Date: Fri, 5 Aug 2011 12:35:03 +0900 From: Seungwon Jeon <tgih.jun@...sung.com> To: linux-mmc@...r.kernel.org, cjb@...top.org Cc: linux-kernel@...r.kernel.org, Seungwon Jeon <tgih.jun@...sung.com> Subject: [PATCH] mmc: dw_mmc: Fix DDR mode support. Host driver can't get a hint of DDR mode through ios->ddr flag anymore. ios->timing is currently used to inform DDR mode as a substitute. And capability of MMC_CAP_MMC_HIGHSPEED is added for DDR support.
