Yes, I've figured out the origin here. It was user error, in that I was
not nesting the device node under the soc node, which had the
interrupt-parent property. Moving it there fixed that issue.

In any case, I've ran into another problem. Basic gist is, I was giving
it a go on my hi3521a board, because reading the registers for that and
comparing it to the source, I find they are nearly bit-for-bit
identical, but I suppose there is some tweakage needed to make it work
100%.

What information would it take to have this driver expanded to enable a
new, similar SoC?
