-Qualcomm Always-On Subsystem side channel binding
-
-This binding describes the hardware component responsible for side channel
-requests to the always-on subsystem (AOSS), used for certain power management
-requests that is not handled by the standard RPMh interface. Each client in the
-SoC has it's own block of message RAM and IRQ for communication with the AOSS.
-The protocol used to communicate in the message RAM is known as Qualcomm
-Messaging Protocol (QMP)
-
-The AOSS side channel exposes control over a set of resources, used to control
-a set of debug related clocks and to affect the low power state of resources
-related to the secondary subsystems. These resources are exposed as a set of
-power-domains.
