- Looking at device tree for mailbox.
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
