I don't focus on the upstream for a while, was this problem still here
recently? Could you attach the base commit, so I can reproduce it.
About one months ago, gaokun3 worked well with Linux 7.0.0. I enabled
i2c4(gpi_dma0, seid=4), spi6(gpi_dma0, seid=6), i2c15(gpi_dma1, seid=7)

I thought this commit should have fixed the issue in [1]
