[PATCH V3 7/7] mmc: sdhci-pci: enable runtime PM for Medfield SDIO

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

 



Runtime PM for SDIO is no longer enabled by default
(see 5c7f0e083d2d98ba14ddd10e88f001a0ead4cae4) so
it must now be enabled per platform, in this case
Medfield uses it.
