[PATCH 36/41] ARM: dts: am57xx-idk: Set MMC2 IO voltage to 3.3V
From: Kishon Vijay Abraham I
Date: Fri May 19 2017 - 04:20:49 EST
From: Sekhar Nori <nsekhar@xxxxxx>
MMC2 interface on AM57xx IDK, connected to
onboard eMMC, has IO voltage fixed to 3.3V.
Add no-1-8-v device-tree property to mmc2 node
in the board's device-tree file to reflect
this.
Note that the AM57xx SoC itself supports
dual-voltage on MMC2. The limitation above is
due to the board.
