As I know there are the driver strength function. please use it.
Related with VA_GPIOx I will comment it at different patch.

Related with HSMMC, Anndrew and Ben want to know which functionality
support exactly at s5p series.
E.g., Why SDCLK is required. you can find these at mmc mailing list. I
also want to know why these driver strength is required.
