From 3b077afb3a7d84bffbf6598697a17655933671d2 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Fri, 14 Mar 2014 14:07:50 +0100 Subject: drm/tegra: dsi - Implement VDD supply support The DSI controllers are powered by a (typically 1.2V) regulator. Usually this is always on, so there was no need to support enabling or disabling it thus far. But in order not to consume any power when DSI is inactive, give the driver a chance to enable or disable the supply as needed.
