From 451c89578eb4791b9d329eb71a79e6715e60f89e Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Tue, 4 Dec 2012 16:51:36 +0100 Subject: mmc: extend the slot-gpio card-detection to use host's .card_event() method The slot-gpio API provides a generic card-detection handler. To support a wider range of hosts it has to call the host's card-event callback, if implemented. Also increase the debounce interval to 200ms to match the SDHCI driver.
