1QCOM BAM DMA controller 2 3Required properties: 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 15 the secure world. 16 17Example: 18 19 uart-bam: dma@f9984000 = { 20 compatible = "qcom,bam-v1.4.0"; 21 reg = <0xf9984000 0x15000>; 22 interrupts = <0 94 0>; 23 clocks = <&gcc GCC_BAM_DMA_AHB_CLK>; 24 clock-names = "bam_clk"; 25 #dma-cells = <1>; 26 qcom,ee = <0>; 27 }; 28 29DMA clients must use the format described in the dma.txt file, using a two cell 30specifier for each channel. 31 32Example: 33 serial@f991e000 { 34 compatible = "qcom,msm-uart"; 35 reg = <0xf991e000 0x1000> 36 <0xf9944000 0x19000>; 37 interrupts = <0 108 0>; 38 clocks = <&gcc GCC_BLSP1_UART2_APPS_CLK>, 39 <&gcc GCC_BLSP1_AHB_CLK>; 40 clock-names = "core", "iface"; 41 42 dmas = <&uart-bam 0>, <&uart-bam 1>; 43 dma-names = "rx", "tx"; 44 }; 45
