Those device 15 nodes should specify the reset line on the SRC in their resets 16 property, containing a phandle to the SRC device node and a 17 RESET_INDEX specifying which module to reset, as described in 18 reset.txt 19 20 The following RESET_INDEX values are valid for i.MX5: 21 GPU_RESET 0 22 VPU_RESET 1 23 IPU1_RESET 2 24 OPEN_VG_RESET 3 25 The following additional RESET_INDEX value is valid for i.MX6: 26 IPU2_RESET 4 27 28properties: 29 compatible: 30 oneOf: 31 - const: "fsl,imx51-src" 32 - items: 33 - const: "fsl,imx50-src" 34 - const: "fsl,imx51-src" 35 - items: 36 - const: "fsl,imx53-src" 37 - const: "fsl,imx51-src" 38 - items: 39 - const: "fsl,imx6q-src" 40 - const: "fsl,imx51-src" 41 - items: 42 - const: "fsl,imx6sx-src" 43 - const: "fsl,imx51-src" 44 - items: 45 - const: "fsl,imx6sl-src" 46 - const: "fsl,imx51-src" 47 - items: 48 - const: "fsl,imx6ul-src" 49 - const: "fsl,imx51-src" 50 - items: 51 - const: "fsl,imx6sll-src" 52 - const: "fsl,imx51-src" 53 54 reg: 55 maxItems: 1 56 57 interrupts: 58 items: 59 - description: SRC interrupt 60 - description: CPU WDOG interrupts out of SRC 61 minItems: 1 62 63 '#reset-cells': 64 const: 1 65 66required: 67 - compatible 68 - reg 69 - interrupts 70 - '#reset-cells' 71 72additionalProperties: false 73 74examples: 75 - | 76 reset-controller@73fd0000 { 77 compatible = "fsl,imx51-src"; 78 reg = <0x73fd0000 0x4000>; 79 interrupts = <75>; 80 #reset-cells = <1>; 81 }; 82
