Sorry for the delay, just noticed that I'm supposed to queue
these too. I'll queue these into omap-for-v3.18/mailbox against
v3.17-rc1 and will probably also merge it into omap-for-v3.18/dt
as well.

Regards,

Tony

> Changes in v3:
> - Revised the OMAP mailbox bindings to reflect the updated compatible

>   the v9 framework (Patch 4)
> - Code rearrangement/flip of if code blocks in omap_mailbox probe to address
>   Markus Mayer's comments from v2 (Patch 2)
> - omap_mbox_of_xlate updated to add a missing of_node_put (Patch 4)
> - Adjust the added OMAP non-DT support API, omap_mbox_request_channel, to
>   handle the loss of the chan_name field in the mbox_client structure
>   from v8 to v9 of mailbox framework (Patch 4)
> - Dropped mailbox adaptation changes to TI DSP/Bridge driver, as it will be
>   deleted in 3.17 (Patch 4)
> - No changes to DTS patches (Patches 3 and 5)
> - Tested against v9 of mailbox framework
> 
> v2:
> - http://www.spinics.net/lists/linux-omap/msg109379.html
> - Updated the OMAP DT bindings document for the added back DT properties:
>   "ti,mbox-num-users" and "ti,mbox-num-fifos". Also added information
>   regarding "#mbox-cells" and DT client usage.
> - Updated the OMAP DT adaptation patch to parse the added back DT properties
>   and clean up the previous match data structure.
> - Squashed custom xlate patch into the framework adaptation patch.
> - Tested against v8 of mailbox framework.

> v1:
