From 87ab35330c899f5ef3e11fe7d0fc463634f808cb Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Fri, 25 Apr 2014 17:44:51 +0200 Subject: [PATCH] ARM: tegra: dalmore - Add DSI power supply The 1.2V supply for CSI and DSI was previously marked always-on. This is suboptimal because it prevents the supply from being disabled when there is no activity in the display or capture paths that it powers. Hook up the regulator to the DSI output and mark it as not always-on, so that it will only be enabled when DSI actually needs it.
