From: Ville Syrjälä Date: Thu, 22 Apr 2010 20:50:09 +0000 (+0200) Subject: OMAP: DSS2: DSI: Disable interface when disabling the display X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=d73701044b70924f450fc6b161d952b38b7d0182;p=deliverable%2Flinux.git OMAP: DSS2: DSI: Disable interface when disabling the display 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.
