From 67d0d04a762db4bd610fd628ad683b5d7dc905e7 Mon Sep 17 00:00:00 2001 From: Vincent Yang Date: Tue, 20 Jan 2015 16:05:16 +0800 Subject: mmc: sdhci: add a quirk for tuning work around This patch defines a quirk for tuning work around for some sdhci host controller. It sets both SDHCI_CTRL_EXEC_TUNING and SDHCI_CTRL_TUNED_CLK for tuning. It is a preparation and will be used by Fujitsu SDHCI controller f_sdh30 driver.
