add power-domains and power-domain-names property

Why? Please write complete sentences explaining why you are doing this.

Sorry, I did not describe in detail.

The Sky1 PCIe controller sits in a power domain that must be enabled before

the controller can be accessed.

Describe the power-domains property so that DTS files can reference the

correct power domain provider.

There is no such syntax. Open any existing bindinh.

Sorry, They come from
Documentation/devicetree/bindings/pci/fsl,imx6q-pcie-common.yaml

There is no such syntax there.

Just open the file.

Maybe we see it from the different views. Anyway, it's not important.
Do you agree this scheme? Like this:
  power-domains:
    maxItems: 1
  power-domain-names:
    maxItems: 1

Execute the two commands below before submit patch every time.

make O=$OUTKNL dt_binding_check
make O=$OUTKNL dt_binding_check
DT_SCHEMA_FILES=cix,sky1-pcie-host.yaml

we don't find any warning or error. So we think all is ok.

No, because there is no such code nowhere. Please take other bindings as an
example. You miss here maxItems.

Ok, thanks for your kindly remind. We get it.
Thanks for your suggestions

Best regards
Gary
