Subject: [PATCH 7/7] soc: qcom: rpmpd: Add a max vote on all corners at init
Date: Fri, 16 Mar 2018 09:38:24 +0530 [thread overview]
Message-ID: <20180316040824.21472-8-rnayak@codeaurora.org> (raw)
In-Reply-To: <20180316040824.21472-1-rnayak@codeaurora.org>
As we move from no clients/consumers in kernel voting on corners,
to *some* voting and some not voting, we might end up in a situation
where the clients which remove votes can adversly impact others
who still don't have a way to vote.
To avoid this situation, have a max vote on all corners at init.
This should/can be removed once we have all clients moved to
be able to vote/unvote for themselves.
