What if...

int s3c24xx_get_pclk(void);
int s3c64xx_get_pclk_msys(void);
int s3c64xx_get_pclk_psys(void);

And in some driver:

#ifdef ...
    x = s3c24xx_get_pclk();
    x = s3c64xx_get_pclk_msys();

In some other driver:

#ifdef ...
    x = s3c24xx_get_pclk();
    x = s3c64xx_get_pclk_psys();

Ho to do that correctly? Right now I prefer that way:

int s3c_get_some_driver_clk(void);
defined somewhere in arch/***
