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";
