From daf695fca877068d7533a1b431b09210e5ad0b6b Mon Sep 17 00:00:00 2001 From: Maurus Cuelenaere Date: Tue, 10 Aug 2010 18:02:44 -0700 Subject: arm: samsung: remove pixclock from several boards Since "s3c-fb: Automatically calculate pixel clock when none is given", there's no need for manually calculating the pixel clock anymore so remove these lines and add the correct refresh rate where appropriately.
