0bb886d2a9 usb: r8a66597-udc disable interrupts on shutdown fix
This patch improves the disable_controller() function in the
r8a66597-udc driver to disable all interrupts and also clear
status flags. With this patch in place the driver survives
kexec.

ef5ce3b690 usb: r8a66597-udc buffer management update
This patch updates the r8a66597-udc buffer management code.

Use fixed buffers for bulk and isochronous pipes, also make
sure to handle the isochronous-as-bulk case. With fixed buffers
there is no need to keep track of used buffers with bi_bufnum.

Also, this fixes a potential buffer offset problem where the
base offset incorrectly varies with the number of pipes used.

The m66592 driver recently got fixed in a similar way.

c41442474a usb: gadget: R8A66597 peripheral controller support.
While in-tree support for the R8A66597 host side has been supported for
some time, the peripheral side has so far been unsupported. This adds a
new USB gadget driver which bridges the gap and finally wires up the
peripheral side as well.
