/**********************************************************************/



/* 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).
