From: Linus Walleij <linus.walleij@xxxxxxxxxx> This is a collection of ST-Ericsson patches for MMCI for 3.1. They are arranged in rising controversy-order for incremental handling... [1/4] is pretty straight-formward handling of a missing error bit. [2/4] adjusts the min frequency for the card in accordance with needs we have on the ST Micro based platforms. [3/4] is a reqrite of the earlier discussed patch that synchronize DMA termination callbacks with the DATAEND IRQ, but now we have added a timeout so that failed transactions can be handled. [4/4] rewrites the pio_write function to work properly with non-4-byte aligned accesses, and replaces an earlier workaround. For regular MMC/SD accesses which are always evenly divisible by 4 it should have no effect, the difference is in the handling of odd transactions, such as can be seen when processing SDIO requests. All patches have been tested on U8500, U300 and RealView PB1176 with mounted filesystems exercising read and write, so as to assure there are no obvious regressions.
