From: Adrian Hunter Date: Mon, 3 Oct 2011 12:33:34 +0000 (+0300) Subject: mmc: sdhci-pci: add runtime pm support X-Git-Tag: v3.2-rc1~129^2~19 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=66fd8ad5100b5003046aa744a4f12fa31bb831f9;p=pandora-kernel.git mmc: sdhci-pci: add runtime pm support Ths patch allows runtime PM for sdhci-pci, runtime suspending after inactivity of 50ms and ensuring runtime resume before SDHC registers are accessed. During runtime suspend, interrupts are masked. The host controller state is restored at runtime resume. For Medfield, the host controller's card detect mechanism is supplanted by an always-on GPIO which provides for card detect wake-up.
