From 4e6a0ab0f9d4c8062bd84f3fc95b175001d46ebf Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Wed, 3 Aug 2011 14:13:52 +0300 Subject: [PATCH] OMAP4: TWL: Add common omapdss supplies OMAP DSS normally gets power from VCXIO on OMAP4. Add configuration for this into twl-common.c Mark VCXIO as always_on, as VCXIO is used by multiple components, including the MPU, and turning it off when DSS doesn't need it would lead the device to halt.
