[PATCH 0/7] Prerequisites for BCM63XX UDC driver

[Kevin Cernekee <cernekee@gmail.com>]

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.
