The interrupt for power button is static data that comes from the
datasheet, there is no reason to need to define this value on every
board so seams reasonable put this information into the common tps65217
file.

I think there's a problem with these patches where we no longer know
if the interrupts are wired up on a board. For example, if the USB PHY
VBUS interrupt is not connected, the phy driver needs poll the
cable state.

And on some PMICs some pins can be muxed to GPIO mode, don't
remember if that can be done with tps65217.

Regards,

Tony

Hmm, the tps65217 doesn't have a USB PHY like others tps, so not sure
how could affect this patch. Did you see this issue in any board that
uses tps65217 or any am335x based board which commonly uses this pmic?

i don't think this is the case of the boards that use tps65217 as the
pins can't be muxed to GPIO mode.

Oh sorry I misread your patch. I thought you're removing
the interrupts from dts, but you're just moving the dts entries
to the common dtsi file :) So seems just fine with me.

Applying patches 1 and 2 of this series into omap-for-v4.14/dt
thanks.
