Timur Tabi Dec. 8, 2011, 12:04 a.m. UTC 
Create a 32-bit address space version of p1022ds.dts.  To avoid confusion,
p1022ds.dts is renamed to p1022ds_36b.dts.  We also create p1022ds.dtsi
to store some common nodes.

It's not new to this patch, but... what does "8" mean in the second cell
of an mpic interrupt specifier?  And why does the indirect pixis node
not have the interrupt?

I have no idea.

Hmmm... I suppose I could add it, but I don't know what good it would do. 
  The code that's looking for the interrupt is probing on "fsl,p1022ds-fpga".

Valid values are 0 through 3.

Is there a reason why this functionality couldn't be used in indirect
mode?  The device tree describes the hardware, not the limitations of
current Linux support.
