20  * DOC: IPA SMP2P communication with the modem
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
36  * clock state bit is valid.  The modem will poll the valid bit until it
40  * we never receive an interrupt from the modem requesting this.
51  * @clock_query_irq:	IPA interrupt triggered by modem for clock query
52  * @setup_ready_irq:	IPA interrupt triggered by modem to signal GSI ready
54  * @notified:		Whether modem has been notified of clock state
75  * ipa_smp2p_notify() - use SMP2P to tell modem about IPA clock state
78  * This is called either when the modem has requested it (by triggering
79  * the modem clock query IPA interrupt) or whenever the AP is shutting down
