[PATCH/RFC] tmio_mmc: keep card-detect interrupts enabled

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



On SuperH platforms the SDHI controller does not produce any command IRQs 
after a completed IO. This leads to card-detect interrupts staying 
disabled. Do not disable card-detect interrupts on DATA IRQs.

Marked as RFC because I'm not really sure this is a correct approach to 
fix this problem, and whether this will have negative effect on other 
tmio_mmc MFD users.
