I have been doing some more testing and it appears that I see
intermittent suspend failures on Tegra124 with linux-4.4.y. Apparently
this issue has always been there and appears to be fixed in v4.5. I am
still trying to find a way to fix this. The changes in v4.5 that appear
to resolve this are too complex for stable (several patches in Tegra clk
drivers). Anyway, ignore this for now, I will see how we can fix or
workaround for linux-4.4.y.
