Subject: [PATCH V1 2/3] Documentation: sdhci-msm: Add entries for passing load values
Date: Fri, 20 Jul 2018 16:16:05 +0530 [thread overview]
Message-ID: <1532083566-43215-3-git-send-email-vviswana@codeaurora.org> (raw)
In-Reply-To: <1532083566-43215-1-git-send-email-vviswana@codeaurora.org>
The load a particular sdhc controller should request from a regulator
is device specific and hence each device should individually vote for
the required load.
