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"
|
|
- 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 indicies see
|
|
<dt-bindings/reset/imx7-reset.h> for i.MX7 and
|
|
<dt-bindings/reset/imx8mq-reset.h> for i.MX8MQ
