Ian Lepore bba987dc50 Add a new SDHCI quirk, SDHCI_QUIRK_DONT_SET_HISPD_BIT. Apparently some ... sdhci controllers, such as the one on a Raspberry Pi, mishandle the signal timing in high speed signaling mode, but run just fine in standard mode with the bus running at frequencies between 25-50MHz (which shouldn't work). This is the solution adopted by U-Boot and other OSes (linux and *BSD) for the timeouts on Raspberry Pi boards with certain SD cards. Some research shows that this quirk is also used on a few other boards, so the fix is a generic quirk instead of being in the RPi-specific driver code. This change is based on information discovered by Michal Meloun.		2015-01-17 19:57:03 +00:00
