Hi Guenter & all,

I'd prefer that this patch does not go in standalone. The intent for the MIPS 
Boston board is that this driver is enabled for MIPS by this patch:

https://patchwork.kernel.org/patch/9794361/

But not until after earlier patches in that series fix issues with the driver:

https://patchwork.kernel.org/patch/9794355/
https://patchwork.kernel.org/patch/9794357/
https://patchwork.kernel.org/patch/9794359/

That has been held up by disagreement about whether the driver should be using 
0-3 or 1-4 for hardware IRQ numbers, sadly, despite the driver already being 
in tree & clearly broken, and my series not changing which the driver uses...

In any case, I don't really mind if people would rather remove the 
architecture restrictions than just add MIPS, but I'd prefer this doesn't go 
in until the rest of my series since without at least patch 1 of my seres this 
will lead to various WARN()s on Boston boards.

Thanks,
    Paul
