1 QCOM BAM DMA controller
4 - compatible: must be one of the following:
5 * "qcom,bam-v1.4.0" for MSM8974, APQ8074 and APQ8084
6 * "qcom,bam-v1.3.0" for APQ8064, IPQ8064 and MSM8960
7 * "qcom,bam-v1.7.0" for MSM8916
8 - reg: Address range for DMA registers
9 - interrupts: Should contain the one interrupt shared by all channels
10 - #dma-cells: must be <1>, the cell in the dmas property of the client device
11 represents the channel number
12 - clocks: required clock
13 - clock-names: must contain "bam_clk" entry
14 - qcom,ee : indicates the active Execution Environment identifier (0-7) used in
16 - qcom,controlled-remotely : optional, indicates that the bam is controlled by
17 remote proccessor i.e. execution environment.
