2
3Mediatek JPEG Decoder is the JPEG decode hardware present in Mediatek SoCs
4
5Required properties:
6- compatible : must be one of the following string:
7 "mediatek,mt8173-jpgdec"
Matthias Brugger1892e122018-10-03 11:09:11 +02008 "mediatek,mt7623-jpgdec", "mediatek,mt2701-jpgdec"
Rick Chang84a677422016-12-14 06:04:47 -02009 "mediatek,mt2701-jpgdec"
10- reg : physical base address of the jpeg decoder registers and length of
11 memory mapped region.
12- interrupts : interrupt number to the interrupt controller.
13- clocks: device clocks, see
14 Documentation/devicetree/bindings/clock/clock-bindings.txt for details.
15- clock-names: must contain "jpgdec-smi" and "jpgdec".
16- power-domains: a phandle to the power domain, see
17 Documentation/devicetree/bindings/power/power_domain.txt for details.
18- mediatek,larb: must contain the local arbiters in the current Socs, see
19 Documentation/devicetree/bindings/memory-controllers/mediatek,smi-larb.txt
20 for details.
21- iommus: should point to the respective IOMMU block with master port as
22 argument, see Documentation/devicetree/bindings/iommu/mediatek,iommu.txt
23 for details.

26 jpegdec: jpegdec@15004000 {
27 compatible = "mediatek,mt2701-jpgdec";
28 reg = <0 0x15004000 0 0x1000>;
29 interrupts = <GIC_SPI 143 IRQ_TYPE_LEVEL_LOW>;
30 clocks = <&imgsys CLK_IMG_JPGDEC_SMI>,
31 <&imgsys CLK_IMG_JPGDEC>;
32 clock-names = "jpgdec-smi",
33 "jpgdec";
34 power-domains = <&scpsys MT2701_POWER_DOMAIN_ISP>;
35 mediatek,larb = <&larb2>;
36 iommus = <&iommu MT2701_M4U_PORT_JPGDEC_WDMA>,
37 <&iommu MT2701_M4U_PORT_JPGDEC_BSDMA>;
