You need to define what each one is as a schema. How does the driver know which one is the vring region for example? Minimally, it's: items: - description: ... - description: ... - description: ... But if what's present is variable, then it gets more complicated. If the OS side doesn't need to know what each region is, then you can do just: minItems: N maxItems: M Rob > + > +required: > + - compatible > + - clocks > + - syscon > + > +additionalProperties: false > + > +examples: > + - | > + #include <dt-bindings/clock/imx7d-clock.h> > + m4_reserved_sysmem1: cm4@80000000 { > + reg = <0x80000000 0x80000>; > + }; > + > + m4_reserved_sysmem2: cm4@81000000 { > + reg = <0x81000000 0x80000>; > + }; > + > + imx7d-cm4 { > + compatible = "fsl,imx7d-cm4"; > + memory-region = <&m4_reserved_sysmem1>, <&m4_reserved_sysmem2>; > + syscon = <&src>; > + clocks = <&clks IMX7D_ARM_M4_ROOT_CLK>; > + }; > + > +... > diff --git a/Documentation/devicetree/bindings/remoteproc/imx-rproc.txt b/Documentation/devicetree/bindings/remoteproc/imx-rproc.txt > deleted file mode 100644 > index fbcefd965dc4..000000000000 > --- a/Documentation/devicetree/bindings/remoteproc/imx-rproc.txt > +++ /dev/null > @@ -1,33 +0,0 @@ > -NXP iMX6SX/iMX7D Co-Processor Bindings > ----------------------------------------- > - > -This binding provides support for ARM Cortex M4 Co-processor found on some > -NXP iMX SoCs. > - > -Required properties: > -- compatible Should be one of: > - "fsl,imx7d-cm4" > - "fsl,imx6sx-cm4" > -- clocks Clock for co-processor (See: ../clock/clock-bindings.txt) > -- syscon Phandle to syscon block which provide access to > - System Reset Controller > - > -Optional properties: > -- memory-region list of phandels to the reserved memory regions. > - (See: ../reserved-memory/reserved-memory.txt) > - > -Example: > - m4_reserved_sysmem1: cm4@80000000 { > - reg = <0x80000000 0x80000>; > - }; > - > - m4_reserved_sysmem2: cm4@81000000 { > - reg = <0x81000000 0x80000>; > - }; > - > - imx7d-cm4 { > - compatible = "fsl,imx7d-cm4"; > - memory-region = <&m4_reserved_sysmem1>, <&m4_reserved_sysmem2>; > - syscon = <&src>; > - clocks = <&clks IMX7D_ARM_M4_ROOT_CLK>; > - }; > -- > 2.30.0 >
