It has 13 external interfaces such as I2S, DMIC, DSPK. It interfaces with ADMA 14 engine through ADMAIF. 15 16maintainers: 17 - Jon Hunter <jonathanh@nvidia.com> 18 - Sameer Pujar <spujar@nvidia.com> 19 20properties: 21 $nodename: 22 pattern: "^ahub@[0-9a-f]*$" 23 24 compatible: 25 oneOf: 26 - enum: 27 - nvidia,tegra210-ahub 28 - nvidia,tegra186-ahub 29 - nvidia,tegra234-ahub 30 - items: 31 - const: nvidia,tegra194-ahub 32 - const: nvidia,tegra186-ahub 33 34 reg: 35 maxItems: 1 36 37 clocks: 38 maxItems: 1 39 40 clock-names: 41 const: ahub 42 43 assigned-clocks: 44 maxItems: 1 45 46 assigned-clock-parents: 47 maxItems: 1 48 49 assigned-clock-rates: 50 maxItems: 1 51 52 "#address-cells": 53 const: 1 54 55 "#size-cells": 56 const: 1 57 58 ranges: true 59 60 ports: 61 $ref: /schemas/graph.yaml#/properties/ports 62 description: | 63 Contains list of ACIF (Audio CIF) port nodes for AHUB (Audio Hub). 64 These are connected to ACIF interfaces of AHUB clients.
