From f3c55a7b5d7f2d40c805a62174bb733b55875523 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Tue, 7 Feb 2012 14:48:55 +0200 Subject: [PATCH] mmc: sdhci-pci: add SDHCI_QUIRK2_HOST_OFF_CARD_ON for Medfield SDIO SDIO is powered separately from the host controller, so the card can remain on while the host controller is powered off during suspend.
