20 * DOC: IPA SMP2P communication with the modem
22 * SMP2P is a primitive communication mechanism available between the AP and
23 * the modem. The IPA driver uses this for two purposes: to enable the modem
28 * This initialization is done either by Trust Zone or by the modem. In the
29 * latter case, the modem uses an SMP2P interrupt to tell the AP IPA driver
32 * The modem is also able to inquire about the current state of the IPA
33 * clock by trigging another SMP2P interrupt to the AP. We communicate

13 The Inter-Processor Communication Controller (IPCC) is a centralized hardware
14 to route interrupts across various subsystems. It involves a three-level
17 Modem's interrupts via Shared Memory Point to Point (SMP2P) interface. In such
18 a case, the client would be Modem (client-id is 2) and the signal would be
