21 * DOC: IPA SMP2P communication with the modem
23 * SMP2P is a primitive communication mechanism available between the AP and
24 * the modem. The IPA driver uses this for two purposes: to enable the modem
29 * This initialization is done either by Trust Zone or by the modem. In the
30 * latter case, the modem uses an SMP2P interrupt to tell the AP IPA driver
33 * The modem is also able to inquire about the current state of IPA
34 * power 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
