Subject: [PATCH 4.16 243/272] dt-bindings: display: msm/dsi: Fix the PHY regulator supply props

4.16-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Archit Taneja <architt@...eaurora.org>

[ Upstream commit 8c4905fd4939c59e0f7993ba34883e328eef4b59 ]

The PHY regulator supply names vary across different PHY versions.
Mention explicitly which PHYs require which supplies.
