-/*********************************************************************
- *
- * This Linux kernel header is expanded from the original driver
- * (gpio_dev) by John Crispin. It provides an ioctl based interface to
- * GPIO pins via the /dev/gpio char device and gpiolib within the kernel.
- * The third argument to each ioctl is the GPIO pin number.
- *
- * This driver has been tested with lk 2.6.31 and works. The original
- * driver fails quietly with this version. The protocol is now a bit
- * different: the ioctl(fd, GPIO_REQUEST, <pin>) should be called
- * after the open("/dev/gpio", O_RDWR) to determine if the <pin> is
- * already in use. If the ioctl is successful (i.e. returns 0 for not
- * in use) then the <pin> is claimed by this driver and
- * ioctl(fd, GPIO_FREE, <pin>) should be called prior to close(fd) .
- *
- * See <kernel_source>/Documentation/gpio.txt
- * Note that kernel designers prefer the use of the sysfs gpio interface.
- * This char driver is easier to use from code and faster.
