[PATCH 1/7] sdhci: Rework some of the quirk behaviour

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

 



As the quirks go ever more complex it's getting harder and harder to integrate
new drivers. The Intel MID devices add a whole further collection of new
quirks so instead of quirks start moving some stuff to overridable functions.

We also introduce an sdhci_reset_all helper which is told if the reset is
being done during init (which needs to be avoided by some hw) or on exit
in which case it doesn't.

Arguably the driver wants to be lots of drivers and "libsdhci" but that would
be a massive undertaking.
