From 4db25fe7fa0e68196cf3a89dae7f9632aecb3abd Mon Sep 17 00:00:00 2001 From: Jean-Jacques Hiblot Date: Tue, 30 Jan 2018 16:01:50 +0100 Subject: [PATCH] dts: am57xx-beagle-x15: disable UHS and HS200 support The UHS modes are not supported in beagle-x15 because it's not possible to switch the IO lines supply voltage to 1.8v. Also HS200 cannot be supported on mmc2, because the IO lines of mmc2 are connected to 3.3v.
