Subject[Patch 0/1] mmc: Added quirks for Ricoh 1180:e823 lower base clock frequency
Date

Ricoh 1180:e823 does not recognize certain types of SD/MMC cards.
- Buffalo SD 512MB
dmesg: I/O error, dev mmcblk0, sector xxx
- Kingston SD 2GB
dmesg: I/O error, dev mmcblk0, sector xxx
- Patriot Micro SDHC
dmesg: I/O error, dev mmcblk0, sector xxx.

Lowering the SD base clock frequency from 200Mhz to 50Mhz fixes
this issue. This solution was suggest by Koji Matsumuro, Ricoh
Company,Ltd. The patch was tested on Toshiba Tecra R850 by Daniel
Manrique.
