From: kishon@ti.com (Kishon Vijay Abraham I) Date: Fri, 19 May 2017 13:45:36 +0530 Subject: [PATCH 36/41] ARM: dts: am57xx-idk: Set MMC2 IO voltage to 3.3V In-Reply-To: <20170519081541.26753-1-kishon@ti.com> References: <20170519081541.26753-1-kishon@ti.com> Message-ID: <20170519081541.26753-37-kishon@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Sekhar Nori 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.
