From 6d7f2d8da106ecf794a5a3e98c4239f348119e3c Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Fri, 5 Feb 2010 00:55:32 -0500 Subject: drm/radeon/kms: dynclks fixes - only r4xx/r5xx/rs6xx/rs740 have clock gating atom table, so disable it on r6xx. it's already disabled on r7xx - check to make sure the clock_gating hook exists before calling it. This avoids a segfault on asics without that function. - remove unused static power management function.
