Subject: [PATCH 1/3] soc: qcom: rpmh: Update dirty flag only when data changes
Date: Tue, 4 Feb 2020 11:43:49 +0530 [thread overview]
Message-ID: <1580796831-18996-2-git-send-email-mkshah@codeaurora.org> (raw)
In-Reply-To: <1580796831-18996-1-git-send-email-mkshah@codeaurora.org>
Currently rpmh ctrlr dirty flag is set for all cases regardless
of data is really changed or not.
Add changes to update it when data is updated to new values.
