APU1 like mine can use the same driver but with other gpio layout.
A year ago I was in the early stage writing a driver for APU1 until I 
read the datasheet
 Certain GPIOs are multiplexed with pins on the flash controller, PCI 
 controller, GbE MAC, or keyboard and PS/2 controller interfaces
end quote

APU1 uses pinmuxed PS/2 keybord and mouse
APU2 used pinmuxed Hardware monitor pins for FANIN

So I would use this patch which apu1/apu2 board only.
