Subject: [PATCH 0/3] Add changes to support 'HW solver' mode in rpmh driver
Date: Thu, 26 Nov 2020 15:48:15 +0530 [thread overview]
Message-ID: <1606385898-8609-1-git-send-email-mkshah@codeaurora.org> (raw)
RSC controllers may be in 'HW solver' state, where they could be in
autonomous mode executing low power modes for their hardware and as
such are not available for sending active votes.
This series adds changes to support the same in rpmh driver by disallowing
active requests when in solver mode and allowing the drivers to write
cached sleep and wake votes immediately.
Note: The series can land on its own but to avoid conflicts with
other change going in rpmh driver i have based changes on top of [1]
which hopefully can land soon.
