- * The following devices are accessible using this driver using

- *
- * For ETRAX 100LX (CONFIG_ETRAX_ARCH_V10):
- * /dev/gpioa minor 0, 8 bit GPIO, each bit can change direction
- * /dev/gpiob minor 1, 8 bit GPIO, each bit can change direction
- * /dev/leds minor 2, Access to leds depending on kernelconfig
- * /dev/gpiog minor 3
- * g0dir, g8_15dir, g16_23dir, g24 dir configurable in R_GEN_CONFIG
- * g1-g7 and g25-g31 is both input and outputs but on different pins
- * Also note that some bits change pins depending on what interfaces
- * are enabled.
