From b097e07f57930eda774c83aa46e8e401686d01dc Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Fri, 6 Feb 2015 14:12:57 +0200 Subject: mmc: mmc: Read card's valid driver strength mask In preparation for supporing drive strength selection for eMMC, read the card's valid driver strengths. Note that though the SD spec uses the term "drive strength", the JEDEC eMMC spec uses the term "driver strength".
