Based on your offline comment:
-----

On going through the bootlogs before posting for I found the following
errors,

[    1.091117] davinci_gpio 601000.gpio: IRQ index 2 not found
[    1.101522] davinci_gpio 601000.gpio: error -ENXIO: IRQ not populated

Some issues in allocating interrupts in case of main_gpio1. I
accumulated the gpio with interrupt numbers. I'll try to debug the
reason behind it and update you with its status. (bootlogs of ti-sdk,
also have this error).

-----

I am going to drop this off my queue, please update if the fixup is some
system configuration error or repost with fix.
