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 Manivannan Sadhasivam (3): dt-bindings: mailbox: Add devicetree binding for Qcom IPCC mailbox: Add support for Qualcomm IPCC MAINTAINERS: Add entry for Qualcomm IPCC driver .../bindings/mailbox/qcom-ipcc.yaml | 80 +++++ MAINTAINERS | 8 + drivers/mailbox/Kconfig | 10 + drivers/mailbox/Makefile | 2 + drivers/mailbox/qcom-ipcc.c | 286 ++++++++++++++++++ include/dt-bindings/mailbox/qcom-ipcc.h | 33 ++ 6 files changed, 419 insertions(+) create mode 100644 Documentation/devicetree/bindings/mailbox/qcom-ipcc.yaml create mode 100644 drivers/mailbox/qcom-ipcc.c create mode 100644 include/dt-bindings/mailbox/qcom-ipcc.h -- 2.26.GIT
