k2g has two instances of gpio controller. The gpio controller
is bit identical to the one used in da-vinci. The da-vinci gpio
driver was written keeping in mind about only one instance of
gpio controller. The patch series enhances the driver to support
multiple instances.
k2g has 2 instances of gpio controller with 144 pins each.
Totally 9 banks with 16 pins each totalling to 144 pins per
controller instance. GPIO1 instance has GPIO:68 to GPIO:143
marked as reserved hence we have a total of 144(bank0) and 68
(bank1) GPIOs.
