Galileo Gen 1 GPIO

Fábio Iaione <fabio.iaione at>

Dear Sirs,
I am using Galileo Gen 1 (Cypress I/O expander) and I can not change the GPIO levels.
What GPIO driver should I set in menuconfig tool (DesignWare, PCAL9535, MMIO, Intel SCH)?
What driver name and pin numbers should I use in functions API (gpio_pin_configure, gpio_pin_write, ....)?
Thank you very much.
