All CPU accesses to 12 the APE subsystem go through the ACONNECT via an APB to AXI wrapper. All 13 devices accessed via the ACONNNECT are described by child-nodes. 14 15maintainers: 16 - Jon Hunter <jonathanh@nvidia.com> 17 18properties: 19 compatible: 20 oneOf: 21 - const: nvidia,tegra210-aconnect 22 - items: 23 - enum: 24 - nvidia,tegra234-aconnect 25 - nvidia,tegra186-aconnect 26 - nvidia,tegra194-aconnect 27 - const: nvidia,tegra210-aconnect 28 29 clocks: 30 items: 31 - description: Must contain the entry for APE clock 32 - description: Must contain the entry for APE interface clock 33 34 clock-names: 35 items: 36 - const: ape 37 - const: apb2ape 38 39 power-domains: 40 maxItems: 1 41 42 "#address-cells": 43 const: 1 44 45 "#size-cells": 46 const: 1 47 48 ranges: true 49 50patternProperties: 51 "@[0-9a-f]+$": 52 type: object 53 54required: 55 - compatible 56 - clocks 57 - clock-names 58 - power-domains 59 - "#address-cells" 60 - "#size-cells" 61 - ranges 62 63additionalProperties: false 64 65examples: 66 - | 67 #include<dt-bindings/clock/tegra210-car.h> 68 69 aconnect@702c0000 { 70 compatible = "nvidia,tegra210-aconnect"; 71 clocks = <&tegra_car TEGRA210_CLK_APE>, 72 <&tegra_car TEGRA210_CLK_APB2APE>; 73 clock-names = "ape", "apb2ape"; 74 power-domains = <&pd_audio>; 75 76 #address-cells = <1>; 77 #size-cells = <1>; 78 ranges = <0x702c0000 0x702c0000 0x00040000>; 79 80 // Child device nodes follow ... 81 }; 82 83...
