Freescale i.MX7 System Reset Controller ====================================== Please also refer to reset.txt in this directory for common reset controller binding usage. Required properties: - compatible: - For i.MX7 SoCs should be "fsl,imx7d-src", "syscon" - For i.MX8MQ SoCs should be "fsl,imx8mq-src", "syscon" - For i.MX8MM SoCs should be "fsl,imx8mm-src", "fsl,imx8mq-src", "syscon" - reg: should be register base and length as documented in the datasheet - interrupts: Should contain SRC interrupt - #reset-cells: 1, see below example: src: reset-controller@30390000 { compatible = "fsl,imx7d-src", "syscon"; reg = <0x30390000 0x2000>; interrupts = <GIC_SPI 89 IRQ_TYPE_LEVEL_HIGH>; #reset-cells = <1>; }; Specifying reset lines connected to IP modules ============================================== The system reset controller can be used to reset various set of peripherals. Device nodes that need access to reset lines should specify them as a reset phandle in their corresponding node as specified in reset.txt. Example: pcie: pcie@33800000 { ... resets = <&src IMX7_RESET_PCIEPHY>, <&src IMX7_RESET_PCIE_CTRL_APPS_EN>; reset-names = "pciephy", "apps"; ... }; For list of all valid reset indices see <dt-bindings/reset/imx7-reset.h> for i.MX7, <dt-bindings/reset/imx8mq-reset.h> for i.MX8MQ and <dt-bindings/reset/imx8mq-reset.h> for i.MX8MM |
