DESCRIPTION
The fdtbus abstract bus driver is the primary connection and translation layer between fdt(4) hardware resources description and FreeBSD native newbus device drivers framework. For an embedded system fdtbus represents peripherals typically found on a highly integrated chip (system-on-chip). The fdtbus driver provides generic, common infrastructure for all fdt(4) oriented device drivers, and its main responsibilities are the fol- lowing: o Creating newbus children that reflect fdt(4) nodes in the flattened device tree. o Managing SYS_RES_IRQ resources. o Managing SYS_RES_MEMORY, SYS_RES_IOPORT resources.
