[PATCH] mci: collect host operation in struct mci_ops

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

 



The number of ops implementable by MCI drivers increase due to HS200
support and will increase more for HS400. Collecting them into a common
struct makes it easier to specialize them for drivers that support
multiple variants and makes code more similar to Linux.

No functional change.
