From 31767e00e428c891343f94e5a94909bb7a642bcf Mon Sep 17 00:00:00 2001 From: Archit Taneja Date: Wed, 17 Jan 2018 15:04:47 +0530 Subject: [PATCH] dt-bindings: display: msm/dsi: Add compatible for 14nm DSI PHY Add the compatible string for 14nm DSI PHY (used in MSM8996/APQ8096). >From 14nm PHY onwards, the "dsi_phy_regulator" reg-name is not required, but "dsi_phy_lane" reg-name is. Update the doc to specify the reg-names each PHY revision needs.
