From 214fc309d1387e822d606a33a10e31cacfe83520 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Thu, 8 Aug 2013 12:38:31 +0200 Subject: mmc: slot-gpio: Add debouncing capability to mmc_gpio_request_cd() Add a debounce parameter to the mmc_gpio_request_cd() function that enables GPIO debouncing when set to a non-zero value. This can be used by MMC host drivers to enable debouncing on the card detect signal.
