-/* Linux gpio framework integration.
-*
-* 4 use cases of Alchemy GPIOS:
-*(1) GPIOLIB=y, ALCHEMY_GPIO_INDIRECT=y:
-* Board must register gpiochips.
-*(2) GPIOLIB=y, ALCHEMY_GPIO_INDIRECT=n:
-* A gpiochip for the 75 GPIOs is registered.
-*
-*(3) GPIOLIB=n, ALCHEMY_GPIO_INDIRECT=y:
-* the boards' gpio.h must provide the linux gpio wrapper functions,
-*
-*(4) GPIOLIB=n, ALCHEMY_GPIO_INDIRECT=n:
-* inlinable gpio functions are provided which enable access to the
-* Au1300 gpios only by using the numbers straight out of the data-
-* sheets.
-
-* Cases 1 and 3 are intended for boards which want to provide their own
-* GPIO namespace and -operations (i.e. for example you have 8 GPIOs
-* which are in part provided by spare Au1300 GPIO pins and in part by
-* an external FPGA but you still want them to be accessible in linux
-* as gpio0-7. The board can of course use the alchemy_gpioX_* functions
-* as required).
