Overlays for the BananaPi M3 cameras are also provided as actual users of the camera pipeline on A83T. The corresponding drivers and dt bindings were merged a long time ago but this series was never actually picked up. It seems more than ready to be merged! Changes since v8: - Added collected review tags; - Added the overlays to be built as full dtbs. - Removed trailing whitespace. Changes since v7: - Added collected review tags; - Added interconnect properties to bindings; - Added compatible for device-tree overlays; - Moved mclk pin to sensor node in bpi-m3 overlays; - Removed duplicated assigned-clocks in bpi-m3 overlays. Changes since v6: - Rebased on top of the latest media tree, renamed dts to dtso for overlays. Changes since v5: - Added BananaPi M3 camera sensor support as device-tree overlays; - Cleaned-up OV8865 regulator definitions; - Always declared the internal links between CSI and MIPI CSI-2 on A83T in device-tree. Changes since v4: - Removed mbus bindings patch: an equivalent change was merged; - Added collected tags; - Rebased on latest media tree. Changes since v3: - Reordered v3s mbus compatible in binding; - Added collected tag; - Removed rejected interconnects fix. Changes since all-in-one v2: - Corrected mbus index used for the interconnects; - Used extended mbus binding and exported the DRAM clock for that; - Reworked the description of the core openfirmware change to give more insight about the situation. *** BLURB HERE *** Paul Kocialkowski (9): dt-bindings: media: sun6i-a31-csi: Add optional interconnect properties dt-bindings: media: sun6i-a31-isp: Add optional interconnect properties clk: sunxi-ng: v3s: Export MBUS and DRAM clocks to the public header ARM: dts: sun8i: v3s: Add mbus node to represent the interconnect ARM: dts: sun8i: v3s: Add nodes for MIPI CSI-2 support ARM: dts: sun8i: v3s: Add support for the ISP ARM: dts: sun8i: a83t: Add MIPI CSI-2 controller node ARM: dts: sun8i-a83t: Add BananaPi M3 OV5640 camera overlay ARM: dts: sun8i-a83t: Add BananaPi M3 OV8865 camera overlay .../media/allwinner,sun6i-a31-csi.yaml | 6 + .../media/allwinner,sun6i-a31-isp.yaml | 6 + arch/arm/boot/dts/allwinner/Makefile | 6 + .../sun8i-a83t-bananapi-m3-camera-ov5640.dtso | 115 +++++++++++++++++ .../sun8i-a83t-bananapi-m3-camera-ov8865.dtso | 101 +++++++++++++++ arch/arm/boot/dts/allwinner/sun8i-a83t.dtsi | 43 +++++++ arch/arm/boot/dts/allwinner/sun8i-v3s.dtsi | 121 ++++++++++++++++++ drivers/clk/sunxi-ng/ccu-sun8i-v3s.h | 4 - include/dt-bindings/clock/sun8i-v3s-ccu.h | 4 +- 9 files changed, 400 insertions(+), 6 deletions(-) create mode 100644 arch/arm/boot/dts/allwinner/sun8i-a83t-bananapi-m3-camera-ov5640.dtso create mode 100644 arch/arm/boot/dts/allwinner/sun8i-a83t-bananapi-m3-camera-ov8865.dtso
