These patches are intended to lay the groundwork for a new USB Device Controller (gadget UDC) driver. arch/mips/bcm63xx updates include: Clock enable bits DMA descriptor updates New register and IRQ definitions Create platform_device and platform_data Baseline is: git://git.linux-mips.org/pub/scm/ralf/upstream-sfr.git #mips-for-linux-next Note that this is not an OTG-capable controller. Therefore, boards are permanently wired up for either host mode or device mode. Device vs. host can be determined in board_bcm963xx.c based on the detected board ID. Some boards have connectors/pads for both modes, but need to be reworked to run in device mode; usually this involves moving 0-ohm resistors on the D+ and D- lines.
