1) TXDONE_BY_BLOCK flag :-
Have you tried setting the flag mbox_chan->mbox_client->tx_block ?

2) Implementing TEGRA_HSP_MBOX_TYPE_SM :-
In mailbox framework, a controller is a collection of identical
channels. That is, instances of the same class.
So ideally, in probe you should populate a controller for each
type of channel, i.e, DB, SM, SS and AS.
