Subject: [PATCH] mmc: sdhci-of-at91: fix card detect when using runtime PM
Date: Thu, 11 Feb 2016 14:48:57 +0100	[thread overview]
Message-ID: <1455198537-21791-1-git-send-email-ludovic.desroches@atmel.com> (raw)

Add quirk broken card detection to enable card detection polling. It is
a short term solution until reworking PM stuff.

If the card detect signal is connected to the sdhci controller and not a
gpio, when runtime PM suspend happens, we have no way to wake up on a card
detect event since these irqs are no more enabled.
