13   The Inter-Processor Communication Controller (IPCC) is a centralized hardware
14   to route interrupts across various subsystems. It involves a three-level
18   a case, the client would be Modem (client-id is 2) and the signal would be
19   SMP2P (signal-id is 2). The SMP2P itself falls under the Multiprocessor (MPROC)
20   protocol (protocol-id is 0). Refer include/dt-bindings/mailbox/qcom-ipcc.h
