s3c24xx gpiolib question

Hi,

Is following patch sufficient to add GPJ port support to s3c24xx gpiolib?
And how to switch gpioline to custom function mode (for example TOUT0 on GPB0) 
via gpiolib?

I need to get the gpio number space compressed to get this to
work, it got shuffled out of this round of patches due to urgent
meetings.
