From 7a98786caa18eaa8a5e61382a575f0b6c8e81c01 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Fri, 12 Oct 2012 16:27:28 +0300 Subject: [PATCH] OMAPDSS: DSI: workaround for HSDiv problem It looks like on many OMAP versions powers for both HSClk and HSDiv to be enabled to have a functional HSDiv. This patch fixes the issue by forcing both powers on.
