From d73701044b70924f450fc6b161d952b38b7d0182 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 22 Apr 2010 22:50:09 +0200 Subject: OMAP: DSS2: DSI: Disable interface when disabling the display MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Once the DSI PLL is separated from the DSI display a full DSI reset will not be performed every time the display is enabled so the interface and VCs must be disabled when disabling the display. If the VCs are not disabled some register accesses will abort.
