2 + drivers/media/platform/mediatek/isp/Makefile | 3 + drivers/media/platform/mediatek/isp/isp_30/Kconfig | 35 + .../media/platform/mediatek/isp/isp_30/Makefile | 4 + .../platform/mediatek/isp/isp_30/camsv/Makefile | 7 + .../platform/mediatek/isp/isp_30/camsv/mtk_camsv.c | 327 ++++ .../platform/mediatek/isp/isp_30/camsv/mtk_camsv.h | 192 +++ .../mediatek/isp/isp_30/camsv/mtk_camsv30_hw.c | 413 +++++ .../mediatek/isp/isp_30/camsv/mtk_camsv30_regs.h | 60 + .../mediatek/isp/isp_30/camsv/mtk_camsv_video.c | 742 +++++++++ .../platform/mediatek/isp/isp_30/seninf/Makefile | 5 + .../mediatek/isp/isp_30/seninf/mtk_seninf.c | 1576 ++++++++++++++++++++ .../mediatek/isp/isp_30/seninf/mtk_seninf_reg.h | 117 ++ 19 files changed, 3988 insertions(+) --- base-commit: 99b9aaac4abdf30968b2ce9c9848951290fbde92 change-id: 20240704-add-mtk-isp-3-0-support-a08a978cac36 Best regards, -- Julien Stephan <jstephan@xxxxxxxxxxxx>
