QCOM BAM DMA controller Required properties: - compatible: must be one of the following: * "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. Example: uart-bam: dma@f9984000 = { compatible = "qcom,bam-v1.4.0"; reg = <0xf9984000 0x15000>; interrupts = <0 94 0>; clocks = <&gcc GCC_BAM_DMA_AHB_CLK>; clock-names = "bam_clk"; #dma-cells = <1>; qcom,ee = <0>; }; DMA clients must use the format described in the dma.txt file, using a two cell specifier for each channel. Example: serial@f991e000 { compatible = "qcom,msm-uart"; reg = <0xf991e000 0x1000> <0xf9944000 0x19000>; interrupts = <0 108 0>; clocks = <&gcc GCC_BLSP1_UART2_APPS_CLK>, <&gcc GCC_BLSP1_AHB_CLK>; clock-names = "core", "iface"; dmas = <&uart-bam 0>, <&uart-bam 1>; dma-names = "rx", "tx"; };
