From edea372bd205a30385d4ffbf51afdac62bba478b Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Thu, 21 Dec 2017 12:02:31 +0100 Subject: drm/sun4i: Force the mixer rate at 150MHz It seems like the mixer can only run properly when clocked at 150MHz. In order to have something more robust than simply a fire-and-forget assigned-clocks-rate, let's put that in the code.
