Hi Mark-PK,

Your driver seems to be for the same interrupt controller IP that is
present in MStar's TV and camera SoCs and now SigmaStar's SoCs.
I sent a series[0] for a driver very similar to yours but for the
MStar SoCs. Do you know if it would be possible to confirm if they are
the
same thing? MediaTek bought MStar a few years ago so it seems likely
but I have no hard information.

If they are the same thing could we work on making one series that
supports both use cases?
It's also possible that if the interrupt controller is the same some
other things like the SPI NOR controller etc are also common and
working
on a single driver for those would save us both time.
