| * Mediatek JPEG Decoder |
| |
| Mediatek JPEG Decoder is the JPEG decode hardware present in Mediatek SoCs |
| |
| Required properties: |
| - compatible : must be one of the following string: |
| "mediatek,mt8173-jpgdec" |
| "mediatek,mt7623-jpgdec", "mediatek,mt2701-jpgdec" |
| "mediatek,mt2701-jpgdec" |
| - reg : physical base address of the jpeg decoder registers and length of |
| memory mapped region. |
| - interrupts : interrupt number to the interrupt controller. |
| - clocks: device clocks, see |
| Documentation/devicetree/bindings/clock/clock-bindings.txt for details. |
| - clock-names: must contain "jpgdec-smi" and "jpgdec". |
| - power-domains: a phandle to the power domain, see |
| Documentation/devicetree/bindings/power/power_domain.txt for details. |
| - mediatek,larb: must contain the local arbiters in the current Socs, see |
| Documentation/devicetree/bindings/memory-controllers/mediatek,smi-larb.yaml |
| for details. |
| - iommus: should point to the respective IOMMU block with master port as |
| argument, see Documentation/devicetree/bindings/iommu/mediatek,iommu.yaml |
| for details. |
| |
| Example: |
| jpegdec: jpegdec@15004000 { |
| compatible = "mediatek,mt2701-jpgdec"; |
| reg = <0 0x15004000 0 0x1000>; |
| interrupts = <GIC_SPI 143 IRQ_TYPE_LEVEL_LOW>; |
| clocks = <&imgsys CLK_IMG_JPGDEC_SMI>, |
| <&imgsys CLK_IMG_JPGDEC>; |
| clock-names = "jpgdec-smi", |
| "jpgdec"; |
| power-domains = <&scpsys MT2701_POWER_DOMAIN_ISP>; |
| mediatek,larb = <&larb2>; |
| iommus = <&iommu MT2701_M4U_PORT_JPGDEC_WDMA>, |
| <&iommu MT2701_M4U_PORT_JPGDEC_BSDMA>; |
