Subject: [PATCH 2/3] soc: qcom: rpmh: Add rpmh_write_sleep_and_wake() function
Date: Thu, 26 Nov 2020 15:48:17 +0530 [thread overview]
Message-ID: <1606385898-8609-3-git-send-email-mkshah@codeaurora.org> (raw)
In-Reply-To: <1606385898-8609-1-git-send-email-mkshah@codeaurora.org>
Let RPMH clients call rpmh_write_sleep_and_wake() to immediately
write cached sleep and wake data to the TCSes.
