Apologies for not testing this. I am not subscribed to the mailing list
and just found this patch. You may CC me or ping me on #linux-msm if you
want anything tested on SDM670 hardware.

The <79 559 30> range is not continuous, just like on SDM845. While PDC
interrupt 93 is on hwirq 573, PDC interrupt 94 is on hwirq 609.
Another patch is needed to fix this because this was already applied.
This does not cause a regression, though, because the pinctrl driver has
no wakeirq map yet.
