Filename matching the compatible.
loongson,ls-spi.yaml is for ls2k-spi and ls7a-spi, I will add following
desription:


properties:
    compatible:
      enum:
        - loongson,ls2k-spi
        - loongson,ls7a-spi
OK then.

I was to explain why that yaml was name as "loongson,ls-spi.yaml"  rather than "loongson,ls2k-spi.yaml"

because that need consider about  yaml filename to match "loongson,ls2k-spi" and "loongson,ls7a-spi".

Drop the quotes. What was the base of your code here?
okay, I will drop the quotes.    and I don't got it  about the code base
that you said.

you meaning is advice me add a line  as follows ?
I meant, from which other file did you copy it?
okay,  but I maybe forgot it,  I should be refer other spi yaml file.

+
+  clock-names:
+    const: boot
Drop clock-names, not needed for single entry.
if drop the clock-names entry, the yaml file will compile fail.
Obviously you have to also drop it from DTS and driver...

drop clock-names should be not  affect my driver,  but I notice other lots of arm64 platform dts

was keep clock-names and clock in dts when use grep search "clock-names".

[zhuyinbo@localhost www.kernel.org]$ grep -rns "clock-names" arch/arm64/

arch/arm64/boot/dts/sprd/sc9863a.dtsi:280:            clock-names = "apb_pclk"; arch/arm64/boot/dts/sprd/sc9863a.dtsi:305:            clock-names = "apb_pclk"; arch/arm64/boot/dts/sprd/sc9863a.dtsi:330:            clock-names = "apb_pclk"; arch/arm64/boot/dts/sprd/sc9863a.dtsi:367:            clock-names = "apb_pclk";
