In terms of users, the OMAP mailbox adaptation patches to this framework
is ready [1], and this is one of the main dependencies to achieve PM
suspend/resume on the TI AM335/AM437 SoCs. I would have to rebase the
patches onto the appropriate -rc with the framework patches in, as the
remaining mailbox dependencies did make it into 3.18-rc1. I was
initially hoping that this would be 3.18-rc1, and the OMAP patches to
make it into 3.19, but if this is going to be 3.19, then the OMAP
adaptation can be baselined off an immutable mailbox framework branch,
and come through the arm-soc tree as well.
