Hello,
This series adds mailbox driver support for Qualcomm Inter Processor Communications Controller (IPCC) block found in MSM chipsets. This block is used to route interrupts between modems, DSPs and APSS (Application Processor Subsystem).
The driver is modeled as a mailbox+irqchip driver. The irqchip part helps in receiving the interrupts from the IPCC clients such as modems, DSPs, PCI-E etc... and forwards them to respective entities in APSS.
On the other hand, the mailbox part is used to send interrupts to the IPCC clients from the entities of APSS.
This series is tested on SM8250-MTP board.
Thanks, Mani
Changes in v3:
* Added Bjorn's review tags * Few changes to DT binding as suggested by Rob
Changes in v2:
* Moved from soc/ to mailbox/ * Switched to static mbox channels * Some misc cleanups
