I'm also very interested to know why we can't just use "snps,dw-abp-ssi", maybe I missed some discussion ... I googled examples of soc-specific defined in the code, and it doesn't seem to be much, only arch/mips/boot/dts/mscc/ocelot.dtsi and arch/riscv/boot/dts/thead/th1520.dtsi. Specially, I looked at the commits for th1520 and saw this https://lore.kernel.org/linux-riscv/20240703-garbage-explicit-bd95f8deb716@wendy/. It tells if the fallback works identically, then the specific compatible is not needed.+ + spi0: spi@7040004000 { + compatible = "snps,dw-apb-ssi";I thought were were dropping the use of "snps,dw-abp-ssi" in isolation, and starting to require soc-specific compatibles now. Rob, Krzysztof?
This makes me more confused :) Regards, Chen
