=== Highlights ===
* Attended Linaro Connect from Feb 6 - 10
* Rebased iommu hwmod work onto Ohad's rpmsg-branch, created github tree for him to check on the changes.
* Setting up OMAP3 ISP testing environment, to test iommu changes without a sensor, following instructions received from Laurent Pinchart.
* Looking at device tree for mailbox.
* Tidspbridge work: - Tracking inclusion of memory leak fixes for tidspbridge. - Patch to solve a L3 warning due to a missing wdt clock on the dsp side.

Do we need to revisit the topic of creating a mailbox subsystem as part of the problem space here?

I think if we have various per-SOC implementations with different APIs, it would make sense to do so consolidate them all. Is there a pointer to prior discussion on this topic that I could use to create a roadmap card?

I don't know if my memory serves me right but there was a discussion a while back about the OMAP mailboxes and whether they needed a subsystem on their own.
(I cannot find it now...)
Either the conclusion was "we should look into it sometime" or "too little code to worry about".
I even have a vague memory of someone proposing drivers/mailbox for OMAP once, but might not remember correctly.
Ohad/Tony probably knows...
Candidates would be:
arch/arm/plat-omap/mailbox.c arch/arm/mach-omap1/mailbox.c arch/arm/mach-omap2/mailbox.c arch/arm/mach-ux500/mbox-db5500.c Portions of: drivers/mfd/db8500-prcmu.c + some new code I think Sjur Brændeland have cooking for drivers/modem-shm

I think it was "we should look into it sometime" :)
It's not a hell lot of code, but it seems there are enough similarities for us to (at least) look into it.
Candidates would be:
git grep mailbox yields additional results, but it's not clear upront if they're really about additional mailbox hw or just unrelated drivers with similar nomenclature.
Thanks, Ohad.
