1* NVIDIA Tegra Audio DMA (ADMA) controller
2
3The Tegra Audio DMA controller that is used for transferring data
4between system memory and the Audio Processing Engine (APE).
5
6Required properties:
7- compatible: Must be "nvidia,tegra210-adma".
8- reg: Should contain DMA registers location and length. This should be
9  a single entry that includes all of the per-channel registers in one
10  contiguous bank.
11- interrupts: Should contain all of the per-channel DMA interrupts in
12  ascending order with respect to the DMA channel index.
13- clocks: Must contain one entry for the ADMA module clock
14  (TEGRA210_CLK_D_AUDIO).
15- clock-names: Must contain the name "d_audio" for the corresponding
16  'clocks' entry.
17- #dma-cells : Must be 1. The first cell denotes the receive/transmit
18  request number and should be between 1 and the maximum number of
19  requests supported. This value corresponds to the RX/TX_REQUEST_SELECT
20  fields in the ADMA_CHn_CTRL register.
