The support is partial in that it implements CSIPHY, CSID, and partial VFE support. The Titan generation of the ISP diverges a fair amount from the design of the previous architecture generation, CAMSS. As a result some pretty invasive refactoring is done in this series. It also means that at this time we're unable to implement support for all of the IP blocks contained. This is due to a combination of legal considerations with respect to the IP and its owner Qualcomm and time & man hour constrains on the Linaro side. The CSIPHY (CSI Physical Layer) & CSID (CSI Decoder) support is complete, but the VFE (Video Front End, which is referred to as IFE (Image Front End) in the Titan generation of ISPs) only has support for the RDI (Raw Dump Interface) which allows the raw output of the CSID to be written to memory. The 2nd interface implemented in the VFE silicon is the PIX interface, and camss does not support it for this generation of ISPs. The reason for this is that the PIX interface is used for sending image data to the BPS (Bayer Processing Section) & IPE (Image Processing Engine), but both of these units are beyond the scope of enabling basic ISP functionality for the SDM845. Since the Titan architecture generation diverges quite a bit from the CAMSS generation, a lot of pretty major refactoring is carried out in this series. Both the CSID & VFE core paths are made more general and hardware version specific parts are broken out. The CSIPHY didn't require quite as radical changes and therefore keeps its current form. Tested on: - Qcom RB3 / db845c + camera mezzanine, which is SDM845 based - db410c + D3 Camera mezzanine, which is APQ8016 based Branch: - https://git.linaro.org/people/robert.foss/linux.git/log/?h=camss_sdm845_v1 - https://git.linaro.org/people/robert.foss/linux.git/log/?h=camss_sdm845_v2 - https://git.linaro.org/people/robert.foss/linux.git/log/?h=camss_sdm845_v3 - https://git.linaro.org/people/robert.foss/linux.git/log/?h=camss_sdm845_v4 - https://git.linaro.org/people/robert.foss/linux.git/log/?h=camss_sdm845_v5 - https://git.linaro.org/people/robert.foss/linux.git/log/?h=camss_sdm845_v6 - https://git.linaro.org/people/robert.foss/linux.git/log/?h=camss_sdm845_v7 - https://git.linaro.org/people/robert.foss/linux.git/log/?h=camss_sdm845_v8 Robert Foss (22): media: camss: Fix vfe_isr_comp_done() documentation media: camss: Fix vfe_isr comment typo media: camss: Replace trace_printk() with dev_dbg() media: camss: Add CAMSS_845 camss version media: camss: Make ISPIF subdevice optional media: camss: Refactor VFE HW version support media: camss: Add support for VFE hardware version Titan 170 media: camss: Add missing format identifiers media: camss: Refactor CSID HW version support media: camss: Add support for CSID hardware version Titan 170 media: camss: Add support for CSIPHY hardware version Titan 170 media: camss: Refactor VFE power domain toggling media: camss: Enable SDM845 dt-bindings: media: camss: Add qcom,msm8916-camss binding dt-bindings: media: camss: Add qcom,msm8996-camss binding dt-bindings: media: camss: Add qcom,sdm660-camss binding dt-bindings: media: camss: Add qcom,sdm845-camss binding MAINTAINERS: Change CAMSS documentation to use dtschema bindings media: dt-bindings: media: Remove qcom,camss documentation arm64: dts: sdm845: Add CAMSS ISP node arm64: dts: sdm845-db845c: Configure regulators for camss node arm64: dts: sdm845-db845c: Enable ov8856 sensor and connect to ISP .../devicetree/bindings/media/qcom,camss.txt | 236 ---- .../bindings/media/qcom,msm8916-camss.yaml | 256 ++++ .../bindings/media/qcom,msm8996-camss.yaml | 387 ++++++ .../bindings/media/qcom,sdm660-camss.yaml | 398 ++++++ .../bindings/media/qcom,sdm845-camss.yaml | 371 +++++ MAINTAINERS | 2 +- arch/arm64/boot/dts/qcom/sdm845-db845c.dts | 23 +- arch/arm64/boot/dts/qcom/sdm845.dtsi | 135 ++ drivers/media/platform/qcom/camss/Makefile | 6 + .../platform/qcom/camss/camss-csid-170.c | 599 +++++++++ .../platform/qcom/camss/camss-csid-4-1.c | 328 +++++ .../platform/qcom/camss/camss-csid-4-7.c | 404 ++++++ .../platform/qcom/camss/camss-csid-gen1.h | 27 + .../platform/qcom/camss/camss-csid-gen2.h | 39 + .../media/platform/qcom/camss/camss-csid.c | 627 +-------- .../media/platform/qcom/camss/camss-csid.h | 161 ++- .../qcom/camss/camss-csiphy-3ph-1-0.c | 179 ++- .../media/platform/qcom/camss/camss-csiphy.c | 66 +- .../media/platform/qcom/camss/camss-ispif.c | 119 +- .../media/platform/qcom/camss/camss-ispif.h | 3 +- .../media/platform/qcom/camss/camss-vfe-170.c | 786 +++++++++++ .../media/platform/qcom/camss/camss-vfe-4-1.c | 144 +- .../media/platform/qcom/camss/camss-vfe-4-7.c | 277 ++-- .../media/platform/qcom/camss/camss-vfe-4-8.c | 1195 +++++++++++++++++ .../platform/qcom/camss/camss-vfe-gen1.c | 742 ++++++++++ .../platform/qcom/camss/camss-vfe-gen1.h | 117 ++ drivers/media/platform/qcom/camss/camss-vfe.c | 847 +----------- drivers/media/platform/qcom/camss/camss-vfe.h | 128 +- .../media/platform/qcom/camss/camss-video.c | 52 + drivers/media/platform/qcom/camss/camss.c | 410 +++++- drivers/media/platform/qcom/camss/camss.h | 15 +- 31 files changed, 7027 insertions(+), 2052 deletions(-) delete mode 100644 Documentation/devicetree/bindings/media/qcom,camss.txt create mode 100644 Documentation/devicetree/bindings/media/qcom,msm8916-camss.yaml create mode 100644 Documentation/devicetree/bindings/media/qcom,msm8996-camss.yaml create mode 100644 Documentation/devicetree/bindings/media/qcom,sdm660-camss.yaml create mode 100644 Documentation/devicetree/bindings/media/qcom,sdm845-camss.yaml create mode 100644 drivers/media/platform/qcom/camss/camss-csid-170.c create mode 100644 drivers/media/platform/qcom/camss/camss-csid-4-1.c create mode 100644 drivers/media/platform/qcom/camss/camss-csid-4-7.c create mode 100644 drivers/media/platform/qcom/camss/camss-csid-gen1.h create mode 100644 drivers/media/platform/qcom/camss/camss-csid-gen2.h create mode 100644 drivers/media/platform/qcom/camss/camss-vfe-170.c create mode 100644 drivers/media/platform/qcom/camss/camss-vfe-4-8.c create mode 100644 drivers/media/platform/qcom/camss/camss-vfe-gen1.c create mode 100644 drivers/media/platform/qcom/camss/camss-vfe-gen1.h
