   1 * MediaTek JPEG Encoder
   2
   3 MediaTek JPEG Encoder is the JPEG encode hardware present in MediaTek SoCs
   4
   5 Required properties:
   6 - compatible : "mediatek,mt2701-jpgenc"
   7   followed by "mediatek,mtk-jpgenc"
   8 - reg : physical base address of the JPEG encoder registers and length of
   9   memory mapped region.
  10 - interrupts : interrupt number to the interrupt controller.
  11 - clocks: device clocks, see
  12   Documentation/devicetree/bindings/clock/clock-bindings.txt for details.
  13 - clock-names: must contain "jpgenc". It is the clock of JPEG encoder.
  14 - power-domains: a phandle to the power domain, see
  15   Documentation/devicetree/bindings/power/power_domain.txt for details.
  16 - mediatek,larb: must contain the local arbiters in the current SoCs, see
  17   Documentation/devicetree/bindings/memory-controllers/mediatek,smi-larb.txt
  18   for details.
  19 - iommus: should point to the respective IOMMU block with master port as
  20   argument, see Documentation/devicetree/bindings/iommu/mediatek,iommu.txt
  21   for details.
