[PATCH v1 1/1]sdhci-pxa: init_sdh for different platform

Different platform will provide different init_sdh to handle private register is not same in various platform. Put init_sdh in set_clock is we don't want to add more call back function to sdhci.c to keep sdhci.c as simple as possible. Currently init_sdh will be called several times when clk is chan

mmc: Huge delay is seen when SD card is removed while transferring large media file

Hi, Scenario: After SD card is inserted and partitions are mounted, start transferring a large media file (for ex: 200MB) to SD. Remove the card in between. Problem: There is a huge delay of ~20secs when the user get notified about the card removal. This delay depends on the size of the file to b
