From 2c31d9498cb85dcf37806237870e8ccf4dbf84e0 Mon Sep 17 00:00:00 2001 From: Doug Anderson Date: Tue, 12 Aug 2014 16:21:14 -0700 Subject: [PATCH] ARM: dts: Enable emmc and sdmmc on the rk3288-evb boards This enables basic SD and eMMC support. Things are not yet running at the fastest speed and we don't have the regulators specified, but we can at least use the eMMC and SD cards now. A note: * Though MMC DDR50 mode is partially supported in the dw_mmc rk3288-specific code in Addy's patch, Addy's patch doesn't add tuning support. That means DDR50 mode is not reliable. From the 3288 TRM: "Tuning is required for other speed modes-such as DDR50-even though the output delay from the card is less than one cycle." Thus, we don't enable MMC DDR50 mode in this patch.
