Subject: [PATCH] mmc: sdhci: check the quirk HISPD_BIT for SD3.0 card
Date: Thu, 15 Nov 2012 17:15:31 +0900	[thread overview]
Message-ID: <50A4A4A3.90903@samsung.com> (raw)

If SD-card is more than SD3.0 card, set to ctrl with UHS-I modes.
But in case of Samsung-SoC, didn't use the SDHCI_CTRL_HISPD.
So need to check the quirk for SDHCI_QUIRK_NO_HISPD_BIT.
