-/* Implementation infrastructure for GPIO interfaces.
+/* Character device interface to GPIO.
  *
- * The GPIO programming interface allows for inlining speed-critical
- * get/set operations for common cases, so that access to SOC-integrated
- * GPIOs can sometimes cost only an instruction or two per bit.
+ * The GPIO character device, /dev/gpiochipN, provides userspace an
+ * interface to gpiolib GPIOs via ioctl()s.
