From mboxrd@z Thu Jan 1 00:00:00 1970 From: "Raju P.L.S.S.S.N" Subject: [PATCH] drivers: qcom: rpmh: avoid sending sleep/wake sets immediately Date: Sat, 25 Aug 2018 01:04:12 +0530 Message-ID: <1535139252-20066-1-git-send-email-rplsssn@codeaurora.org> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: andy.gross@linaro.org, david.brown@linaro.org, linux-arm-msm@vger.kernel.org, linux-soc@vger.kernel.org Cc: rnayak@codeaurora.org, bjorn.andersson@linaro.org, linux-kernel@vger.kernel.org, sboyd@kernel.org, evgreen@chromium.org, dianders@chromium.org, mka@chromium.org, ilina@codeaurora.org, "Raju P.L.S.S.S.N" List-Id: linux-arm-msm@vger.kernel.org Fix the redundant call being made to send the sleep and wake requests immediately to the controller. As per the patch[1], the sleep and wake request votes are cached in rpmh controller and sent during rpmh_flush(). These requests needs to be sent only during entry of deeper system low power modes or suspend.
