Add binding document for Venus video encoder/decoder driver Cc: Rob Herring <robh+dt@xxxxxxxxxx> Cc: Mark Rutland <mark.rutland@xxxxxxx> Cc: devicetree@xxxxxxxxxxxxxxx Signed-off-by: Stanimir Varbanov <stanimir.varbanov@xxxxxxxxxx> --- Rob, I have removed vmem clocks, interrupts and reg properties for vmem thing. Probably I will come with a separate platform driver fro that and pass the video memory DT node as phandle. .../devicetree/bindings/media/qcom,venus.txt | 82 ++++++++++++++++++++++ 1 file changed, 82 insertions(+) create mode 100644 Documentation/devicetree/bindings/media/qcom,venus.txt diff --git a/Documentation/devicetree/bindings/media/qcom,venus.txt b/Documentation/devicetree/bindings/media/qcom,venus.txt new file mode 100644 index 000000000000..a64b4ea1ebba --- /dev/null +++ b/Documentation/devicetree/bindings/media/qcom,venus.txt @@ -0,0 +1,82 @@ +* Qualcomm Venus video encode/decode accelerator + +- compatible: + Usage: required + Value type: <stringlist> + Definition: Value should contain one of: + - "qcom,msm8916-venus" + - "qcom,msm8996-venus" +- reg: + Usage: required + Value type: <prop-encoded-array> + Definition: Register ranges as listed in the reg-names property. +- reg-names: + Usage: required + Value type: <stringlist> + Definition: Should contain following entries: + - "base" Venus register base +- interrupts: + Usage: required + Value type: <prop-encoded-array> + Definition: Should contain interrupts as listed in the interrupt-names + property. +- interrupt-names: + Usage: required + Value type: <stringlist> + Definition: Should contain following entries: + - "venus" Venus interrupt line +- clocks: + Usage: required + Value type: <prop-encoded-array> + Definition: A List of phandle and clock specifier pairs as listed + in clock-names property. +- clock-names: + Usage: required + Value type: <stringlist> + Definition: Should contain the following entries: + - "core" Core video accelerator clock + - "iface" Video accelerator AHB clock + - "bus" Video accelerator AXI clock +- clock-names: + Usage: required for msm8996 + Value type: <stringlist> + Definition: Should contain the following entries: + - "subcore0" Subcore0 video accelerator clock + - "subcore1" Subcore1 video accelerator clock + - "mmssnoc_axi" Multimedia subsystem NOC AXI clock + - "mmss_mmagic_iface" Multimedia subsystem MMAGIC AHB clock + - "mmss_mmagic_mbus" Multimedia subsystem MMAGIC MAXI clock + - "mmagic_video_bus" MMAGIC video AXI clock + - "video_mbus" Video MAXI clock +- power-domains: + Usage: required + Value type: <prop-encoded-array> + Definition: A phandle and power domain specifier pairs to the + power domain which is responsible for collapsing + and restoring power to the peripheral. +- rproc: + Usage: required + Value type: <prop-encoded-array> + Definition: A phandle to remote processor responsible for + firmware loading and processor booting. + +- iommus: + Usage: required + Value type: <prop-encoded-array> + Definition: A list of phandle and IOMMU specifier pairs. + +* An Example + video-codec@1d00000 { + compatible = "qcom,msm8916-venus"; + reg = <0x01d00000 0xff000>; + reg-names = "base"; + interrupts = <GIC_SPI 44 IRQ_TYPE_LEVEL_HIGH>; + interrupt-names = "venus"; + clocks = <&gcc GCC_VENUS0_VCODEC0_CLK>, + <&gcc GCC_VENUS0_AHB_CLK>, + <&gcc GCC_VENUS0_AXI_CLK>; + clock-names = "core", "iface", "bus"; + power-domains = <&gcc VENUS_GDSC>; + rproc = <&venus_rproc>; + iommus = <&apps_iommu 5>; + }; -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
