- * "qcom,bam-v1.4.0" for MSM8974, APQ8074 and APQ8084
- * "qcom,bam-v1.3.0" for APQ8064, IPQ8064 and MSM8960
- * "qcom,bam-v1.7.0" for MSM8916
-- reg: Address range for DMA registers
-- interrupts: Should contain the one interrupt shared by all channels
-- #dma-cells: must be <1>, the cell in the dmas property of the client device
- represents the channel number
-- clocks: required clock
-- clock-names: must contain "bam_clk" entry
-- qcom,ee : indicates the active Execution Environment identifier (0-7) used in
- the secure world.
-- qcom,controlled-remotely : optional, indicates that the bam is controlled by
- remote proccessor i.e. execution environment.
-- qcom,powered-remotely : optional, indicates that the bam is powered up by
- a remote processor but must be initialized by the local processor.
-- num-channels : optional, indicates supported number of DMA channels in a
