Subject: [PATCH V2 2/3] dt-bindings: mmc: sdhci-msm: Add entries for passing load values
Date: Thu, 20 Sep 2018 11:52:37 +0530	[thread overview]
Message-ID: <1537424558-17989-3-git-send-email-vbadigan@codeaurora.org> (raw)
In-Reply-To: <1537424558-17989-1-git-send-email-vbadigan@codeaurora.org>

From: Vijay Viswanath <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.
