soc: qcom: ipa: AP/modem communications This patch implements two forms of out-of-band communication between the AP and modem. - QMI is a mechanism that allows clients running on the AP interact with services running on the modem (and vice-versa). The AP IPA driver uses QMI to communicate with the corresponding IPA driver resident on the modem, to agree on parameters used with the IPA hardware and to ensure both sides are ready before entering operational mode. - SMP2P is a more primitive mechanism available for the modem and AP to communicate with each other. It provides a means for either the AP or modem to interrupt the other, and furthermore, to provide 32 bits worth of information. The IPA driver uses SMP2P to tell the modem what the state of the IPA clock was in the event of a crash. This allows the modem to safely access the IPA hardware (or avoid doing so) when a crash occurs, for example, to access information within the IPA hardware.

net: ipa: include some standard header files Some IPA header files use types defined in <linux/types.h>, but do not include that file: - In "ipa_mem.h", the ipa_mem structure has u16 and u32 fields - In "ipa_power.h", ipa_power_retention() takes a bool argument, and ipa_core_clock_rate() returns u32 - In "ipa_version.h", ipa_version_supported() returns bool Include it in these files to satisfy their dependencies. The ipa_qmi structure (defined in "ipa_qmi.h") contains a work structure, so include <linux/workqueue.h> in there. All of the data and register definition files, as well as "reg.h", use the ARRAY_SIZE() macro. Include <linux/array_size.h> everywhere it's used. Similarly, all register definition files (and a few others) use the GENMASK() macro, so include <linux/bits.h> to ensure it's defined where used. BIT() becomes available by including this file also.
