1 NVIDIA Tegra ACONNECT Bus
3 The Tegra ACONNECT bus is an AXI switch which is used to connnect various
4 components inside the Audio Processing Engine (APE). All CPU accesses to
5 the APE subsystem go through the ACONNECT via an APB to AXI wrapper.
8 - compatible: Must be "nvidia,tegra210-aconnect".
9 - clocks: Must contain the entries for the APE clock (TEGRA210_CLK_APE),
10 and APE interface clock (TEGRA210_CLK_APB2APE).
11 - clock-names: Must contain the names "ape" and "apb2ape" for the corresponding
13 - power-domains: Must contain a phandle that points to the audio powergate
14 (namely 'aud') for Tegra210.
15 - #address-cells: The number of cells used to represent physical base addresses
16 in the aconnect address space. Should be 1.
17 - #size-cells: The number of cells used to represent the size of an address
18 range in the aconnect address space. Should be 1.
19 - ranges: Mapping of the aconnect address space to the CPU address space.
21 All devices accessed via the ACONNNECT are described by child-nodes.
