Patch applied.

Duc do you have a datasheet for this GPIO controller?

I want to know if it has further abilities, when I see this:

#define GPIO_SET_DR_OFFSET    0x0C
#define GPIO_DATA_OFFSET    0x14
#define GPIO_BANK_STRIDE    0x0C

It seems like there is a whole bunch of registers there that are not
yet utilized.

Yours,
