From 19206b174222f0ffef025fe53c9fbd4ab536fcfb Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Fri, 23 Jul 2010 09:27:18 +0900 Subject: ARM: SAMSUNG: Add new s3c-sdhci card detection methods for Samsung SoCs On some Samsung SoCs not all SDHCI controllers have card detect (CD) line. For some embedded designs it is not even needed, because ususally the device (like SDIO flash memory or wifi controller) is permanently wired to the controller. There are also systems which have a card detect line connected to some of the external interrupt lines or the presence of the card depends on some other actions (like enabling a power regulator). This patch adds all required changes to platform support code, so another patch, which extends the driver with support for the new card detection methods can be applied.
