Support for high/low and rising/falling edges was something I looked
at briefly but never upstreamed. Unifying the drivers now would indeed
be a good thing.
I've done the usual test on UC-7112-LX with the following patches
applied to next-20170310:
[2/4] irqchip: refactor Gemini driver to reflect Faraday origin
[3/4] irqchip: faraday: fix the trigger types
[4/4] RFT: irqchip: replace moxa with ftintc010
Log [1] is with MMC unavailable (another issue that needs a fix in DT)
and [2] when MMC is there.
I suspect some of the IRQ flags in arch/arm/boot/dts/moxart.dtsi may
not be set right / they don't match up against the "interrupt-mask"
property we probably want to get rid of. Any tips on what those flags
really should be?
