From c7fe76721eb546d13fd5576cf135c414136ae4ff Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Tue, 15 Apr 2014 16:27:01 -0600 Subject: [PATCH] ARM: tegra: make Venice's +3.3V_RUN regulator always on This regulator supplies power to pretty much everything on the board, so it doesn't make sense to allow it to turn off. Mark it boot-on and always-on so it doesn't get turned off. Without this, I see issues with the eMMC device; it can't be correctly detected during boot.
