Hi Lee Jones:
I send this email mainly for the fllowing two things;
1.Is there anything unclear about the patch "mfd:rtsx: do retry when
dma transfer error"
2.Whether the pach I submitted in email "[PATCH v4] mfd:rtsx: do
retry when DMA transfer error"
will be merged?

When DMA transfer error with -EILSEQ, the request will retry some times,
but when with errno -EINVAL, the request will be aborted directly.
At the same time the DMA transfer error truely beacuse of the Illegal
byte sequence,
so -EILSEQ

The UHS_SER104_MAX_DTR which is in "card_clock = UHS_SER104_MAX_DTR
- (pcr->dma_error_count *2000)" is defined in linux/mmc/card.h, so

HI lee.jones
I submitted my patch a few months ago, but the patch was not merged.
I want to know what causes this, so that I can update the patch and make
the patch merged.

the request should be reissued when dma transfer error.
for rts5227, the clock freq need to step reduce when error occurred.
