This is exactly I looked for a month ago, when I was porting keyboard
for chromebook. Keyboard depends on Chrome Embedded Controller (EC),
which provides external gpio interrupt, and the overall interrupt
controllers on exynos tree looks like:
nexus0 (1 irq)
|
\--gic0 (160 irq)
|
\--combiner0 (32 groups, 8 irq per group at max)
|
\--gpio0 (205 irq)
|
\-- Chrome EC Keyboard
So seems supporting standard exynos DTS from samsung becomes easier now.
thanks.
