Please pad out the registers to 8 numbers. See sdm845.

This is different than sdm845. I guess pdc is working?

Ok.. Will address it in the next series.

Yes. For SDM845 pdc controller support was not yet added. That's why
still the GIC interrupt is used.
Where as for SC7180 the same is added with
https://lore.kernel.org/patchwork/patch/1143335/.
Yes. pdc is working.

Cool. The patch that adds pdc to the DT should come before this one
then. In reality, it would be better if it was all squashed down into
one big commit that just introduces the SoC file and one commit for
PMICs and then one commit for the idp board. Then we don't have this
ordering problem.

I'll fix the ordering issues when I respin.
I could squash all of the patches touching the SoC dtsi, but given the
authorship for each varies, I will keep it as is perhaps.
