From b4e124c138558a0cff51398ddff9a8e44ed0b529 Mon Sep 17 00:00:00 2001 From: Ville Syrjala Date: Tue, 8 May 2007 00:39:45 -0700 Subject: atyfb: reorganize clock init Reorganize atyfb clock init code so command line clock overrides are effective for all chips. The old code would silently ignore some of the command line clock overrides with some chips.
