* Qualcomm Technologies, Inc. MSM JPEG DMA

Jpeg dma hardware block.

Jpeg dma can replicate and downscale yuv frames.
Supported formats: Monochrome, NV12 and NV21.

Required properties:
- compatible : "qcom,jpegdma".
- reg : offset and length of the register set of jpeg dma device and
    vbif device for the jpeg dma operating in compatible mode.
- reg-names : should specify relevant names to each reg property defined.
- interrupts : should contain the jpeg interrupt.
- interrupt-names : should specify relevant names to each interrupts
  property defined.
- mmagic-vdd-supply: phandle to GDSC regulator controlling mmagic.
- camss-vdd-supply: phandle to GDSC regulator controlling camss.
- clock-names : names of clocks required for the device.
- clocks : clocks required for the device.
- qcom,clock-rates: should specify clock rates in Hz to each clocks
    property defined.
- qcom,max-ds-factor: should specify the max dma downscale factor,
    supported by HW.
- Refer to "Documentation/devicetree/bindings/arm/msm/msm_bus.txt" for
	below optional properties:
	- qcom,msm-bus,name
	- qcom,msm-bus,num-cases
	- qcom,msm-bus,num-paths
	- qcom,msm-bus,vectors-KBps

Optional properties:
- qcom,vbif-reg-settings: relative address offsets and value pairs for VBIF registers.
- qcom,qos-reg-settings: relative address offsets and value pairs for QoS registers.
- qcom,prefetch-reg-settings: relative address offsets and value pairs for
  MMU prefetch registers.
