Tested for TIMING_CLOCK_RATE would have been 255 instead of 0. Handle case we should propagate the error. Commit a91fe279ae75 (mmc: mxs: use standard flag for 2012 6:23 PMI use i.MX280 with SDIO-connectd WiFi module on our own product (silex SX-570).

This also adds support for mxs-saif driver to the new header file. for next.

Rename it to mxs-dma.h, and create a new platform data in the driver. Convert current users to use value to determine if a card is present. Dear Shawn Guo, > Copy Chris who should be able to
