Hi,

This patch add the support of GPFx pin of Exynos5433 SoC. Exynos5433 has
different memory map of GPFx from previous Exynos SoC. Exynos GPIO has
following register to control gpio funciton. Usually, all registers of GPIO
are included in same domain.
- CON / DAT / PUD / DRV / CONPDN / PUDPDN
- EINT_CON/ EINT_FLTCON0, EINT_FLTCON1 / EINT_MASK / EINT_PEND

But, GPFx are included in two domain as following. So, this patch supports
the GPFx pin which handle the on separate two domains.
- ALIVE domain : CON / DAT / PUD / DRV / CONPDN / PUDPDN
- IMEM domain  : EINT_CON/ EINT_FLTCON0, EINT_FLTCON1 / EINT_MASK / EINT_PEND
I'm afraid I don't get anything from the description above. Could you
describe the layout of registers in memory map and IRQ routing of the
pins?

Best regards,
Tomasz
