2012-01-13mmc: sdio: support SDIO UHS cardsPavan Kunapuli
This patch adds support for sdio UHS cards per the version 3.0 spec. UHS mode is only enabled for version 3.0 cards when both the host and the controller support UHS modes. 1.8v signaling support is removed if both the card and the host do not support UHS. This is done to maintain compatibility and some system/card combinations break when 1.8v signaling is enabled when the host does not support UHS.

When commands timeout, previously we had code to retry the same command 3 times. But under some situations 3 retries do not suffice. Increasing the retries to 10 does the trick. Also if the card does not respond after 10 retries then the card is dead for sure. But if the same card responds in between 3 to 10 retries then it is always beneficial to have retries as 10.

This does not work as do_dma is used to see whether dma can be used for the current transfer. Instead, we have to set host->dma to NULL.
