1Amlogic MesonX device tree bindings 2------------------------------------------- 3 4Work in progress statement: 5 6Device tree files and bindings applying to Amlogic SoCs and boards are 7considered "unstable". Any Amlogic device tree binding may change at 8any time. Be sure to use a device tree binary and a kernel image 9generated from the same source tree. 10 11Please refer to Documentation/devicetree/bindings/ABI.txt for a definition of a 12stable binding/ABI. 13 14--------------------------------------------------------------- 15 16Boards with the Amlogic Meson6 SoC shall have the following properties: 17 Required root node property: 18 compatible: "amlogic,meson6" 19 20Boards with the Amlogic Meson8 SoC shall have the following properties: 21 Required root node property: 22 compatible: "amlogic,meson8"; 23 24Boards with the Amlogic Meson8b SoC shall have the following properties: 25 Required root node property: 26 compatible: "amlogic,meson8b"; 27 28Boards with the Amlogic Meson8m2 SoC shall have the following properties: 29 Required root node property: 30 compatible: "amlogic,meson8m2"; 31 32Boards with the Amlogic Meson GXBaby SoC shall have the following properties: 33 Required root node property: 34 compatible: "amlogic,meson-gxbb"; 35 36Boards with the Amlogic Meson GXL S905X SoC shall have the following properties: 37 Required root node property: 38 compatible: "amlogic,s905x", "amlogic,meson-gxl"; 39 40Boards with the Amlogic Meson GXL S905D SoC shall have the following properties: 41 Required root node property: 42 compatible: "amlogic,s905d", "amlogic,meson-gxl"; 43 44Boards with the Amlogic Meson GXL S805X SoC shall have the following properties: 45 Required root node property: 46 compatible: "amlogic,s805x", "amlogic,meson-gxl"; 47 48Boards with the Amlogic Meson GXL S905W SoC shall have the following properties: 49 Required root node property: 50 compatible: "amlogic,s905w", "amlogic,meson-gxl"; 51 52Boards with the Amlogic Meson GXM S912 SoC shall have the following properties: 53 Required root node property: 54 compatible: "amlogic,s912", "amlogic,meson-gxm"; 55 56Boards with the Amlogic Meson AXG A113D SoC shall have the following properties: 57 Required root node property: 58 compatible: "amlogic,a113d", "amlogic,meson-axg"; 59 60Board compatible values (alphabetically, grouped by SoC): 61 62 - "geniatech,atv1200" (Meson6) 63 64 - "minix,neo-x8" (Meson8) 65 66 - "hardkernel,odroid-c1" (Meson8b) 67 - "tronfy,mxq" (Meson8b) 68 69 - "tronsmart,mxiii-plus" (Meson8m2) 70 71 - "amlogic,p200" (Meson gxbb) 72 - "amlogic,p201" (Meson gxbb) 73 - "friendlyarm,nanopi-k2" (Meson gxbb) 74 - "hardkernel,odroid-c2" (Meson gxbb) 75 - "nexbox,a95x" (Meson gxbb or Meson gxl s905x) 76 - "tronsmart,vega-s95-pro", "tronsmart,vega-s95" (Meson gxbb) 77 - "tronsmart,vega-s95-meta", "tronsmart,vega-s95" (Meson gxbb) 78 - "tronsmart,vega-s95-telos", "tronsmart,vega-s95" (Meson gxbb) 79 - "wetek,hub" (Meson gxbb) 80 - "wetek,play2" (Meson gxbb) 81 82 - "amlogic,p212" (Meson gxl s905x) 83 - "hwacom,amazetv" (Meson gxl s905x) 84 - "khadas,vim" (Meson gxl s905x) 85 - "libretech,cc" (Meson gxl s905x) 86 87 - "amlogic,p230" (Meson gxl s905d) 88 - "amlogic,p231" (Meson gxl s905d) 89 90 - "amlogic,p241" (Meson gxl s805x) 91 92 - "amlogic,p281" (Meson gxl s905w) 93 - "oranth,tx3-mini" (Meson gxl s905w) 94 95 - "amlogic,q200" (Meson gxm s912) 96 - "amlogic,q201" (Meson gxm s912) 97 - "khadas,vim2" (Meson gxm s912) 98 - "kingnovel,r-box-pro" (Meson gxm S912) 99 - "nexbox,a1" (Meson gxm s912) 100 - "tronsmart,vega-s96" (Meson gxm s912) 101 102 - "amlogic,s400" (Meson axg a113d) 103 104Amlogic Meson Firmware registers Interface 105------------------------------------------ 106 107The Meson SoCs have a register bank with status and data shared with the 108secure firmware. 109 110Required properties: 111 - compatible: For Meson GX SoCs, must be "amlogic,meson-gx-ao-secure", "syscon" 112 113Properties should indentify components of this register interface : 114 115Meson GX SoC Information 116------------------------ 117A firmware register encodes the SoC type, package and revision information on 118the Meson GX SoCs. 119If present, the following property should be added : 120 121Optional properties: 122 - amlogic,has-chip-id: If present, the interface gives the current SoC version. 123 124Example 125------- 126 127ao-secure@140 { 128 compatible = "amlogic,meson-gx-ao-secure", "syscon"; 129 reg = <0x0 0x140 0x0 0x140>; 130 amlogic,has-chip-id; 131}; 132
