[PATCH] mmc: Test bus-width for old MMC devices (v2)

From: Aries Lee Some old MMC devices fail with the 4/8 bits the driver tries to use exclusively. This patch adds a test for the given bus setup and falls back to the lower bit mode (until 1-bit mode) when the test fails. [Major rework and refactoring by tiwai] [Quirk addition and many fixes by

[PATCH 0/4] Add SDHCI driver for Tegra

Hi Chris, This series introduces a SDHCI driver for the on-chip MMC/SDIO controller on tegra. Some of the erratas weren't feasible to work around locally in the driver, so it also adds a couple of new quirk bits. Thanks, -Olof -- To unsubscribe from this list: send the line "unsubscribe linux-m

Hi Arnd, Thanks a lot for your help so far. I've found a bit of time to test stuff now. On Wed, Dec 8, 2010 at 12:08 AM, Arnd Hannemann wrote: > Am 07.12.2010 09:37, schrieb Magnus Damm: >> On Tue, Dec 7, 2010 at 9:22 PM, Arnd Hannemann wrote: >>> Am 07.12.2010 00:39, schrieb Magnus Damm:

RE: [PATCH v5 0/4]implement eMMC4.4 standard HW reset feature

Hi all, This feature can reset eMMC card when card cannot response any command. As eMMC4.4 standard recommended, the HW reset will only be launched when card occurs timeout errors. To make sure card can be reset, using HW reset instead of using command 0. So if this kind of scenario occurs, these
