From 3853a042325e8f497c199020979c4fc824528c6e Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Fri, 6 Feb 2015 14:12:56 +0200 Subject: mmc: core: Record card drive strength In preparation for adding drive strength support for eMMC, add drive_strength to struct mmc_card to record the card drive strength for UHS-I modes and HS200 / HS400. For eMMC this will be needed when switching between HS200 and HS400.
