We (along with Xi Ruoyao and Runhua He) tested this patchset against 
v6.18-rc1 on the following platforms featuring YT6801:

- Loongson XA61201 (LoongArch, Loongson 3A6000-HV)
- Loongson AC612A0_V1.1 (LoongArch, Loongson 3C6000/S)
- Loongson XB612B0_V1.1 (LoongArch, Loongson 3B6000)
- MECHREVO WUJIE14-GX4HRXL (x86-64)

With performance within expectation and S3/reboot working. Both ports 
work on those with two interfaces (AC612A0_V1.1 and XB612B0_V1.1). LED 
indicators do not seem to work properly at this moment, but this was 
already described in your original email.

With that:
