1 GPIOs features

The APQ8064 SoC GPIOs features are as follows
* 90 GPIO pins (GPIO_0 to GPIO_89)
* Configurable pull-up/down
* Configurable output drive current
* Interruptable GPIOs

2 GPIO manipulation

GPIO manipulation is done through the standard gpiolib
The usage / API is well described in kernel/Documentation/gpio.txt.
