Well so commit 7e9d474954f4 ("ARM: tegra: Correct polarity for
Tegra114 PMIC interrupt") states that tegra114 inverts the
polarity of the PMIC interrupt. So adding Jon and Thierry to Cc.
So it seems that commit df545d1cd01a ("mfd: palmas: Provide
irq flags through DT/platform data") wrongly sets the
PALMAS_POLARITY_CTRL_INT_POLARITY on IRQ_TYPE_LEVEL_HIGH
while it should set it on IRQ_TYPE_LEVEL_LOW.
Oops, sorry, you seem to have come to pretty much the same conclusion as
I did. I think what we need to do is find a copy of the TRM and see what
exactly the right behaviour is. Or we need to find someone that can take
measurements of the PMIC interrupt pin.
Yeah so either tegra inverts the PMIC interrupt twice now,
or we have also omap5 wkupgen also inverting the PMIC interrupt
once.. Santosh, do you remember if omap5 wkupgen might be
inverting the palmas interrupt?
From the memory, omap5 wakeupgen doesn't invert the irqlines and
not anything specific to PMIC specially either.
