cc2fdf2053
The driver currently supports only dedicated FIFO mode (with dynfifosizing if enabled). Control, bulk and interrupt transfers are supported, isochronous transfers are not yet supported. The driver accesses controller registers using sys_io.h, but for debugging purposes one can get a register map from the driver's config, similar to the usb_dc_dw.c driver. Initial support also has vendor quirks for the STM32F4 SoC family. Tested on NUCLEO-F413HG. Signed-off-by: Johann Fischer <johann.fischer@nordicsemi.no>
