* MediaTek JPEG Encoder
|
|
|
|
MediaTek JPEG Encoder is the JPEG encode hardware present in MediaTek SoCs
|
|
|
|
Required properties:
|
|
- compatible : "mediatek,mt2701-jpgenc"
|
|
followed by "mediatek,mtk-jpgenc"
|
|
- reg : physical base address of the JPEG encoder 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 "jpgenc". It is the clock of JPEG encoder.
|
|
- 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:
|
|
jpegenc: jpegenc@1500a000 {
|
|
compatible = "mediatek,mt2701-jpgenc",
|
|
"mediatek,mtk-jpgenc";
|
|
reg = <0 0x1500a000 0 0x1000>;
|
|
interrupts = <GIC_SPI 141 IRQ_TYPE_LEVEL_LOW>;
|
|
clocks = <&imgsys CLK_IMG_VENC>;
|
|
clock-names = "jpgenc";
|
|
power-domains = <&scpsys MT2701_POWER_DOMAIN_ISP>;
|
|
mediatek,larb = <&larb2>;
|
|
iommus = <&iommu MT2701_M4U_PORT_JPGENC_RDMA>,
|
|
<&iommu MT2701_M4U_PORT_JPGENC_BSDMA>;
|
|
};
