| Freescale i.MX7 System Reset Controller |
| ====================================== |
| |
| Please also refer to reset.txt in this directory for common reset |
| controller binding usage. |
| |
| Required properties: |
| - compatible: Should be "fsl,imx7-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"; |
| |
| ... |
| }; |
| |
