Hi Balaji, in commit 9d1fd9e7b19d66a35ee4e760b30a3b9a168c20a2, you introduced a major change in s3cmci.c: you make it explicitly use the SD_3V3 regulator and give this precedence over the platform set_power callback.
Unfortunately, there are a number of problems with this: - s3cmci.c shouldn't have to know about a platform's power arrangements. That's why we have set_power. - In GTA02, SD_3V3 is actually used for the MMC interface of the Glamo, so s3cmci.c is (unsuccessfully) trying to grab somebody else's regulator. - If the whole thing worked, it would take precedence over the callback to gta02_s3c_mmc_set_power, thus disabling the WLAN reset logic. Fortunately, all this does nothing on GTA02 because the regulator is tied to gta02_mmc_dev so regulator_get returns NULL and s3cmci.c returns to its normal behaviour after a bit of grumbling. I'd suggest to revert the regulator changes you made to s3cmci.h and s3cmci.c, introduce a gta01_s3c_mmc_set_power function for GTA01 in arch/arm/mach-s3c2410/mach-gta01.c, and handle the regulator access there. - Werner
