Your commit msg should also explain anything unusual here, like above. Best regards, Krzysztof

When the vendor literally says "C-SKY", it's hard to buy why csky shouldn't be used here. Xuantie is described as being a brand, where at least t-head was a company. This seems akin to having "snapdragon,msm8660" instead of "qcom,msm8660", for example. > > Your commit msg should also explain anything unusual here, like above. > > Best regards, > Krzysztof >

We could leave the one C-SKY vendor entry, how about:

"XuanTie is a brand", so not suitable for vendor prefixes. https://www.xrvm.com/declaration What's more: <<A reference to “C-SKY”, “we” or “us” is a reference to C-SKY Microsystems Co., Ltd. of Room >> So again c-sky.
