Subject[PATCH V3 2/3] dt-bindings: mmc: sdhci-msm: Add entries for passing load values
Date
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.
