From e1ea7c44d67dde263c13e1aef300cab408236994 Mon Sep 17 00:00:00 2001 From: Jaehoon Chung Date: Tue, 26 Jul 2016 19:03:49 +0900 Subject: [PATCH] mmc: sdhci: revert "mmc: sdhci: Claer high speed if not supported" This "commit 429790026021d522d51617217d4b86218cca5750" is wrong. SDHCI_QUIRK_NO_HISPD_BIT is for skipping to set CTRL_HISPD bit. For example, Exynos didn't have CTRL_HISPD. But Highspeed mode is supported. (This quirks doesn't mean that driver didn't support the Highseepd mode.) Note: If driver didn't support the Highspeed Mode, use or add the other quirks. After applied this patch, all Exynos SoCs are just running with 25MHz.
