7 title: Qualcomm IP Accelerator (IPA)
10 - Alex Elder <elder@kernel.org>
13 This binding describes the Qualcomm IPA. The IPA is capable of offloading
17 The IPA sits between multiple independent "execution environments,"
18 including the Application Processor (AP) and the modem. The IPA presents
20 The GSI is an integral part of the IPA, but it is logically isolated
21 and has a distinct interrupt and a separately-defined address space.
