Enable GPIO and pinctrl in Kconfig. Add required <mach/gpio.h> for gpiolib. Instantiate the BCM2835 GPIO module in bcm2835.dtsi. Add a pinctrl definition to bcm2835-rpi-b.dts that sets up all of the board's required pinmux configuration. GPIO aren't specified; that's left to gpio_request().

/*
|
|
* The GPIO IP block is designed for 3 banks of GPIOs.
|
|
* Each bank has a GPIO interrupt for itself.
|
|
* There is an overall "any bank" interrupt.
|
|
* In order, these are GIC interrupts 17, 18, 19, 20.
|
|
* Since the BCM2835 only has 2 banks, the 2nd bank
|
|
* interrupt output appears to be mirrored onto the
|
|
* 3rd bank's interrupt signal.
|
|
* So, a bank0 interrupt shows up on 17, 20, and
|
|
* a bank1 interrupt shows up on 18, 19, 20!
