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"

	- For i.MX8MN SoCs should be "fsl,imx8mn-src", "fsl,imx8mq-src", "syscon"

	- For i.MX8MP SoCs should be "fsl,imx8mp-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 and

<dt-bindings/reset/imx8mq-reset.h> for i.MX8MN and

<dt-bindings/reset/imx8mp-reset.h> for i.MX8MP
