#gpio-cells property. Add a new ofw_bus method (OFW_BUS_MAP_GPIOS()) that allows the GPIO controller to implement its own mapping to deal with gpio-specifiers, allowing the decoding of gpio-specifiers to be controller specific. The default ofw_bus_map_gpios() decodes the linux standard (#gpio-cells = <2>) and the FreeBSD standard (#gpio-cells = <3>). It pass the gpio-specifier flag field to the children as an ivar variable so they can act upon. |
