-Subject: [PATCH] BCM270X_DT: Add the sdtweak overlay, for tuning sdhost
-
-The sdhost overlay declares the sdhost interface and allows parameters
-to be set. This is overkill for situations where the user just wants to
-tweak the parameters of a pre-declared sdhost interface, so create an
-sdtweak overlay that does just that.
