No, based on the "fsl-ehci" name, which is only used as a child
of the drivers/usb/host/fsl-mph-dr-of.c dual-role driver.
I looked for drivers that call platform_device_add() and manipulate
the dma_mask of that child.
Sorry for missing this one when I did the description. I believe
it is correct though. The DMA settings on powerpc are probably correct
in this case, but the existing code doesn't allow you to describe
on-board USB devices with additional properties as children of
the dual-role device node.
