So this patch was adding Loongson1 dmaengine driver which is a platform
device. I asked about the platform device and was told that [1] creates
the platform device. I am not sure if that is the recommended way given
that you have been asking people to not use platform devices.

[1]: https://patchwork.kernel.org/patch/12281691

So is [1] the correct approach or should this be fixed?
