Patch looks good Nishant. Do you want to send a patch to update
the config to enable TI_MESSAGE_MANAGER and MAILBOX ? Are we missing
anything upstream yet to enable these ?

for message manager, nothing other than the dts(this patch) and
defconfig changes. I just finished putting the stack together and
re-testing things and they work good. will send the defconfig in a few
mins.
