* 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,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.
|
||
|
|
- iommus: should point to the respective IOMMU block with master port as
|
||
|
|
argument, see Documentation/devicetree/bindings/iommu/mediatek,iommu.txt
|
||
|
|
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>;
|
||
|
|
iommus = <&iommu MT2701_M4U_PORT_JPGDEC_WDMA>,
|
||
|
|
<&iommu MT2701_M4U_PORT_JPGDEC_BSDMA>;
|
||
|
|
};
