H A Dipa_smp2p.c21 * DOC: IPA SMP2P communication with the modem
23 * SMP2P is a primitive communication mechanism available between the AP and
30 * latter case, the modem uses an SMP2P interrupt to tell the AP IPA driver
34 * power by trigging another SMP2P interrupt to the AP. We communicate
35 * whether power is enabled using two SMP2P state bits--one to indicate
40 * Finally, if the AP kernel panics, we update the SMP2P state bits even if
45 * struct ipa_smp2p - IPA SMP2P information
76 * ipa_smp2p_notify() - use SMP2P to tell modem about IPA power state
77 * @smp2p: SMP2P information
