-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
