-QCOM ADM DMA Controller
-
-Required properties:
-- compatible: must contain "qcom,adm" for IPQ/APQ8064 and MSM8960
-- reg: Address range for DMA registers
-- interrupts: Should contain one interrupt shared by all channels
-- #dma-cells: must be <2>.  First cell denotes the channel number.  Second cell
-  denotes CRCI (client rate control interface) flow control assignment.
-- clocks: Should contain the core clock and interface clock.
-- clock-names: Must contain "core" for the core clock and "iface" for the
-  interface clock.
-- resets: Must contain an entry for each entry in reset names.
-- reset-names: Must include the following entries:
-  - clk
-  - c0
-  - c1
-  - c2
-- qcom,ee: indicates the security domain identifier used in the secure world.
-
-Example:
-		adm_dma: dma@18300000 {
-			compatible = "qcom,adm";
-			reg = <0x18300000 0x100000>;
-			interrupts = <0 170 0>;
-			#dma-cells = <2>;
-
-			clocks = <&gcc ADM0_CLK>, <&gcc ADM0_PBUS_CLK>;
-			clock-names = "core", "iface";
-
-			resets = <&gcc ADM0_RESET>,
-				<&gcc ADM0_C0_RESET>,
-				<&gcc ADM0_C1_RESET>,
-				<&gcc ADM0_C2_RESET>;
-			reset-names = "clk", "c0", "c1", "c2";
-			qcom,ee = <0>;
-		};
-
-DMA clients must use the format descripted in the dma.txt file, using a three
-cell specifier for each channel.
-
-Each dmas request consists of 3 cells:
- 1. phandle pointing to the DMA controller
- 2. channel number
- 3. CRCI assignment, if applicable.  If no CRCI flow control is required, use 0.
-    The CRCI is used for flow control.  It identifies the peripheral device that
-    is the source/destination for the transferred data.
-
-Example:
-
-	spi4: spi@1a280000 {
-		spi-max-frequency = <50000000>;
-
-		pinctrl-0 = <&spi_pins>;
-		pinctrl-names = "default";
-
-		cs-gpios = <&qcom_pinmux 20 0>;
-
-		dmas = <&adm_dma 6 9>,
-			<&adm_dma 5 10>;
-		dma-names = "rx", "tx";
-	};
