just one part?
According to your patch, exynos5 support 20 banks of gpio right?
I think it's too small.
Please check.

What are PHY0 and PHY1?

Hm.. this is right but,
Since base addresses are same, just do "s5p_cpu_id = readl(EXYNOS4_PRO_ID);"

So.. no need to move.

Please move it to under the exynos4_gpio_part3.

If it support just one part then remove part1. (exynos5_gpio_get_nr)
