7 title: OMAP GPIO controller
10   - Grygorii Strashko <grygorii.strashko@ti.com>
13   The general-purpose interface combines general-purpose input/output (GPIO) banks.
14   Each GPIO banks provides up to 32 dedicated general-purpose pins with input
15   and output capabilities; interrupt generation in active mode and wake-up

67       Do not reset on init. Used with ti,hwmods on some legacy OMAP SoCs which
