Greetings Andy,

Thank you for this feedback. After exploring the gpio_regmap it seems
it does not fit my needs. Some of the GPIOs are a combination of
several bits in a byte. For instance the Health LED or Identify LED have
more than 2 states. If acceptable I believe the gxp-gpio-pl.c file should
not use the gpio_regmap.

Thanks,
