7 title: Qualcomm Always-On Subsystem side channel
10   - Bjorn Andersson <bjorn.andersson@linaro.org>
14   requests to the always-on subsystem (AOSS), used for certain power management
16   SoC has its own block of message RAM and IRQ for communication with the AOSS.
18   Messaging Protocol (QMP)
20   The AOSS side channel exposes control over a set of resources, used to control
