Because twl4030 now has its own device files, move and rename twl4030_mmc_config. twl4030_mmc_config initializes the twl4030 power setting to the mmc device. Because it is in the twl4030 power domain, move it out of drivers/mmc/omap3_mmc.c and into drivers/power/twl4030.c. The function was renamed to twl4030_power_mmc_init because all the functions in this file are to have the format twl4030_power_<device>_<action> In this case the suffix is mmc_init so device : mmc action : init Signed-off-by: Tom Rix <Tom.Rix@windriver.com> Acked-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Acked-by: Heiko Schocher <hs@denx.de>
