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

/* 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).
