From 88257b26953f73f30acf49587cb42b84be43c587 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Mon, 20 Dec 2010 16:26:22 +0200 Subject: [PATCH] OMAP: DSS2: DSI: ensure VDDS_DSI is disabled on exit The panel drivers can leave the VDDS_DSI regulator enabled, even when the panel is disabled, to ensure that the DSI pins are powered. This patch ensures that VDDS_DSI is disabled on DSI module unload.
