From 5b434d7e9ebd5664dd2a649d08f0ab8d1c8a1f71 Mon Sep 17 00:00:00 2001 From: Nishanth Menon Date: Tue, 21 Oct 2014 09:35:56 -0500 Subject: [PATCH] ARM: dts: dra72-evm: Add MMC nodes Add MMC1 and 2 nodes. MMC1 is SDcard and MMC2 is eMMC. NOTE on MMC1 card detect: Ideally, we should be using in-built SDCD support, but we dont have it yet. So, use the fact that control module of DRA7 is setup such that no matter what mode one configures it, GPIO option is always hardwired in - use GPIO mode for SDcard detection. [peter.ujfalusi@ti.com] The power line feeding the SD card is also used by other devices on the EVM. Use generic name instead of mmc2_3v3 so when other devices want to use the same regulator it will look a bit better.
