|
|
|
|
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.
|
|
|
|
|
|
|
|
|
|
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, i.MX8MM and i.MX8MN,
|
|
|
|
|
<dt-bindings/reset/imx8mp-reset.h> for i.MX8MP.

dt-bindings: reset: fsl,imx7-src: Add i.MX 8M compatibles
DTSes with new i.MX 8M SoCs introduce their own compatibles so add them
to fix dtbs_check warnings like:
arch/arm64/boot/dts/freescale/imx8mm-evk.dt.yaml: reset-controller@30390000:
compatible:0: 'fsl,imx8mm-src' is not one of ['fsl,imx7d-src', 'fsl,imx8mq-src', 'fsl,imx8mp-src']
From schema: Documentation/devicetree/bindings/reset/fsl,imx7-src.yaml
arch/arm64/boot/dts/freescale/imx8mm-evk.dt.yaml: reset-controller@30390000:
compatible:1: 'syscon' was expected
arch/arm64/boot/dts/freescale/imx8mm-evk.dt.yaml: reset-controller@30390000:
compatible: ['fsl,imx8mm-src', 'fsl,imx8mq-src', 'syscon'] is too long
