Not a public one, but I can confirm this is correct given the internal

Nice catch, I will fix this in v2.

Ok, I will change it. I got confused by the fact that both (usbd and usbh) were 
present on 6318_map_part.h:
#define USBD_CLK_EN (1 << 20)
#define USBH_CLK_EN (1 << 20)

Nit: this should be sar125

This should probably be "usbd" to indicate this is the USB device clock
(not host)

With that fixed:
