So is this an FPGA soft core PS2 device? Is there any kind of version attached to the soft core? The compatible value should specify an exact version of the implementation that this driver works with. (Newer core versions can claim compatibility with older ones, so the driver's compatible list doesn't need to be exhaustive). Otherwise, this patch looks correct. g.
