dtc points out that the interrupts for some devices are not parsable:

picoxcell-pc3x2.dtsi:45.19-49.5: Warning (interrupts_property): /paxi/gem@30000: Missing interrupt-parent
picoxcell-pc3x2.dtsi:51.21-55.5: Warning (interrupts_property): /paxi/dmac@40000: Missing interrupt-parent

There are two VIC instances, so it's not clear which one needs to be
used. I found the BSP sources that reference VIC0, so use that:

Rob has a series to remove Picoxcell as there's no active development on
this anymore and Intel have stopped producing the chips.

Right, I am aware of Rob's series. My patch was a little older but I only got
around to submitting it now. I'd still like to merge it as a bugfix for v5.11
though and have it backported to avoid the warnings with new dtc on
stable kernels, while doing the platform removal for v5.12.
