Subject: [PATCH 00/12] Use qmp_send to update co-processor load state
Date: Fri, 16 Apr 2021 17:33:46 +0530
Message-ID: <1618574638-5117-1-git-send-email-sibis@codeaurora.org> (raw)

The power domains exposed by the AOSS QMP driver control the load state
resources linked to modem, adsp, cdsp remoteprocs. These are used to
notify the Always on Subsystem (AOSS) that a particular co-processor is
up/down. AOSS uses this information to wait for the co-processors to
suspend before starting its sleep sequence. These co-processors enter
low-power modes independent to that of the application processor and
the load state resources linked to them are expected to remain unaltered
across system suspend/resume cycles. To achieve this behavior lets stop
modeling them as power-domains and replace them with generic qmp_send
interface instead.
