-* NVIDIA Tegra Audio DMA (ADMA) controller
-
-The Tegra Audio DMA controller that is used for transferring data
-between system memory and the Audio Processing Engine (APE).
-
-Required properties:
-- compatible: Should contain one of the following:
- - "nvidia,tegra210-adma": for Tegra210
- - "nvidia,tegra186-adma": for Tegra186 and Tegra194
-- reg: Should contain DMA registers location and length. This should be
- a single entry that includes all of the per-channel registers in one
- contiguous bank.
-- interrupts: Should contain all of the per-channel DMA interrupts in
- ascending order with respect to the DMA channel index.
-- clocks: Must contain one entry for the ADMA module clock
- (TEGRA210_CLK_D_AUDIO).
-- clock-names: Must contain the name "d_audio" for the corresponding
- 'clocks' entry.
-- #dma-cells : Must be 1. The first cell denotes the receive/transmit
- request number and should be between 1 and the maximum number of
- requests supported. This value corresponds to the RX/TX_REQUEST_SELECT
- fields in the ADMA_CHn_CTRL register.
-
-
-Example:
-
-adma: dma@702e2000 {
- compatible = "nvidia,tegra210-adma";
- reg = <0x0 0x702e2000 0x0 0x2000>;
- interrupt-parent = <&tegra_agic>;
- interrupts = <GIC_SPI 24 IRQ_TYPE_LEVEL_HIGH>,
- <GIC_SPI 25 IRQ_TYPE_LEVEL_HIGH>,
- <GIC_SPI 26 IRQ_TYPE_LEVEL_HIGH>,
- <GIC_SPI 27 IRQ_TYPE_LEVEL_HIGH>,
- <GIC_SPI 28 IRQ_TYPE_LEVEL_HIGH>,
- <GIC_SPI 29 IRQ_TYPE_LEVEL_HIGH>,

- <GIC_SPI 43 IRQ_TYPE_LEVEL_HIGH>,
- <GIC_SPI 44 IRQ_TYPE_LEVEL_HIGH>,
