Please release BL616/618 manual with USB Controller description and registers.

it's FOTG210, take a look at the driver in the linux kernel. register descriptions you can find in GM8136S chip datasheet, just google for it.

Thanks. I'll remain the topic opened to other people access this tip.

The only difference I noticed from the GM8136S usb peripheral is that there is a new additional DMA mechanism called VDMA(Virtual DMA maybe?), which has more DMA slots so you can do more transfers at the same time(old one has only one slot).
