[PATCH 0/6] Add missing wakeup-parent to TLMM

[PATCH 0/6] Add missing wakeup-parent to TLMM

[Konrad Dybcio]

Some TLMM pins are wakeup-capable, but not all platforms described that.

While MPM is not yet hooked up, PDC platforms can and should utilize this
functionality. This series attempts to do so. As part of it, I had to add
PDC support to SDM670, as it apparently hasn't been introduced yet.

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.
