Though roughly, we re-created 3 files codec driver, platform drive and 
machine driver. (Not debugged/tested)
Could you check these files ?

(1)codec driver
    ml26124.c ml26124.h

(2)platform driver
    ml7213ioh-plat.c ml7213ioh-plat.h ioh_i2s_config.h ioh_i2s.h

(3)machine driver
    ml7213ioh-machine.c

Thanks in advance.
