Each pipeline can be composed of up to four 16 layers. It is typically connected to a digital display connector like HDMI. 17 18properties: 19 compatible: 20 oneOf: 21 - items: 22 - const: arm,mali-d32 23 - const: arm,mali-d71 24 - const: arm,mali-d71 25 26 reg: 27 maxItems: 1 28 29 interrupts: 30 maxItems: 1 31 32 clock-names: 33 const: aclk 34 35 clocks: 36 maxItems: 1 37 description: The main DPU processor clock 38 39 "#address-cells": 40 const: 1 41 42 "#size-cells": 43 const: 0 44 45 memory-region: 46 maxItems: 1 47 description: 48 Phandle to a node describing memory to be used for the framebuffer. 49 If not present, the framebuffer may be located anywhere in memory. 50 51 iommus: 52 description: 53 The stream IDs for each of the used pipelines, each four IDs for the 54 four layers, plus one for the write-back stream. 55 minItems: 5 56 maxItems: 10 57 58patternProperties: 59 '^pipeline@[01]$': 60 type: object 61 description: 62 clocks 63 64 properties: 65 reg: 66 enum: [ 0, 1 ] 67 68 clock-names: 69 const: pxclk 70 71 clocks: 72 maxItems: 1 73 description: The input reference for the pixel clock. 74 75 port: 76 $ref: /schemas/graph.yaml#/$defs/port-base 77 unevaluatedProperties: false 78 79additionalProperties: false 80 81required: 82 - "#address-cells" 83 - "#size-cells" 84 - compatible 85 - reg 86 - interrupts 87 - clock-names 88 - clocks 89 - pipeline@0 90 91examples: 92 - | 93 display@c00000 { 94 #address-cells = <1>; 95 #size-cells = <0>; 96 compatible = "arm,mali-d71"; 97 reg = <0xc00000 0x20000>; 98 interrupts = <168>; 99 clocks = <&dpu_aclk>; 100 clock-names = "aclk"; 101 iommus = <&smmu 0>, <&smmu 1>, <&smmu 2>, <&smmu 3>, 102 <&smmu 8>, 103 <&smmu 4>, <&smmu 5>, <&smmu 6>, <&smmu 7>, 104 <&smmu 9>; 105 106 dp0_pipe0: pipeline@0 { 107 clocks = <&fpgaosc2>; 108 clock-names = "pxclk"; 109 reg = <0>; 110 111 port { 112 dp0_pipe0_out: endpoint { 113 remote-endpoint = <&db_dvi0_in>; 114 }; 115 }; 116 }; 117 118 dp0_pipe1: pipeline@1 { 119 clocks = <&fpgaosc2>; 120 clock-names = "pxclk"; 121 reg = <1>; 122 123 port { 124 dp0_pipe1_out: endpoint { 125 remote-endpoint = <&db_dvi1_in>; 126 }; 127 }; 128 }; 129 }; 130...
