1Freescale i.MX7 System Reset Controller 2====================================== 3 4Please also refer to reset.txt in this directory for common reset 5controller binding usage. 6 7Required properties: 8- compatible: Should be "fsl,imx7-src", "syscon" 9- reg: should be register base and length as documented in the 10 datasheet 11- interrupts: Should contain SRC interrupt 12- #reset-cells: 1, see below 13 14example: 15 16src: reset-controller@30390000 { 17 compatible = "fsl,imx7d-src", "syscon"; 18 reg = <0x30390000 0x2000>; 19 interrupts = <GIC_SPI 89 IRQ_TYPE_LEVEL_HIGH>; 20 #reset-cells = <1>; 21}; 22 23 24Specifying reset lines connected to IP modules 25============================================== 26 27The system reset controller can be used to reset various set of 28peripherals. Device nodes that need access to reset lines should 29specify them as a reset phandle in their corresponding node as 30specified in reset.txt. 31 32Example: 33 34 pcie: pcie@33800000 { 35 36 ... 37 38 resets = <&src IMX7_RESET_PCIEPHY>, 39 <&src IMX7_RESET_PCIE_CTRL_APPS_EN>; 40 reset-names = "pciephy", "apps"; 41 42 ... 43 }; 44 45 46For list of all valid reset indicies see 47<dt-bindings/reset/imx7-reset.h> 48
