So is there some IP on Tegra called "Tegra PMC" that is
inverting the interrupt? Or is the "Tegra PMC" that commit
7e9d474954f4 mentions just the palmas configuration for
inverting the interrupt?

The problem I'm having is With omap5 where I can only get the
PMIC interrupts working with IRQ_TYPE_LEVEL_HIGH if
PALMAS_POLARITY_CTRL_INT_POLARITY is not set unlike for
Tegra.
